Custom Connectors - troubleshoot Oauth 2.0 - Generic Oauth 2

(0) ShareShare
ReportReport
Posted on by 20

I'm trying to create a custom connector based on oauth2 to a Saas solution (https://canvas.instructure.com/doc/api/file.oauth.html)

 

I'm able to create a connection to allow the connector to connect on my behalf and I have access to the API action I want to perform.

 

But when testing the custom connector, I receive a 401. In the test request I see a bearer token send to https://europe-001.azure-apim.net/apim/canvas.20flow.5fc4....

 

{
  "Authorization": "Bearer eyJ..."
}

 

The error message is:

{
  "errors": [
    {
      "message": "Invalid access token."
    }
  ]
}

 

Can I troubleshoot this further without having access to the Flow or SaaS backend?

    Hi @BartVermeersch,

     

    Have you created the connection successfully?

    The error message means that the access token you are using is invalid. Please try to verify access token and try again.

    Please check the following doc for more details:

    https://docs.apigee.com/api-platform/reference/policies/oauth-http-status-code-reference#verifyaccesstoken-invalidaccesstoken

    https://www.oauth.com/oauth2-servers/access-tokens/access-token-response/

     

    Best regards,

    Mabel

    Hi Mabel, thanks!

     

    We found the solution. The base url was still referring to a test environment while all other url's were updated to production url's..
