OpenAPI Specification

openapi: 3.2.0
info:
  title: TRATO Contract Contracts Custom Properties API
  version: '2.0'
  description: TRATO is an AI-powered Contract Lifecycle Management (CLM) and electronic signature platform. This OpenAPI description is generated from TRATO's public developer documentation (developer.trato.io) — it faithfully represents the documented Contracts and Templates operations, their paths, methods and the JWT bearer authentication. TRATO does not publish a machine-readable spec, so request/response schemas here reflect only fields documented in the reference.
