E-Signature

Send any Anvil-generated document (Quote, PI, CI, contract) for legally-binding e-signature via DocuSign, HelloSign, 法大大 (Fadada), or e-签宝 (E-qianbao). The signed PDF flows back into the document timeline automatically.

What It Does

  • One-click "Send for signature" from any document.
  • Tracks status (`SENT`, `VIEWED`, `SIGNED`, `DECLINED`, `EXPIRED`).
  • Accepts provider webhook callbacks and updates the document automatically.
  • Multi-signer support with ordered or parallel signing.

    • When to Use

    Whenever a document needs a signature — sales contracts, NDAs, distributor agreements, large quotes that act as commitments.

    Sending for Signature

    curl -X POST https://api.anvilhk.com/api/v1/esign/send \

    Gotchas

  • Each provider has its own pricing on top of Anvil's. DocuSign envelopes are billed by DocuSign once you exceed your plan's bundled allotment.
  • For China mainland, Fadada / E-qianbao are the only providers recognised by Chinese courts. Don't use DocuSign for a domestic Chinese contract you might enforce in court.
  • The signed PDF is fetched and stored in Anvil's S3. Even if you delete the envelope at the provider, Anvil keeps the audit copy unless you explicitly purge.
