What is REST API?
REST (Representative State Transfer) is a way to connect two computer systems over the Internet. The REST API is browser and programming language-independent. Any modern browser can be used to run your REST API client, and any programming language can be used to create desktop or mobile REST API applications.
The REST API define a set of rules for developers:
- Client-server: a REST API client (website, desktop or mobile application) should separate from the REST API server (request processor and data storage) so that each part can be developed and scaled independently.
- Stateless: REST API requests must be executed with all the necessary data without assuming the server may have previous REST API client data.
- Layered: the REST API client does not need to know if it communicates with an actual server or an intermediary. Additional scalability and security can be provided by intermediate servers (proxies or load balancers).
- Cacheable: Every REST API response must be cacheable.
