Authentication is a critical step in securing API endpoints. Here's a structured workflow for implementing secure API authentication:

  1. Client Request
    A client sends a request to an API endpoint, typically including headers like Authorization with a token.

  2. Token Validation
    The server verifies the token's validity, checking its signature, expiration, and scope.

  3. User Authorization
    Based on the token, the server grants or denies access to specific resources.
