HTTP status code best practices

Use consistent status code semantics across API design and runtime behavior.

  • Align each endpoint with a documented set of expected status codes.
  • Distinguish retryable vs non-retryable errors in client logic.
  • Log both numeric code and reason phrase for faster debugging.
