DocuSignInstall

Summary

Adds a supplemental document to an existing DocuSign envelope, using either base64 content or a binary property from the incoming item. You choose how it is shown to recipients and how much acknowledgment signers must give.

Inputs

• Authentication — JWT (Service Integration) or OAuth2 (User Authorization). Defaults to JWT.
• Envelope ID (required) — ID of the envelope to attach the supplemental document to.
• Document (Base64 or Binary Property) (required) — Base64-encoded document content, or the name of a binary property on the input item. The node's helper resolves it to base64.
• Document Name (required) — File name for the supplemental document. Defaults to supplemental.pdf.
• Display — Modal (a dialog the recipient must acknowledge) or Inline (within the document flow). Defaults to Modal.
• Additional Options — Include in Download (whether the document is part of the combined download, default true). Signer Must Acknowledge (No Interaction, View, or Accept, default View).

Output shape

A single item containing the DocuSign API response for the update to the envelope's documents.

The exact response fields come from the DocuSign API, and the supplementalDoc.js handler body was not visible in the source pack. Invalid envelope IDs or inputs raise an error unless Continue On Fail is enabled.

Examples

Example 1: Attach a PDF disclosure from a previous node's binary output that signers must accept.

Envelope ID from earlier node; Document = binary property name (e.g. data); Document Name = disclosure.pdf; Display = Modal; Signer Must Acknowledge = Accept.

Example 2: Add a reference document that signers can view but that stays out of the final combined download.

Document = base64 string; Display = Inline; Include in Download = false; Signer Must Acknowledge = View.
