Connect Gumloop to Adobe Sign

Hi everyone, 

This is my first post and I'm looking forward to establishing an Adobe Sign connect with a little help from the community. My goal is to use the Adobe server to server API to connect my Gumloop profile to my Adobe Sign and send out automated signature letters. Does anyone have experience setting this up or setting up something similar that wouldn't mind offering some guidance? I'm using Postman right now to establish the initial connection.
