Client Credentials Grant
The Client Credentials Grant is a method used in the OAuth 2.0 framework for obtaining access tokens. It is primarily designed for server-to-server communication, where an application (the client) needs to access its own resources without user intervention. In this flow, the client authenticates itself using its credentials, typically a client ID and client secret, to request an access token from the authorization server.
This grant type is commonly used for applications that need to perform tasks on behalf of themselves rather than on behalf of a user. For example, a background service might use the Client Credentials Grant to access APIs securely, ensuring that only authorized applications can interact with the protected resources.
