Acrobat Sign Sandbox connect integration

[marcel_6446]

Is it possible to connect Adobe Acrobat Sign Sandbox accounts to thrid party integrations? When trying to connect I noticed that O-Auth is different than production and can't log in for some reason. I'm the developer of this O-Auth integration and I could change the `authURL` and `tokenURL` in order to make it work.

To make the question more clear, does Adobe Sign Sandbox support the same API calls as production? if not what changes I have to make?
