OK, I've got a test of a document from Zapier to being signed by a user on Docusign working. I've got a webhook URI that takes a POST call and returns some fields.
The next step is to get the webhook sending to Zapier. I can't find documentation anywhere as to what the field in the call should be of how to attach a Word document.
Anyone got pointers to the relevant docs or HOWTO?
Ta,
