Client Credentials

The Client Credentials Flow is a part of the OAuth 2.0 framework, designed for machine-to-machine (M2M) communication. It is used when an application needs to authenticate and authorize itself, rather than a user.

How It Works​

  1. Client Authentication: The client application sends its client ID and client secret to the authorization server.
  2. Token Issuance: The authorization server validates the credentials and issues an access token.
  3. API Access: The client uses the access token to authenticate API requests.

Use Cases​

  • Backend-to-Backend Communication: Secure communication between two server-side applications.
  • Service Accounts: Accessing resources on behalf of a service rather than a user.
  • API Authorization: Granting access to APIs that do not require user interaction.

Benefits​

  • Simplicity: No user interaction is required, making it ideal for automated processes.
  • Security: Credentials are securely exchanged between trusted systems.
