Authorization Code Grant error: invalid authentication request

问题

Our attempts at authentication have thus far returned only errors as we try to follow the directions detailed here: https://developers.docusign.com/esign-rest-api/guides/authentication/oauth2-code-grant

When we send this response:

https://account-d.docusign.com/oauth/auth?response_type=code&scope=signature%20impersonation&client_id=3f67330c-2cbf-43f6-9ea5-e295cd646840&redirect_uri=http://138.68.27.51:8080/signCallback#/username

we get an error: "Invalid authentication request: The response type is not supported."

The type is code as described in the Authorization Code Grant document.

Any advice would be greatly appreciated.

Cheers,

If 'code' grant type is returning the 'not supported' error, it's most likely because you've checked the 'This is a mobile app' checkbox for the integrator key. To resolve, log in to DocuSign > Go to Admin > API & Keys > Edit the ikey > Uncheck the mobile app checkbox.

Checking that box disables Code Grant and enables the Implicit Grant workflow (documented here: https://developers.docusign.com/esign-rest-api/guides/authentication/oauth2-implicit)
