We are using Signer Attachment tabs in a multi-recipient envelope. After completion, we can retrieve documents using Envelopes API, but there is no clear way to determine which signer uploaded which attachment. What is the recommended approach?

Hi ​@sangeerth999,

When using Signer Attachments, the uploaded attachment PDFs do not contain a field indicating which recipient uploaded them. The recommended approach is to correlate each attachment back to the corresponding signerAttachment tab.

A common implementation pattern is:

  1. Assign each signerAttachment tab a unique, meaningful name and associate it with a specific recipient.

  2. After the envelope is completed, call:
    GET /accounts/{accountId}/envelopes/{envelopeId}/recipients/{recipientId}/tabs

    This returns the recipient's tabs, including their signerAttachmentTabs, along with the associated tabId values.

  3. Call:
    GET /accounts/{accountId}/envelopes/{envelopeId}/documents

    The attachment documents returned include an attachmentTabId property.

  4. Match the document's attachmentTabId to the corresponding signerAttachmentTab tabId, which in turn identifies the associated recipientId.
