Connecting digital financial services to a wider digital world

An application programming interface (API) allows one software program to “talk” with another. APIs enable a wide range of innovative products and services that millions of people use every day. For instance, APIs are what make it possible for ride-hailing apps to leverage other companies’ mapping and payments systems. Sometimes companies create an API for a single or small number of partners. When a financial services provider “opens” its APIs, it makes them widely available for other companies to consume. For example, a digital payments provider could open APIs to enable a whole range of e-commerce companies to plug seamlessly into its payments system. If done right, open APIs generate revenue for the provider and accelerate innovation in the marketplace that benefits low-income customers, as explained in the short videos below.
