How token based authentication works in REST API?

How token-based authentication works

1. The client sends their credentials (username and password) to the server.
2. The server authenticates the credentials and generates a token.
3. The server stores the previously generated token in some storage along with the user identifier and an expiration date.

What is OAuth authentication REST API?

Which authentication is best for web API?

OAuth 2.0 is the best choice for identifying personal user accounts and granting proper permissions. In this method, the user logs into a system. That system will then request authentication, usually in the form of a token.

How do I recover my username and password in REST API?

The client must create a POST call and pass the user name, password, and authString in the Request headers using the /x-www-form-urlencoded content type. The AR System server then performs the normal authentication mechanisms to validate the credentials.

Is a Web service the same as an API?

There you have it: an API is an interface that allows you to build on the data and functionality of another application, while a web service is a network-based resource that fulfills a specific task. Yes, there's overlap between the two: all web services are APIs, but not all APIs are web services.
