An authentication error means the request was not authenticated. The API could not confirm who you are, so the request is rejected before any processing.
Every error in this family includes a stable code (for example AUTH-1001). Find that code in the table at the bottom of this article to see exactly which rule was triggered.
Common causes
The bearer token is missing from the request.
The token is expired or invalid.
The authorization header is malformed.
How to fix it
Match the code in your response to the table below.
Include a valid bearer token in the Authorization header.
If the token is expired, refresh it or re-authenticate.
Confirm the header format is correct.
Re-send the request.
