How To Build Restful Api?

How do I create a RESTful API?

Here are some essential rules for ensuring security during the backend development:

1. Use HTTPS. A secure REST API should only provide HTTPS endpoints.
2. Add a timestamp to HTTP requests.
3. Restrict HTTP methods.
4. Consider input validation.
5. Use OAuth.
6. Don’t expose sensitive data in URLs.
7. Perform security checks.

2. The easiest way to start using an API is by finding an HTTP client online, like REST-Client, Postman, or Paw.

The developer creates the API on the server and allows the client to talk to it. REST determines how the API looks like. It stands for “Representational State Transfer”.

Is RESTful stateless or stateful?

As per the REST architecture, a RESTful Web Service should not keep a client state on the server. This restriction is called Statelessness. It is the responsibility of the client to pass its context to the server and then the server can store this context to process the client’s further request.
