Leap crm intgration problem with n8n

Questions
1

Hi team,

I’m trying to connect Leap CRM to n8n (v1.88.0) using a valid Bearer token, but I keep encountering the following error:

403 Forbidden - perhaps check your credentials?

The same request with the same token works perfectly in Postman and returns the expected user data, so I’m confident the credentials are correct.

Here’s what I’ve done so far:

  • Verified and regenerated the token multiple times.
  • Reviewed the API documentation for any special requirements or headers.
  • Confirmed the endpoint and method are correct.
  • Tried using both HTTP Request node and credentials-based setup in n8n.

Still, n8n throws the 403 error while Postman works without issue. Could this be related to CORS, user-agent headers, IP restrictions, or any special request formatting required by Leap CRM?

Any guidance or insights would be greatly appreciated! Let me know if I’ve missed anything.

Thanks!
