The concept of a bank has undergone a radical transformation. As we navigate through 2026, the traditional brick-and-mortar boundaries have dissolved, replaced by a seamless, invisible layer of connective tissue known as Application Programming Interfaces (APIs). This guide explores how the UAE has become a global leader in this API Economy, leveraging a 3,000-word deep dive into the technology, regulation, and practical application of banking APIs within the Emirates.
As futurist Brett King famously predicted, by 2030, billions of people will use day-to-day banking services completely independent of traditional banks. In the UAE of 2026, this vision is already a reality. Whether you are paying for a Careem ride, splitting a bill at a Dubai Mall restaurant, or securing an instant SME loan in Abu Dhabi, you are interacting with banking APIs.

Decoding the Digital Connective Tissue – What are Banking APIs?
At its core, an Application Programming Interface (API) is an intermediary that allows two software applications or computer programs to communicate, read, and exchange data securely. They operate using set protocols and definitions, enabling developers to build innovative products without needing to understand the complex internal code of a bank’s legacy system.
The Practical Reality in 2026
Consider the most common modern banking experience: signing up for a new investment app. Instead of manually entering your name, Emirates ID details, and email address, you can simply sign in with UAE Pass or a major bank ID. This instant data exchange is powered entirely by APIs. The app uses an API to securely communicate with your identity provider or bank, fetching your verified data without ever seeing your private passwords.
A History of Innovation – From Salesforce to the CBUAE
The journey to the UAE’s current API-first environment began over two decades ago.
- 2000-2004: Salesforce launched the first API, followed by Flickr’s photo-sharing platform.
- 2006-2008: Google and Facebook revolutionized data sharing, while Twilio proved that APIs could be standalone products for communication.
- 2018: The European Parliament’s PSD2 mandate forced banks to share their banking APIs publicly, birthing the Open Banking movement.
- 2024-2026 (The UAE Leap): While other markets struggled with legacy debt, the Central Bank of the UAE (CBUAE) launched its Open Finance Framework, mandating that every licensed financial institution in the country participate in a centralized API hub.
The UAE Taxonomy – Three Types of APIs
In the Emirates’ 2026 financial ecosystem, APIs are categorized by their accessibility:
| Public/Open APIs | Private/Internal APIs | Partner APIs |
| These are accessible to any licensed fintech or developer. In the UAE, these are often used for identity verification (e.g., PAN or Emirates ID verification records). | These stay within a single institution, like Emirates NBD or FAB. They are used to connect a bank’s modern mobile app to its older legacy backend servers. | These offer restricted, often paid access to specific collaborators. This is the foundation of Banking-as-a-Service (BaaS) in Dubai, where a fintech might pay a bank to issue its own branded cards. |
Objectives of Banking APIs
Most traditional financial institutions heavily depend on legacy systems and established procedures when performing their operations. However, these banks are leveraging APIs not only to share externally but also to address internal technology-related issues, such as server downtime, information accessibility, and internet speed, to name a few.
Faster Transaction Speed
APIs enable agility by operating on an information-sharing principle that allows two software or computer programs to communicate and share data. With APIs, whether external or internal, organizations can increase their transaction or information processing agility.
While internal APIs can increase the speed of information flow within the organization, external APIs can also reduce processing time for transactions.
Lower IT Complexity
Complexity in information technology is a challenge in many organizations due to limited access to the required information. Information technology is based on data or information, and if such information is complex or not readily accessible, the technology alone cannot do wonders.
APIs bring parity between information access and technology, so organizations can use IT advancements to their fullest. Accessible information is crucial for product development, and APIs bring that access to businesses.
Bring Innovation
With the introduction of PSD2, which required banks in Europe to share their APIs, the idea of sharing APIs enabled an innovation drive. Many non-bank companies (such as NBFCs, account aggregators, or other organizations not involved in offering financial services and products) began using open APIs to develop customer-centric, solution-driven products.
If APIs were not publicly shared, the innovation would not have been possible, and the available information would have been wasted. Different APIs serve different purposes: accounting APIs make accounting and bookkeeping simpler, whereas banking APIs make banking faster and smoother.
Boost Partnerships
The idea of API sharing is based on partnerships. The concept of APIs is built on information sharing, and without partnership or collaboration, APIs do not improve the customer experience.
With the launch of APIs, many banks partner with fintech and non-bank companies to develop innovative, technology-driven banking products and services.
Smooth Regulatory Compliance
Since information sharing via APIs is safe, it enhances regulatory compliance, as each API is documented. Since every API is documented, its lifecycle, use, and functionality are readily available.
