Zoho CRM Custom Connections

Zoho CRM Custom Connections

Hey Everyone,

I'm working on adding a connection as a custom service in CRM. I have all of the required credentials for Oauth2.0, but I'm having trouble with authentication, though it is working for me in my Postman client. When I insert all of my credentials, I am getting the following error:



This error isn't giving me any indication of what is going wrong with the authentication.

I am not sure which parameters I should and shouldn't include in the URLs (include scope & client_id in the query string?) Here are some details on the connection. I would love some direction on how to structure all of this in the Custom Service tool in Zoho CRM.
  1. The "Authorize URL" contains the following parameters:
    1. client_id=<MY_CLIENT_ID>
    2. response_type=code
    3. redirect_uri=<MY_REDIRECT_URI>
    4. scope=<MY_SCOPES>
      1. I am not able to put the scopes in here, since that puts spaces in the URL
      2. Does the "Scope" field under "Connection Details" insert the scopes into the "Authorize URL"?
  1. The "Access Token URL" needs the following in the POST request:
    1. grant_type="authorization_code"
    2. client_id=<MY_CLIENT_ID>
    3. client_secret=<MY_CLIENT_SECRET>
    4. redirect_uri=<MY_REDIRECT_URI>
    5. code=<MY_CODE> (from authorization endpoint)

Enabling this connection would be extremely beneficial. I'd love to hear your thoughts and opinions on this!

Thanks,
