Revert Proxy API

openapi: 3.0.3
info:
  title: Revert Unified Chat Proxy API
  description: 'Revert is an open-source unified API for building product integrations. A single set of REST endpoints normalizes third-party CRMs, chat/messaging, ticketing, accounting, and ATS providers into unified data models, while Revert manages OAuth connections, token refresh, retries, and a passthrough proxy for provider-native calls.


    Authentication uses an `x-revert-api-token` header (your Revert API key) plus an `x-revert-t-id` tenant header identifying the linked customer connection, and an optional `x-api-version` header.


    STATUS - The hosted Revert Cloud service (https://api.revert.dev) has been retired; Revert has joined Ampersand and revert.dev no longer resolves as of 2026-07-12. This specification is preserved from the open-source, self-hostable backend (github.com/revertinc/revert). Paths, methods, headers, and unified fields were read from the repository''s Fern API definition (fern/definition/) and Express route registration; response payload schemas are modeled from the unified type definitions and are simplified where noted.'