When information sharing becomes easy, regulatory compliance becomes smooth and secure. The APIs, through information sharing, can help automate statutory obligations and support robust compliance procedures within an organization. Thus, APIs serve multiple objectives, with a primary aim of easing customers’ daily lives by enabling technological innovation.
Why the UAE Mandated an API-First Strategy
The CBUAE’s decision to mandate APIs wasn’t just about technology; it was about economic agility. The core objectives include:
- Faster Transaction Speed: APIs enable real-time information sharing, meaning a cross-border transfer from Dubai to London that used to take days now settles in seconds.
- Lower IT Complexity: Instead of building a new banking app from scratch, developers use APIs as Lego blocks, dramatically reducing the time it takes to launch a new product.
- Embedded Finance Innovation: By sharing data, banks have enabled non-financial companies (like e-commerce giant Noon) to offer credit and insurance directly at the checkout page.
Four Pillars of Banking APIs
Various support pillars play a crucial role in making an API a successful product. Suppose a particular API is widely prevalent or highly profitable. In that case, it is because of the collective efforts put into making that API a successful outcome by the four pillars discussed below:
API Strategy
An API strategy is a documented API that describes how it works, the mechanisms required to use it, and the benefits of using it.
Having a clear API strategy is key to the success of every API. A banking API needs to be highly usable, have a transparent, documented process, and be scalable. Hence, a banking API needs a clear API strategy that provides a strong foundation for broader adoption across companies.
The four phases of the API strategy, as outlined below, require rigorous research and dedication, both technically and from a business perspective.
- Preparing a digital blueprint of an API strategy
- Aligning the strategy to the organizational goals
- Develop additional technology that supports the strategic objectives
- Evaluate and Act
Human Efforts
Although the banking API concept is highly technology-driven and involves minimal human intervention, it is possible only because of dedicated human efforts to solve customers’ problems with performing banking transactions.
Mostly, human effort is undervalued, especially in technology. But, it should be remembered that the technology was invented only because necessary and intelligent human measures were taken.
Therefore, banking APIs must have a robust human capital pillar that can make or break the entire API. Moreover, building banking APIs is an ongoing process that requires human effort in addition to technological capabilities.
Certain banks encourage humans to build more innovative APIs by enabling gamification in the organization. They also offer rewards and incentives to employees who create the most popular API that the other players mainly use.
Thus, human effort is one of the four pillars for building an innovative, highly usable banking API.
Technological Immunity
Technology is the very base of the banking APIs. Banks, fintech companies, and other non-bank players will have to be technologically sound to keep adding more helpful banking APIs.
Technologically advanced organizations will have additional capabilities, as this is the foremost requirement for building banking APIs.
Banking API leaders must focus on building functional, secure internal APIs first, then gradually expand to create external and partner APIs. If internal APIs are not robust and usable, the other types of APIs may also not be as valuable as they could have been.
One critical consideration for a technologically-immune organization is automating the API documentation process, which will save developers a lot of time. They can focus on solving the core problems by bringing innovation to other banking APIs.
Operating Framework
An organization’s operating framework is another essential pillar of building a highly usable banking API. Delivering an API strategy that sets clear objectives and functionality reflects successful operational capabilities.
While building an API, Banks need a cohesive operating model that streamlines the API strategy from creation to decomposition, rather than segmenting each part and working on it separately. An operating framework defines the extent to which a banking API should be acceptable, as it will be developed within its ambit.
Hence, defining a comprehensive operating framework is crucial to building a banking API that is seamless, widely adopted, and, most importantly, solves customers’ problems.
The banking APIs need to be collectively usable, scalable, and user-friendly to capture the consumer market and offer innovative banking products.
Now that we have covered the meaning, functionalities, and pillars of banking APIs, let us learn each category in detail.
Core Banking APIs
While every banking API plays a role in disrupting how banking is done, core banking APIs are the most crucial, widely used, and in greater demand than other banking APIs.
Core banking APIs generally provide developers and other businesses with information about essential banking services such as account opening, accepting deposits, and making domestic or international payments.
Core banking APIs also include statements API, transactions API, and data aggregation API that provide information about the potential customer, using which developers can customize their products.
The information below provides an explanation of various types of core banking APIs with the help of examples.
Types of Core Banking APIs
Core banking APIs build on basic banking APIs and allow customers to seamlessly experience banking products and services without worrying about data security. Different types of core banking APIs cater to various developer use cases.
It may also happen that the developer may need more than one core banking API to build their product, and this complexity is simplified by the banking API providers.
