Instance Method Details

#id ⇒ String

Generates a unique SHA-256 hash to identify the request.

The hash is constructed using the request method, full path, idempotency key, authorization header, and the request body (if available and rewindable).

This ensures that requests with identical content produce the same fingerprint, supporting idempotency while preventing accidental collisions between different clients.

Returns:

  • (String) —

    A SHA-256 hexadecimal digest representing the request fingerprint.
