Workarounds

  1. 98% success Add the missing query parameter to the URL. For example, change /api/items to /api/items?limit=10. In JavaScript: fetch('/api/items?limit=' + limit). In Python requests: requests.get('/api/items', params={'limit': 10})

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The server parses query parameters from the URL, not headers.

  2. 95% fail

    GET requests typically do not have a body; the server expects the parameter in the URL.

  3. 85% fail

    Parameter names are case-sensitive and must match exactly.
