How fintech API works, its benefits, top use cases among fintech startups, and their future

4 min readOct 12, 2021

Talking about fintech transformation, we can’t overlook fintech Application Programming Interfaces (APIs) and the role they are playing in the massive effects when fintech solutions change the finance industry.

How Does API Work?

In fintech, APIs serve as mediators between different pieces of software, enabling them to safely connect and exchange data.

APIs also contain a set of functions that can be tailored for different purposes, enabling developers to use them as building blocks for new apps.

The Benefits of Using Fintech APIs With Application Examples

For businesses, the use of fintech API is beneficial in a number of ways:

1. Third-party integrations

While users are continuously demanding new services, adding them often involves expenses. Making various services available through third-party integrations conducted via APIs keeps customers happy while ensuring cost-efficiency.

2. Security and compliance

In support of Open Banking, many countries introduced regulations requiring financial companies to provide third parties with access to customers’ data. Fintech APIs offer companies the means of working with sensitive data and opening it to third parties while keeping it secure. For example, APIs are capable of letting users control which apps may access their bank accounts, instead of logging into a bank account to grant permissions or letting the app learn their usernames and passwords.

3. Fast time-to-market

By using APIs companies can quickly add new app features and benefit from the accelerated launch of new products and services. They can also tailor API functions to their specific purposes and reuse some of the application components, which saves time and cuts the costs of fintech software development.

4. Cross-platform availability

Due to APIs, customers’ mobile, desktop, and wearable app versions can sync easily which accounts for seamless customer experience and better customer relationships.

Top Use Cases of Fintech APIs

To be more specific, let’s now take a closer look at how financial companies are leveraging APIs to achieve cost-efficiency, fast time-to-market, and customer satisfaction. These top use cases for fintech APIs offer some vivid examples.

Digital banking

In banking, APIs are used to expand the portfolio of services. Authentication, payment processing, analytics, account information, and loyalty programs are some of the main domains for the use of fintech APIs. For example, HDFC allows RazorpayX API to access its services and perform money transfers and balance checks.

Lending and Mortgages

The use of APIs enables lenders to accelerate loan application processes and achieve greater customer satisfaction. Eli Mae, for example, is using APIs to accelerate the processing of loan applications. Another example is PayMyParents that utilizes an API for payments processing.

Verification engines

Formerly, the verification of information submitted by users of financial services required the work of several staff members. With the help of APIs, fintechs like Zillow are now doing it faster, by automatically contacting other electronic systems for verifications.

Opening accounts

This used to be a lengthy procedure, which required a physical visit to a bank. Companies like Meridian Link offer fintech APIs that are now enabling clients to easily open accounts online.

Aggregating data

To estimate the customers’ financial situation, companies have to aggregate data from all the clients’ accounts and view it in one place. Venmo, for instance, uses Plaid APIs to enable the pay-with-your-phone option.

Financial Market Data

Companies can also use APIs to broadcast financial data from multiple sources in real-time. For example, Thompson Reuters API enables companies to bring customers the most precise and recent financial market data to power their legal and commercial decisions.
