Deliverable events – SignatureAPI Docs

Deliverable events notify you when SignatureAPI generates the final signed document (the deliverable), or when generation fails. This page explains each event type, when it fires, and the additional data included in the payload.

deliverable.generated

Fires when a deliverable is successfully generated and ready for download.

The data.url property contains a pre-signed download link. This URL expires after 1 hour. If it has expired, call the Retrieve Deliverable endpoint to get a fresh link.

    }

deliverable.failed

Fires when deliverable generation fails. The deliverable status is set to failed.

The data.detail property contains a human-readable explanation of the failure.

Deliverable failures are rare. SignatureAPI support is notified automatically when this event fires.