Account Opening API
Account opening is a requirement for almost every business or consumer to avail of the services provided by them, e.g., to use a mobile application or subscribe to a service. Whether banks, fintech companies, or non-bank companies, opening an account is a mandatory step to start using a product or service.
Account opening APIs simplify entering your information every time you use a new product or service. Let us understand how account opening API works:
- You want to open online bank accounts for the interns working at your company.
- Typically, opening account procedures are a bit cumbersome and require certain KYC documents to be verified, which you may need to submit in physical form.
- Instead, you will approach an API provider to connect you to the bank and initiate the account opening of your interns.
- The account-opening API provider will request that banks provide banking infrastructure and initiate account creation.
- The account opening API provider will approach the bank, fetch the necessary details, and complete the account opening procedure.
- You will have all your interns’ accounts opened with your desired bank faster and more efficiently.
The advantage of using the account-opening APIs was that the customer could efficiently complete the task while saving significant time gathering and submitting the details. You will not prefer opening accounts directly with banks mainly because they lack integration capabilities, lack API documentation, and are resistant to complying with impractical requirements, etc.
Thus, the account opening API is one of the most popular core banking APIs widely used across sectors.
Deposit APIs
As the name suggests, deposit APIs help users create bank deposits with a bank or a third-party service provider using their preferred payment methods.
Typically, a deposit-making process at traditional financial institutions would require you to either visit the branch or create one using online banking. You would give cash, a cheque, or your bank could directly deduct from your bank account.
Hence, you had to make deposits using the banks’ preferred payment method. With the launch of the deposit APIs, you can now make deposits using your preferred payment methods, such as m-wallets, credit cards, and mobile banking.
Deposit APIs serve the following purposes for you and for the company building a deposit as a product, which could be a fintech or a non-bank company:
- Simple integration of software programs
- Greater usability for consumers
- Faster information sharing
- Enhanced data security
Let’s understand how deposit APIs work with the help of an example:
Mohamed, a Master of Commerce student from Indore, uses one app, VenPay (fintech startup), quite frequently on his phone to pay his rent, recharge his phone, book a movie ticket, and order food.
He wants to make a small deposit of AED 20,000, which he received as a prize for winning an international quiz competition.
The VenPay app will also allow him to deposit AED 20,000 using a deposit API. When Mohamed initiates the deposit transaction, VenPay will send a request to the deposit API provider to obtain KYC and other personal information from Mohamed’s bank.
An API provider will then send requests to Mohamed’s banks to fetch his relevant information, create a deposit, and share it with VenPay. Once the details are confirmed, Mohamed will have his deposit made in just a few taps in the app on his phone.
Statements API
The bank statement APIs are a type of banking API that allow users to read bank statements, integrate the details with a TPP, build an end product or service, or use them as an enhanced service provision. Statements APIs can be used for multiple purposes, such as bank reconciliation, customer spend analysis, and bank statement accounting.
The statements API is a widely used core banking API that many fintech or non-bank companies use to integrate with their products or services.
For example, you use the accounting software Niro to record the accounting entries and generate financial statements for your business. One of the most time-consuming tasks in accounting is reconciling the bank balance with the bank statement.
The Statements API can solve this problem when your accounting software, Niro, approaches a statements API provider to request bank statement details.
It will then send the request to your banks, where you have your accounts, and the banks will return the information to the API provider, which will then communicate that to Niro. Niro will integrate the statements API in his software and use the data fetched by it to reconcile the bank balance.
The entire process will take only two minutes, whereas doing it manually could take hours.
Payments APIs
The payments APIs enable users to offer customers a seamless, faster, and safer payment experience by enabling multiple payment options. It helps merchants add various payment options to increase customer acceptance, while customers benefit from choosing the most suitable and convenient option.
Payments APIs also communicate between banks and TPPs to exchange customer information, just as any other banking API does. These APIs allow customers to pay via credit cards, m-wallets, net banking, BNPL, etc.
Earlier, only three payment options were available for online shopping: card, net banking, or cash on delivery. To pay by card, you must have the card details with you; to pay via net banking, you need to remember your user ID and password.
The payments API has revolutionized checkout by offering multiple payment options so customers can pay with a single tap. Let’s learn how the payments API works.
- You visit a nearby dairy shop and buy milk.
- While making the payment, you remember you forgot your wallet, but you had your phone with you.
- The shopper asks you to download the VenPay app and scan the QR code to make the payment.
- When you download and create a VenPay account, it uses the account-opening API to fetch your bank account details.
