Introduction

Envelope Signing (eSign) provides a complete set of electronic signing APIs, supporting the full workflow from file upload to signing completion.

What is an Envelope?

In Tencent eSign, an Envelope is the core container for a signing workflow. An envelope contains:

Documents — Files to be signed (PDF, Word, etc.)
Recipients — Signers or Carbon Copy recipients
Tabs — Signing fields such as signature, date, text box, etc., positioned on documents
Signing Settings — Parallel/sequential signing, whether decline is allowed, etc.

draft → sent → completed
              ↘ declined
              ↘ voided
