Changelog

Every change to the SignAnything API that you can see, newest first.

4 November 2026

  • Developer docs. Guides, the API reference and this changelog now live at https://api.skanything.io/v1/docs. The reference is generated from /v1/openapi.json, and you can try test-mode calls from it.
  • Error links. The type of every error is now https://api.skanything.io/v1/docs/errors#<code> (it was https://skanything.com/docs/errors#<code>, which now redirects). code is unchanged — keep branching on it.
  • Send test picks an event. POST /v1/webhooks/{id}/test takes an optional { "type": "…" } and sends a realistic sample of that event, marked "test": true.
  • Signed PDF includes the certificate. GET /v1/envelopes/{id}/signed_pdf returns the signed document with the certificate of completion as its last pages, inside the seal. GET /v1/envelopes/{id}/certificate still returns the certificate on its own.

Version 1

The first version of the API: envelopes, recipients, documents, fields and the audit trail; templates; webhooks; the account; and KeepAnything files, uploads, sharing and the change feed.
