HTTP 401
invalid_api_keyInvalid API key
A `gid_` API key was supplied but does not match any active credential.
Likely causes
- The key was revoked, rotated, or belongs to a different environment.
- The key value was truncated or has a stray whitespace/newline.
How to fix
- Confirm the key is active in Profile → API Keys and copy it again (keys are shown once at creation).
- Check you are using a live key against production and a `gid_test_` key against test data.
