Unclaimed Draft

Create Embedded Unclaimed Draft

Creates a new Draft that can be claimed and used in an embedded iFrame. The first authenticated user to access the URL will claim the Draft and will be shown the "Request signature" page with the Draft loaded. Subsequent access to the claim URL will result in a 404. For this embedded endpoint the requester_email_address parameter is required.

NOTE: Embedded unclaimed drafts can only be accessed in embedded iFrames whereas normal drafts can be used and accessed on Dropbox Sign.
