n8n errors / Auth

Authorization failed - please check your credentials

platform: n8n / category: Auth

Cause

The credential attached to the HTTP Request node is missing, expired, or not sent in the header format the API requires.

Fix

Confirm the token/key is still valid with the provider. Verify the node's authentication type matches what the API expects (Header Auth, Bearer, Basic). If the credential test passes but execution fails, inject the header manually in the Headers section to bypass the credential layer. Check the raw response body for a more specific message.