- The QR code will send a request to the payments API provider to receive your bank details.
- The API provider will then send the request to your bank and send the details to VenPay.
- VenPay will then complete your payment, and all of this was done with just one tap in seconds.
Thus, payment APIs have paved the way for a major revolution in open banking, enabling TPPs to offer customizable, innovative banking products and services.
Financial Data API
The purpose of the financial data APIs is to share and integrate the customers’ financial information to develop creative banking products and services. The financial data APIs allow developers to integrate financial information into individual data sets to build their products or services.
It is a data aggregation API that connects two software programs or applications to analyze data and convert it into actionable insights. These APIs then convert the datasets into payments, customer onboarding information, and other useful datasets.
Let’s see how financial data aggregation APIs work:
For example, you want to check how much you spent across e-commerce platforms and other apps in a particular month. Now, you will approach a TPP ‘Spense’ that has developed a fintech product that will provide your spend analysis for a specific period.
You had already linked your information when you created an account on Spense, including bank statements, app wallets, and credit cards. When you request that this app perform a spend analysis for a specific month, Spense will use the financial data API to request the details from an API provider.
The API provider will request banks, third-party accounts, wallets, and card network companies to fetch your details and return them to Spense. Spense will then perform its analysis and share the outcome with you.
The spend analysis is done in the blink of an eye, which was not so quickly possible earlier without the open sharing of such financial data APIs.
That completes the core banking APIs and their widely used types among customers, since they are pretty basic banking APIs. Let’s move on to our next banking API – card issuance APIs that help you create, manage credit cards, and generate card PINs.
Card Issuance APIs
Since the launch of open APIs, multiple APIs have been developed every day, offering various uses. You name the service, and you will find an API for that service or product, making service consumption faster and more convenient.
Card issuance APIs are banking APIs that enable developers and third parties to create, issue, and manage credit/debit cards, either physically or virtually. These APIs enable users to integrate card services into their existing product offerings or to create a new credit/debit card.
Physical Cards Vs. Virtual Cards
Primarily, we all have used physical credit/debit cards. Still, the issue with physical cards is that you have to carry them every time you make a purchase, or you have to remember the card details (16-digit card number, expiry date, and CVV).
Moreover, once you use your credit/debit card details to buy an item online, you expose your confidential information to other merchants, and you do not have a guarantee that it is secure.
Virtual cards let you store your card details in an app, so you do not need to remember or carry them every time you make a transaction. Virtual cards are credit or debit cards created and issued virtually through a mobile app on your phone and act as your physical credit card, but they have no physical form.
Virtual cards have 16-digit card numbers, and they are stored in your app. Many companies issue one-time-use virtual cards that generate a unique 16-digit card number each time you make a purchase, and the card expires as soon as the transaction is complete.
The advantage of one-time-use virtual cards is that your card details, which are exposed to merchants, cannot be misused because they are invalidated after their first use. Hence, for the next purchase, your virtual card (master virtual card number) will generate a new unique 16-digit number for the payment.
You can also limit your spending and offer it to your employees for their traveling and reimbursement expenses. The advantage of virtual cards is that you can document each employee’s spending using them.
Benefits of Virtual Cards
- Enhanced data and privacy security
- Single card, multiple unique tokens for each transaction
- Offers control over every spend through an app
- Convenient to use since details are stored in an app
- Subscription and vendor management
Many companies use such virtual cards to issue to their employees and offer them credit card benefits as part of their remuneration package. At the same time, certain other companies issue credit cards to their customers and offer rewards for every purchase made with them.
Before we learn various types of APIs, let us first understand how a credit/debit card transaction works.
How Do Credit Card Transactions Work?
Typically, a card is issued by a card-issuing company, such as a bank, fintech company, or non-bank. In contrast, card transactions are monitored and processed by card network companies such as Visa and Mastercard.
For every credit/debit card transaction, the payment request from the merchant’s website is sent to the payment processor (bank, gateway, aggregator, or other payment processing service provider).
The payment processor will then send the payment details to the card networks to verify the transaction. Once approved, the details will be sent to the issuing bank, which will deduct your money.
Once the amount is debited, the information will flow in the reverse flow from the issuing bank to the card network companies, to the payment processors, and then to the merchant.
Thus, for a credit card transaction to happen, you need multiple data strings to be shared through various networks and players.
Hence, a banking API was required to streamline payment processing, card issuance, card management, and PIN generation.
The card issuance APIs facilitate easy integration with various players and customer details, making their payment experience smoother, safer, and faster.
Below are various card issuance APIs and their use cases.
