Finance APIs are software that can communicate with financial apps to facilitate data access, payment processing, and transactions. Financial platforms and institutes utilize these APIs to enhance user experience, simplify integration, and enable smooth collaboration between financial partners.

A finance API aims to allow users to access financial information whenever they want with a few clicks. It also enables seamless data sharing between the apps for users, business partners, 3rd-party vendors, and employees. Financial APIs fill the gaps between distinctive apps and synchronize data across different apps. They can connect to legacy financial apps and collect data from them by getting inbound requests. Next, they process the requests, access the requested data, and send the response.
