Soumitra Dutta Oxford-How do I fix authentication errors when connecting external APIs?

Hi, My name is Soumitra Dutta, an Oxford-based entrepreneur & photographer. I’m facing authentication errors while connecting an external API in JetAdmin and can’t seem to figure out the issue.

Has anyone experienced this before? I’d really appreciate it if you could share any suggestions or fixes that worked for you. Thanks!

Before chasing the JetAdmin configuration itself, I’d confirm the credentials work outside it — a quick request with curl or Postman against the same endpoint tells you whether the problem is the API key, its scope, or how JetAdmin is passing it. The usual culprits are a key pasted with stray whitespace, a truncated secret, the wrong auth header format (Bearer vs. a custom scheme), or a token that expired. Also check the exact error code returned: a 401 points at credentials, while a 403 is usually permissions on the external service’s side.
