Shared Agreement/Document Library

Hello,

I am integrating the Adobe Sign API into one of our internal applications. We have a department that needs the signing services but also needs to be able to view and manage all of the documents that are sent by each other. I thought I would be able to achieve this functionality by creating Groups in Adobe Sign but I was unsuccesful. Is there a different way to achieve this? Would the best bet be to send all of the documents from 1 account and then have every user logged into that account?

I am new to the Adobe. I haven't been able to find anything in the documentation that might point me in the right direction but maybe someone here can enlighten me. TYIA!
