OAuth invalid_request
I use a free account for testing and have followed various manuals
(https://developerwind.eu1.adobesign.com/public/static/oauthDoc.jsp#oauthTokenExchange)
to get my authorization code but I always get invalid_request.
My application is the following:

And the url that I am using for authentication is the following: https: //secure.adobesign.com/public/oauth? redirect_uri = https: //www.google.com/&response_type=code&client_id=******- xu8 & scope = user_login: self
Thanks for your help.