Types of Card Issuance APIs
For any customer, the credit card issuance process comprises four main phases: issuing a card, generating a card PIN, making a payment, and managing the card. The card issuance APIs are also available as four distinct banking APIs, each based on one of these primary phases. However, more APIs are constantly being developed in the market.
Digital Card Issuance APIs
The card issuance APIs help companies seamlessly integrate customer details when issuing a credit card. Various fintech companies use these APIs to give business or personal credit cards. Let’s see how this happens.
- You want to get a new credit card and downloaded an application from a fintech company that issues cards, such as Slice.
- You will be asked to create your account on Slice because they will need your personal information from banks and other financial institutions.
- Slice will request a card issuance API provider to fetch your details.
- The API provider will integrate with banks and other parties to transfer your details from them to Slice’s app on your phone.
- Once the integration is done, Slice will issue a credit card to you within seconds.
Thus, card issuance APIs will ensure smooth customer onboarding and a hassle-free, safe, and quick credit card issuance.
Card PIN APIs
These APIs help customers generate, verify, and change their credit card PINs through a self-service portal or a call. Earlier, the card PINs used to come in an envelope, but that method had a risk of card theft. Then the PIN was generated using ATMs, but that required special efforts from us.
The card PIN APIs make the PIN generation, verification, and modification process seamless, as it is handled through an automated call or a self-service portal. Using such APIs, you can set your PIN within minutes.
Let’s discuss how card PIN APIs work:
- You request that your PIN be generated through an application on your phone.
- The phone app will then connect with the API provider and fetch your card details to attach your PIN.
- The API provider will send a request to share details with the card-issuing company.
- Once your card details and other authentication are complete, you can set your PIN within seconds using the card PIN APIs.
Card Payment APIs
This API enables smooth integration between the TPP and the card network companies to authenticate and process payment transactions. The advantage of using the card payment APIs is that you can process payments faster without carrying a card or entering card details.
Credit/debit card payments can be cumbersome when you have to enter every detail, including the 16-digit number, expiry date, name, and CVV. The card payment APIs enable third-party service providers to quickly fetch your details and process your payment after authentication.
The card payment APIs connect with multiple players – card payment processors, card network companies, TPPs, and card issuing companies. But how does a payment transaction get completed using APIs? Let’s learn how card payment APIs work.
- You initiated a payment transaction from your credit card app on your phone.
- The merchant who requested payment from you will send a request to the card payment API provider to gain access to your card details.
- The API provider will connect with multiple players to fetch your details
- The card issuing company, e.g., Slice
- The payment processor, e.g., CC Avenue
- Card network, e.g., Mastercard
- Once the card details are verified and the payment is authenticated, the API provider will send it to the merchant.
- The merchant will get the payment upon successful integration and validation.
All this while you were sipping a cup of coffee, meaning the entire payment transaction took place within a few seconds. The card payment API can connect to multiple software programs and generate a single data string, which is highly secure.
Card Management APIs
When you use a smart credit card, you expect personalization or customizable features. And the card management APIs make customization easier for you. The TPPs offering physical and virtual credit cards incorporate card management APIs to allow customers to change card settings.
A typical credit card setting will include the following:
- Change of card limit
- Blocking a card
- Blocking a specific merchant
- Blocking a payment type such as online, overseas, ATM, etc
- Set merchant limits
The card management APIs are widely used by TPPs that develop and issue credit cards for businesses and customers. These APIs seamlessly integrate with applications and enable your cardholders to change settings as they wish.
The benefit of Card Management APIs to the Businesses
- This feature primarily benefits businesses, allowing them to issue company credit cards to employees and set customizable card settings by position to support different card limits for different employee categories.
- Moreover, it helps you manage your employees’ expenses by allowing you to block, increase, or decrease card limits seamlessly.
- It also benefits organizations by restricting specific payment types, such as ATM, overseas, or online payments.
Thus, the card issuance APIs serve multiple purposes, making your credit card experience hassle-free. While different banking APIs enable various innovative features on a single credit card, selecting an API provider that can streamline the integration of multiple APIs into a single platform is crucial.
Now, let us learn about our next banking API – KYC APIs. KYC APIs are not just banking APIs, as they serve identity verification needs for various stakeholders. Hence, these APIs have multiple uses beyond serving as banking APIs.
KYC APIs
Know Your Customers (KYC) procedures are essential for complying with Anti-Money Laundering (AML) laws. Every financial institution and financial services company must comply with KYC requirements to assess a customer’s risk profile.
