What Happened

The API key used to authenticate the request was not recognized.

​
How to Fix

  • Check that the API key is complete and has not been truncated. API keys start with key_test_ or key_live_, and the prefix is part of the key.
  • Ensure the API key is passed in the X-API-Key header, not in the Authorization header or as a query parameter.
  • Verify the key has not been revoked or regenerated in your Dashboard.
  • If you recently created the key, wait a few seconds and try again.
