Application Programming Interface (API)

An application programming interface is a way for two or more computer programs or components to communicate with each other. It is a type of software interface, offering a service to other pieces of software.

Some API implementations:

• REST
• GraphQL
• gRPC

REST sits on top of HTTP.