It essentially requires the assessment of the following three aspects:
- Identity verification: KYC norms require companies and banks to authenticate that the customer is the same person shown on the identity proof.
- Financial activities: they are also required to assess the financial transactions, mainly to understand customers’ borrowing capacity.
- Risk profile: the customer’s risk profile is also assessed and marked as ‘low,’ ‘medium,’ or ‘highly risky’ based on their regularity in the payments of monthly bills, repayment of the debt, and other obligations such as credit card dues.
Thus, KYC procedures are comprehensive, and KYC APIs help TPPs perform them faster and more conveniently.
KYC APIs allow TPPs to connect to various software programs that store customer information, verify customers’ identities, and perform risk analysis of customers’ financial transactions based on the statement details fetched.
Earlier, KYC procedures were manual and required a lot of time for consumers before onboarding. After the introduction of KYC APIs, many fintech companies have developed innovative KYC solutions that offer a suite of customer identity verification and risk assessment for customer profiles.
With c-KYC, advanced banking APIs can integrate seamlessly with other applications and access customer databases for identity verification. That can save a lot of time compared to doing paperwork and manually verifying IDs.
Let’s learn about the various types of KYC APIs, making the banking experience hassle-free for users.
Types of KYC APIs
Different KYC APIs serve different purposes: a customer identification API helps verify consumers’ IDs more quickly, while ongoing monitoring APIs allow TPPs to continuously monitor customers’ financial activities in the background.
Customer Identification APIs
As the name suggests, customer identification APIs help fintech and other financial services companies verify customers’ identities before onboarding. These banking APIs connect to the central database for ID verification.
When you initiate a request to open an account with a financial services company, the company will approach a KYC API provider and fetch your KYC details within seconds.
Moreover, suppose your KYC verification has already been completed with another company. In that case, the central database will have the records, and the TPP company you approached can use the exact details to close your KYC verification file.
Due Diligence APIs
This KYC API enables companies to perform due diligence quickly by connecting to software that supports customer due diligence to ensure the trustworthiness of potential customers.
But what is customer due diligence (CDD), and how does it work? Before we understand the due diligence API, let’s know the due diligence process.
Financial services companies must perform CDD to verify the identity of potential customers and protect them against fake customer profiles, terrorists, or fraudsters. The CDD process has three types, performing different risk analysis procedures as follows:
Simplified Due Diligence
When a potential customer poses a lower risk of money laundering or terrorist financing, companies are not required to perform a full CDD, and such accounts are often called low-value accounts.
Basic Due Diligence
This is essential due diligence, where companies gather information about customers to verify the authenticity of transactions and assess the risks each customer may pose. At this stage, the companies can identify customers with ‘low,’ ‘medium,’ and ‘high’ levels of risk.
Enhanced Due Diligence
After determining the level of customer profiles, enhanced due diligence is conducted for customers with ‘high’ risk levels. At this level, companies undergo additional due diligence to mitigate the higher risks associated with their customers.
Thus, the due diligence APIs incorporate all three levels of due diligence procedures and integrate them into a single platform to deliver faster results for customer due diligence.
When financial services companies approach the due diligence banking API provider to perform CDD for their customers, the API provider will request the various authorized bodies, including banks and government records, to fetch customer details.
Once the details are smoothly derived, the due diligence banking APIs will enable the CDD procedure and, based on a set algorithm, generate results as ‘low,’ ‘medium,’ or ‘high’ risk profiles. This entire procedure is done quickly and without any data leakage.
Ongoing Monitoring APIs
In every KYC procedure, once the initial KYC verification is complete before onboarding a customer, the only part that remains constant is ongoing monitoring. The concept of continuing monitoring involves reviewing his financial activities after onboarding.
It is crucial for financial services companies to continually review and assess their customers’ activities to promptly mitigate associated risks. If the customer engages in any activities indicating terrorist funding, crime, fraud, or political exposure, the necessary steps are taken promptly.
Earlier, the ongoing monitoring process required a dedicated team to assess risk profiles and perform timely CDDs for their existing customers. After introducing the ongoing monitoring APIs, the process has become faster, safer, and easier to perform.
Financial services companies will need to engage an ongoing monitoring API provider and enable the feature on their websites or mobile applications. When a customer is onboarded, these APIs are automatically activated, and the request to continuously monitor customer activities is sent to the API provider.
The banking APIs provider will continuously fetch customer activity details from various platforms and bodies to ensure the customer’s risk profile remains within acceptable limits.
Thus, the KYC APIs offer a suite of verification and monitoring procedures to help companies meet the AML compliance requirements smoothly.
