## What the Esign Download Document API does

Esign Download Document retrieves the signed documents once execution is complete, returning them in Base64 form for storage or onward delivery.

The signed document is the artefact that matters. It carries the signature certificates that make it legally enforceable, so retrieving and archiving it properly is the step that gives the whole flow its value.
