Can you remember the last time you visited a brick-and-mortar bank? Neither can we. Chances are that the majority of your banking, stock trading, peer-to-peer payments, and cryptocurrency activity is now completed through an app or website.
Financial technology, commonly known as fintech, is a booming industry that has already transformed how people around the world manage their money, from personal financing to enterprise-grade accounting. According to BalancingEverything, the fintech industry is expected to reach $310 billion by 2022. Driving the industry is a widespread global adoption of such technologies. While North America has the most fintech startups (recent statistics suggest upwards of 9,000), the APAC region boasts some of the highest user adoption rates thanks to several large fintech global leaders, including India’s ecommerce payment system Paytm and Indonesia’s GoJek.
Today’s fintech users have high expectations when it comes to their apps, including payment processing, unparalleled security, fraud prevention, real-time stock updates, instant customer service or fintech chatbots with advanced chat features, and social media features such as commenting, activity feeds, and notification feeds.
Rather than build this advanced functionality from the ground up, developers should consider integrating these top fintech APIs — which include several different types of APIs — into their products.

Whether it be paying your friend back for dinner or purchasing an item online from your favorite ecommerce site, many users interact with payment processing platforms daily to chat with knowledgeable salespeople or sellers about a specific product, or to verify that their purchase is on its way to their house.
