User cannot authorize application because it is UNCERTIFIED
We have done the Adobe EchoSign integration with our Web application using EchoSign Oauth API.
From application our users will be sending the document for signature and final agreement we would like to store in our system. We have done the integration and tested using developer account and everything is working fine.
But when we use some other account then we are getting below error:
User cannot authorize application because it is UNCERTIFIED
Please suggest what is needed to resolve this issue. Do I have to purchase some paid account for this?
