I am in the process of going live in docusign from my developer account, when making the 20 consecutive calls i used Authorize Code Grant Access Token to get the access token but i am not passing the review and getting error "not using oauth 2.0", what should i do?. i have done this process before but it is the first time getting this error
this is the url i am using to authenticate
the method to pass the review to go live
So, it's enough that you made a single bad call, to make all the other good calls irrelevant.
In other words, maybe you did 20 calls with OAuth 2.0, but then you made (for whatever reason) a call using the old legacy auth (X-DocuSign-Authentication header) and that one will fail your review.
You could start with a new IK and change the IK and run the calls again, or you can contact DocuSign Developer support to try to get you an exception.
