AdobeSign: Automated Document Sending

Hey folks,

I am stuck trying to discover the proper workflow for what I am trying to achieve:

I need to have a nightly job that uses the API to send documents with no human interaction.

I have a manual web page setup on a public facing server that does the OATH2, gets the token, sends the requests, and retrieves the agreementId.

However, I can not get this to work as a nightly job, as when the script (behind firewalls) calls the public script, instead of getting the agreementID passed back,

it is passing back the HTML for the Adobe login screen.

What is the proper workflow for using AdobeSign in a nightly, automated fashion?

Thanks,

David
