Workarounds

  1. 95% success Add the header to the request: in curl, use `-H 'X-Request-Id: abc123'`; in Python requests, use `headers={'X-Request-Id': 'abc123'}`. 
    Add the header to the request: in curl, use `-H 'X-Request-Id: abc123'`; in Python requests, use `headers={'X-Request-Id': 'abc123'}`.
  2. 90% success Check the API documentation for a list of all required headers and their expected values (e.g., length, format).

中文步骤

  1. Add the header to the request: in curl, use `-H 'X-Request-Id: abc123'`; in Python requests, use `headers={'X-Request-Id': 'abc123'}`.
  2. Check the API documentation for a list of all required headers and their expected values (e.g., length, format).

Dead Ends

Common approaches that don't work:

  1. 80% fail

    The server may validate the header's format or content, not just its presence.

  2. 100% fail

    Headers are request-specific; response headers are ignored.
