Most signing tools require you to bring your own PDF. eSignature API generates the document from a template — populated with live data — and sends it for signing in the same call. One platform, one API key, one credit system.
- No separate PDF tool needed
- Dynamic data fills template fields automatically
- Signed PDF returned with audit trail via webhook
