Best FinTech APIs – The Ultimate List

November 2022

An Application Programming Interface or API is a powerful tool that makes your digital product even more interesting for current and potential users. We have prepared a list of FinTech APIs you can use, but first, let’s consider what an API actually is and how you can use it.

What are FinTech APIs?

An API is a connector between different applications that lets them safely connect and exchange data. The solution is popular in many industries, but we observe growing popularity in FinTech. Banking software development companies use APIs to enhance customers’ applications. By enabling API, many companies, especially those offering open banking apps, can provide significant value.

Benefits of using FinTech APIs are clear – from enabling third-party integration, ensuring security and compliance, through shorter time-to-market, ending with cross-platform availability. Naturally, you should first browse for API development services providers but in a nutshell, this is how it works – FinTech API broadens your perspective and market chances. 

How can you use FinTech APIs?

First, think of partnerships. Imagine what is missing in your product or how you can benefit by connecting your product with another application. Then, make sure to focus on core functionalities. With the help of your partner, you can create a whole new line of products, promotions, and offerings but ultimately both interconnected applications are what customers value the most. FinTech API can indirectly generate new revenue but it’s your applications that generate loyalty. 

If you’re not sure how to approach the topic, you can also browse the more general category: open banking solutions or check custom open banking development services. Specialists will help you find the right solution and integrate it into your product.

And now, let’s dive into the list.

Strivve owns the trademark on “Top of Wallet” and we provide “Top of Wallet” solutions that 1) protect their card transaction volume (aka card use) and 2) compete for Top of Wallet status and increase usage across their cardholder base, yielding increased card transaction volume in various ways throughout the untimely cardholder journey. Strivve use robotic process automation and machine learning, with 2 issued patents and another in process, to “push provision” any form of payment credential to online retailers and billers alike. Strivve performs these from a “Stripe-like” or “PayPal-like” API platform, embedded within banking applications. However, Strivve transactions are NOT in the “payment transaction” proper like Stripe or PayPal are. Strivve pushes payment credentials (Cards, VCN, Tokens, ACH) to the retailer or biller AHEAD of the next purchase or payment to help enable the friction free card-on-file or stored-payment-method experience cardholders want and expect.
