REST API

REST stands for Representational state transfer. It formalize an interface to access resources that are physically separated.

REST defines four interface constraints:

• Identification of resources

• Manipulation of resources

• Self-descriptive messages

• Hypermedia as the engine of application state

REST APIs are documented with OpenAPI (aka, swagger).