Let’s now understand what acquiring APIs is and how they work.
Acquiring APIs
These banking APIs are for businesses that sell their products or services online through a website or a mobile application. The acquiring APIs integrate merchants with various payment options providers to offer their customers a seamless payment checkout experience.
In simple terms, acquiring APIs helps businesses get paid. Your customers would want a secure, fast, and hassle-free shopping and payment experience where they do not need to leave your website, but stay on the same page and finish checkout.
Acquiring APIs helps you incorporate a range of payment method providers into your website. When you collaborate with a third party to handle your payments, customers may change their minds before making a payment to a company that is not yours.
Hence, you must be careful while selecting a payment gateway – have an in-house or hire a third party – since your decision will affect the purchase behavior of your customers.
Types of Acquiring APIs
As the acquiring banking APIs are for merchants and similar business owners, their categories cater to different purposes. They are categorized into card acquiring APIs and payment gateway APIs.
Card Acquiring API
The card-acquiring API is a banking API that helps your business accept credit and debit card payments hassle-free. Large merchant websites often experience downtime in card payment processing due to high card transaction volume.
Such downtime may discourage your customers from buying on your website, and hence, card-acquiring APIs can solve this problem by enabling a smooth integration for card payment processing.
Benefits of Card Acquiring APIs:
- You can interact with your customers since the card acquiring banking APIs only allow you to integrate card payment processes on your web page.
- Your customers will have a seamless and secure payment experience.
- You can handle multiple large-volume card transactions on a single platform.
Hence, the card-acquiring APIs help you get paid while also offering your customers a hassle-free, convenient shopping experience without leaving your website.
Payment Gateway API
This type of acquiring APIs helps businesses successfully incorporate a payment system that will allow them to receive payments from various payment networks. In other words, it is a common interface that lets you easily communicate with various payment processors to deliver a seamless customer checkout experience.
Payment gateway API, allowing you to develop your website’s payment checkout page so your customers can make payments without leaving your website. These banking APIs perform specific essential tasks to process the payment:
When your customer proceeds to checkout, the payment gateway API will:
- Encrypt the data set and send the request to the payment network to verify the details.
- Authorize the payment details based on the authenticity of the details entered.
- Pass the order confirmation message as either ‘accept’ or ‘reject’ based on the payment network’s approval.
Let’s understand the payment process with the help of an example:
- Your customer places an order and hits ‘proceed to checkout’ on your webpage.
- The customer will then select a preferred payment method (credit/ debit card, net banking, etc.) and pay.
- Now, you will capture the details and send them to the payment gateway API to connect to the payment network and verify and authorize the payments.
- The payment gateway API will collect the resulting details (accept or deny the payment) and send them to you.
- You will then process the payment and get paid.
The entire process is completed in seconds, without you or your customers having to wait long.
Lending APIs
When you apply for a loan in the bank, as a first step, the bank would run a KYC and due diligence check to understand your financial activities and verify your identity. Raising funds, acquiring loans, and attaining desired interest rates have been crucial in the lending sector.
There has been a huge credit gap in the MSME (Micro, Small, and Medium Enterprises) sector. Various fintech companies have introduced multiple solutions, including BNPL, POS lending, small-business loans, and instant loans.
The lending banking APIs have disrupted the lending segment of the banking industry by providing fintech companies with relevant data and information processing, easing identity verification, credit history checks, sanctions screening, and loan disbursements.
Why Do We Need Lending APIs?
- It enables financial inclusion because it is available anywhere and integrates smoothly with banking software or applications.
- From ID verification to loan disbursement, the process runs seamlessly and faster than at traditional financial institutions.
- Lending APIs help identify the right loan or credit facility for each customer based on their needs and borrowing capacity.
- These APIs provide real-time updates on cash flow, installment reminders, and notifications for each transaction.
- It also transforms how credit facilities are offered and consumed by adding embedded finance products such as BNPL, POS lending, and micro and instant loans.
Thus, lending APIs can streamline the entire lending cycle. The lending cycle typically has four components:
- Customer Onboarding
- Credit Underwriting
- Sanction of a Loan
- Disbursement of a Loan Amount
For each element, there are separate lending banking APIs that have revolutionized the credit market worldwide. Let’s dive deeper into these APIs.
Types of Lending APIs
Since the four lending APIs cover the entire lending cycle, they are used together to complete a single lending transaction. In the case of the other banking APIs, specific APIs can be used individually as separate APIs.
