401 Unauthorized
Authentication is required and missing or invalid.
What it means
401 means the request requires authentication. You didn't send credentials, or the token/API key is invalid or expired. Add an Authorization header (e.g. Bearer token) and try again.
401 vs 403
401 = you're not authenticated (who are you?). 403 = you're authenticated but not allowed to do this (what are you allowed to do?).
Test your API and see if the issue is resolved.
