it works in Postman but fails in n8n, the issue is usually subtle configuration differences.

Check the following:

  • Make sure all required headers (especially Authorization and Content-Type) are explicitly defined.
  • Confirm the request body format matches the API expectations (JSON vs form-data vs raw).
  • Verify that credentials are correctly configured inside n8n.

If the API requires specific TLS or certificate handling, ensure your n8n environment allows it.

Sometimes Postman auto-adds headers that n8n does not, so compare both requests carefully.
