Sproof provides a premier platform for qualified electronic signatures (QES), and this integration allows you to retrieve document metadata, monitor signature requests, and manage contacts through natural conversation.
What you can do
- Document Orchestration — List all managed documents and retrieve detailed profile metadata, including signature status programmatically.
- Signature Request Control — Create and monitor signature requests to ensure your legal documents are executed efficiently directly from the AI interface.
- Contact Management — Access and monitor your contact database to keep your signer records synchronized via natural language.
- Profile & Account Oversight — Retrieve detailed account profile metadata and monitor system usage to ensure your signature pipeline is optimized.
- Compliance Monitoring — Track document validity and signature authenticity using simple AI commands.
How it works
