ZapSign

Overview

This node integrates with the ZapSign API to manage electronic document workflows, including creation, retrieval, updating, sending for signing, cancellation, refusal, downloading, and more. Specifically, the Document - Download operation allows users to download a document by providing its unique token.

Typical use cases include:

• Automating document management in business processes.
• Retrieving signed or unsigned documents for record keeping.
• Integrating document downloads into larger automation workflows.
• Archiving or processing documents after signature completion.

For example, after sending a document for signing, you can use this node's download operation to fetch the completed PDF for storage or further processing.

Properties

Output

The output of the Download operation is a JSON object representing the downloaded document data as returned by the ZapSign API. Typically, this includes metadata about the document and the file content (likely encoded or referenced). The exact structure depends on the API response but generally contains:

• Document metadata (e.g., name, status, timestamps).
• Possibly a URL or base64-encoded content of the document file (PDF or DOCX).
• Other relevant document details as provided by the API.

If the node supports binary data output for the downloaded document (not explicitly shown in the code snippet), it would represent the actual file content suitable for saving or passing to other nodes.

Dependencies

• Requires an API key credential for authenticating with the ZapSign API.
• Uses environment variables to determine the API base URL:
  • ZAPSIGN_API_BASE_URL_SANDBOX (for sandbox environment)
  • ZAPSIGN_API_BASE_URL (for production environment)
• Relies on the ZapSign REST API endpoints for document operations.

Troubleshooting

Common Issues

• Invalid or missing Document Token: The operation requires a valid document token; ensure it is correctly provided.
• Network or API errors: Connectivity issues or incorrect API credentials may cause failures.
• Document not found or access denied: The token might be invalid, expired, or the authenticated user lacks permission.

Error Messages

• If the document token is missing or empty, the node will throw an error indicating the requirement.
• API errors from ZapSign (e.g., 400 Bad Request, 404 Not Found) are propagated with descriptive messages.
• Errors during file download (if applicable) will indicate failure to retrieve the document content.

Resolution Tips

• Verify the document token is correct and corresponds to an existing document.
• Check that the API key credential is valid and has necessary permissions.
• Confirm network connectivity and that the ZapSign API endpoint is reachable.
• Review any error messages for specific causes and adjust parameters accordingly.
