Currently, no functionality exists to allow the developer to download a document/file (signed or otherwise) in the existing OOTB SmartObjects created from an Assuresign service instance (NOP or Cloud).
Similar functionality exists for DocuSign integration, and it would be great to see similar with Assuresign.
This imo is critical functionality. It is possible from REST service I used previously before the OOTB integration shipped but it would be very cool if this was added to the OOTB functionality especially since the OOTB DocuSign integration can already do that.