Onboarding Verification APIs
Under a traditional method, the customer onboarding process would start by collecting KYC documents and verifying them with the original identity cards. The next step would be to perform due diligence, which would involve cumbersome procedures to review the borrower’s financial activities and generate additional paperwork.
However, thanks to the onboarding verification banking APIs, the lending process starts with a smooth customer onboarding experience, where KYC verification and customer due diligence are completed in a fraction of the time.
These APIs help integrate with software and computer programs that store customers’ information, e.g., government databases and banks. The API will fetch the customers’ details from this software, and the TPP offering lending services can use the information to verify the customer’s identity and review their financial activities to understand their risk profile.
Based on the level of risk involved in lending to the borrower, the company will adjust its interest rates, e.g., charging higher interest rates for highly risky customers.
Credit Underwriting APIs
In a typical lending organization, the credit underwriting team would work to frame the most suitable loans for customers based on their risk profile and the amount requested.
However, the credit underwriting banking APIs perform this task digitally by integrating with customers’ information from various credit rating agencies (e.g., CIBIL) and fetching relevant information for the lender, so they can articulate the best loan terms for customers using predefined algorithms and data analysis.
Loan Sanction APIs
Once the credit underwriting team specifies the loan conditions, the loan sanction department prepares a formal document, makes any necessary edits, and obtains the borrower’s signature if both agree to the written conditions.
However, the loan sanction APIs do it securely, faster, and digitally, using the customer’s integrated information to prepare a loan sanction letter.
The loan sanction banking APIs help prepare the sanction letter digitally and get it electronically signed by the borrower. These APIs also record the amount sanctioned and the amount already provided to the customer.
Loan Disbursement APIs
The loan disbursement department typically ensures the loan amount is disbursed correctly to the borrower. If the borrower defaults in repayment, further disbursals are put on hold. Moreover, based on ongoing monitoring of the borrowers’ financial activities, the disbursements may be adjusted.
The loan disbursement banking APIs help streamline borrower information, enabling the lender to make disbursement decisions. The APIs integrate the borrowers’ repayment behavior smoothly, and their ongoing monitoring analysis is also integrated into the lender’s system.
It helps the lenders disburse the right amount of loans to their borrowers. These APIs also allow for maintaining a borrower’s account as to how much is disbursed, how much is repaid, and how much is pending as principal and interest.
The loan disbursement cycle is better understood with an example. Here’s an illustration of how lending APIs work:
- A borrower will request that the TPP (lender) lend a certain amount of money for business or personal purposes.
- The TPP will enable its onboarding verification API to run a background check and perform KYC verification and due diligence for the potential borrower.
- Once the borrower’s risk profile is generated, the credit underwriting APIs will integrate the borrower’s loan terms and prepare a loan sheet proposing various terms, including interest rates.
- As the borrower selects the best suitable loan offer, the loan sanction APIs will integrate their details into a formal loan agreement and send it to the borrower for e-signature.
- Once the customer signs the document electronically, the loan disbursal banking APIs will deposit the loan amount in the customer’s bank account or m-wallet. At the same time, continue monitoring the borrower.
Thus, these lending APIs work together, from opening a customer’s loan account to disbursing the loan at the agreed-upon terms, to complete a faster, safer lending cycle.
That completes various banking APIs and how they work. As API aggregators, businesses perform multiple tasks to cater to different customer needs. However, they face many issues while delivering the required APIs to their customers.
How the UAE Protects the Human Element
While 2026 is highly automated, the UAE’s framework recognizes that technology must serve people. This is built on Four Strategic Pillars:
- API Strategy: A clear, documented blueprint for how the data will be used and the benefits to the end-user.
- Human Efforts: Recognizing that developers and security researchers are the brains behind the immune system of the API.
- Technological Immunity: Automating security protocols and documentation to save time and prevent human error in data transmission.
- Operating Framework: A cohesive model that ensures a bank’s internal strategy aligns with national regulatory goals.
Overcoming the 2026 Challenges for Banking APIs
The primary challenge in 2026 remains Data Liability. If a fintech app experiences a breach, who is responsible, the app or the bank that shared the data? In the UAE, this is addressed through explicit Consent Management dashboards, where every resident can see exactly which apps have access to their data and revoke that access with one click.
The Path to 2030
The UAE’s open banking market is projected to reach $19.2 billion by the end of 2031. Through a combination of government mandate and private innovation, the Emirates has created a financial ecosystem where banking is no longer a place you go, but a service that is seamlessly integrated into your digital life.
For the UAE Fintechvibes community, the message is clear: the API era is not coming, it is here, and it is the foundation of the next decade of prosperity.
