    In this blog we will help you understand:
  • What is an API integration?
  • Essential integrations for Fintech products used for:
    • Authentication/ Verification
    • B2B Payments
    • Remittance
    • Billing Payments

      APIs offered by fintech platforms will help you reduce fraud and other financial risks, enhance security, eliminate the paper hassle, enable instant integration with popular accounting platforms and much more.

A weary traveler has arrived at the airport in his hometown. He pulls out his phone and orders a Lyft, which picks him up in just a few minutes. While he is riding home, he decides that he is hungry. He picks up his phone and orders a takeout delivery from his favorite deli. When his food arrives, it has already been paid for, because his payment information is stored in the deli app that is also connected to his bank account.

Later that evening, he receives an alert from his bank, telling him that he has used more than his monthly budgeted amount for dining out. It looks like he will need to “brown bag” it for a while. It also informs him that the stock he had a sell order on has been sold because it reached his price point.

All of these activities are the result of fintech product integrations that make the user experience streamlined and seamless.

Whether legacy financial institutions or new fintech banking solutions, being connected to apps, data, and devices expands services and provides the convenience that today’s consumer demands. The example above demonstrate just a small amount of API integration into fintech ecosystems, but the potential is almost endless, given the number of API’s created in recent years.

If you are planning to develop a new secure fintech product, a mobile banking app or any other financial app, you can utilize a number of existing APIs instead of writing the code from scratch. Not only will you reduce the development timeline this way, but also benefit from the innovative tech stack.

So What is an API Integration?

The Application Programming Interface is a software intermediary that allows two apps to “communicate” with each other and exchange relevant information.

The web is full of API’s all sitting out there. If you are checking the weather, sending an instant message on Facebook or ordering food online, you are interacting with APIs.

Now, programmers can connect multiple applications together and eliminate the need for a user to click through each one separately. The “wall” or gap that existed between these API’s has been eliminated. Thus, one click to the deli took care of ordering and paying both.

Essential API Integrations for Fintech Products

You have a fintech product, perhaps an online banking solution. You want to allow your customers access to all sorts of activity directly through your platform, via mobile or web. Of course, your customers can open an account online, and API’s can let them verify their identities, transfer money to individuals they have in their personal address books, and use any of the credit cards they have stored with you, without the need to enter card details when they shop.
