Get Document Download URL
Beta. The Documents API is in beta and its contract may change.
Returns an expiring, signed URL from which the document file can be downloaded, along with its filename, MIME type and size. This is a separate call from Get Document By Id because the URL expires within minutes while the document metadata stays cacheable for hours, and because downloading a signed W-4 warrants its own permission and its own audit event.

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
