One of the SigningHub roles is called "Editor".  This allows a recipient to edit input fields on a document, but does not require a signature.  Once completed the recipient submits their changes.  The button used in the GUI is called "Submit".

This is the equivalent operation for an editor to submit their changes via an API call.
