Acumatica eSign integration with Adobe Sign - Unable to authorize access because the client configur
I am following this guide to integrate Adobe Sign with Acumatica https://github.com/Acumatica/Acumatica-eSign
Authenticating API URL is https://secure.na3.echosign.com
However when I do a test connect, I get the following error
Unable to authorize access because the client configuration is invalid: invalid_request
I am unable to move further. Can someone help me with this? I have set my Redirect URI correctly in Config OAuth and set up the Scopes as described in the document.
Thanks
Markie
