Signeasy Webhooks API

openapi: 3.1.0
info:
  title: Signeasy API
  version: '3.0'
  description: >-
    RESTful eSignature API (v3) for the Signeasy contract and signature platform.
    Send documents for signature (envelopes), embed signing and sending inside your
    own app via iframes, manage reusable templates with merge fields, upload original
    documents, fetch the authenticated user, and receive signature lifecycle events
    via webhooks.


    Confirmed endpoints (paths and methods) were extracted from the OpenAPI
    fragments embedded in the public Signeasy API reference at docs.signeasy.com.
    A small number of endpoints (marked with x-modeled: true) are modeled from the
    guides and the envelope object documentation where the public reference does not
    embed a machine-readable definition; verify these against the developer portal.


    All requests use the base URL https://api.signeasy.com/v3 and are authenticated
    with an OAuth 2.0 Bearer access token (sandbox or live).
