Software Development Updates

Fintech application programming interfaces (APIs) are known for transforming various financial industries. Financial software development companies adopt these APIs to get new financial services, applications, and business models into the market. To know more about it, let us go through this blog.

1. What are Fintech APIs?

 The term “fintech API” refers to a set of processes that allow applications to connect to the data and services stored on the servers of financial companies or banks. APIs help in accessing data for the parties involved in financial transactions like third-party providers, banks, consumers, and websites. All the popular fintech applications in the market work on APIs that help them with real-time data access. Similarly, in the financial sector, APIs allow third parties to access data with the permission of the client. And this has completely changed the way the financial sector works.

The increase in the dominance of APIs in financial technology has made understanding this technology easier. For this, banks need to collaborate with third parties to expand their services.  Merchants have to make it simple and easy for the clients to pay using their preferred payment option. These things are possible with the help of the fintech APIs. This financial API is utilized by the developers in creating applications for the banking and finance industry and makes services cost-effective & faster.

2. How Does API Work?

APIs act as mediators between different parts of software that are used to exchange data and this is the case in all the fintech solutions. The APIs for fintech applications come with a set of functions that can be customized for various purposes, enabling application developers to use them as building blocks for new software solutions.

FinTech APIs regulate the flow of information and communication between various financial technology platforms and third-party apps. To understand how they function, consider the following:

2.1 Request and Authentication

When a user uses a FinTech app or completes a financial activity, it creates a request. Tokens, keys, or other types of information are often needed for authentication in API banking technologies to confirm the user’s identity and authorization levels.

2.2 Data Retrieval and Processing

The API passes the request to the server or system that processes the FinTech. Examples of this processing include communication with third-party services, such as payment service providers or banks, or doing computations or retrieving databases.

2.3 Data Exchange

A response is sent back over the API by the FinTech system, once the fintech system finishes handling the request and collecting the appropriate data. Any pertinent data, such as financial details or confirmations of transactions, might be included in this response.

2.4 Integration

The receiving mobile app will either integrates that information into a display or add it into another actions.

2.5 Error Handling and Security

APIs in the financial technology sector contain robust error-handling systems to address validation errors, server outages, and erroneous requests. To further ensure the security of private financial data, API banking integration necessitates the use of many security measures, including encryption.

2.6 Continued Monitoring

To fulfill security standards, comply with regulations, and ensure maximum performance, it is vital to continuously monitor API-based banking activity.

3. Types of APIs You Can Use for Fintech App

There is a good probability that an API already exists for the functionality you want to add to your app. Learn more about the various APIs and how they may improve your finance app below.

3.1 Financial Data Aggregators and Providers

Via these application programming interfaces (APIs), third-party programs can have access to users’ monetary data, such as bank financial statements. In addition, some make it possible for third-party applications to provide banking and financial services.

APIs are available from most major financial institutions. For instance, Citibank offers a wide variety of APIs for developers to build apps that connect to their banking services, including account management, bill pay, and security.

The developer website also has a wealth of resources, such as examples and use cases, to help guide developers.

Although reliable and safe, APIs provided by individual banks can only be used for dealings with those banks. Data aggregators such as Plaid are preferable if you value adaptability.

They do the groundwork, including verification and validation, and have access to data from several financial institutions.

Financial data aggregators will certainly become one of the most crucial APIs determining the face of fintech as Open Banking projects are accelerated throughout the world.

3.2 Payment Processors

When it comes to the impression that APIs have on the financial technology industry and the Internet economy as a whole, payment processors stand out as the undisputed frontrunners.

Digital transactions rely on these third parties to acquire, validate, and accept payment. Stripe, PayPal, and MangoPay are just a few examples of popular APIs.

A recent Statista survey found that the payment area was the top-performing fintech sector. This is not unexpected in the least, as payments are required by the vast majority of fintech apps.

To avoid the tedious details of processing payments yourself, a payment processor is essential. Among these are anti-fraud measures, security measures, and foreign exchange.

As a result, this is likely to be the minimum API level required going forward.

3.3 KYC and RegTech Tools

Despite its numerous obstacles, Know Your Customer (KYC) is a crucial practice for regulation in many nations.

Issues with KYC in your app might include longer onboarding times, higher expenses, and security worries.

Rather than having to manually handle identity verification and its various intricacies, you can let KYC tools do all the heavy lifting for you. For instance, ShuftiPro offers video interview KYC and face biometrics to enhance security against fraud and fake recordings.

Some services, such as Alloy’s, use AI and extensive client data to completely automate the Know Your Customer (KYC) process.

By automating formerly manual processes, RegTech is similarly contributing to the development of the compliance landscape. 

There’s little question that in the future of fintech, compliance will be an arduous, time-consuming, and expensive need. However, there are ways to make it more manageable, and APIs for KYC and RegTech are one of those ways.

3.4 Authentication and Authorization Tools

Because of the prevalence of continuous cyberattacks on the financial services industry, security has become an integral aspect of fintech. As it is getting more complex, we need to keep improving our defenses against it.

Fortunately, security APIs exist and can be simply implemented into software. No need to stress over enforcing them on your own when you have these available.

Native technologies, such as Apple’s Biometric Authentication and the Android Biometric Library, are available for usage with biometrics. Moreover, you may increase security by implementing multi-factor authentication (MFA) with tools like the Duo Auth API.

Every part of your software’s ecosystem contributes to its security, thus APIs are limited in their capacity.

3.5 Investment Brokers

Developing programs for dealing in the markets is the most difficult component of developing investing applications, and that also comes with its risks. Several high-quality broker application programming interfaces (APIs) mean you won’t have to start from scratch.

Trading on the customer‘s side, broker APIs are analogous to their human equivalents. 

APIs for brokers can provide a wide variety of services. Some, like Interactive Brokers, provide a comprehensive set of services that enable trading in virtually every market imaginable.

Others, like Polygon.io, exist primarily to provide extensive stock data. The cryptocurrency exchanges that CoinAPI provides access to cryptocurrency exchanges are a great starting point for anybody interested in learning more about cryptocurrencies.

Integrating investment tools into your app is straightforward using broker APIs. As a result, it’s simple to include other types of fintech apps, such as monetary management or electronic banking.
