  title: Estuary Flow Control Plane Auth Tenants API
  description: Representative OpenAPI description of the Estuary Flow control plane, a Supabase deployment (Postgres + PostgREST + GoTrue) that exposes the public-facing REST API for Estuary Flow. Clients authenticate with an Authorization Bearer access token, which is obtained by exchanging a long-lived refresh token through the generate_access_token RPC. Most resources are PostgREST tables and RPCs; standard PostgREST query conventions (select, filter operators like eq./gt., order, limit) apply to the table endpoints. Publishing changes to the running data plane is an asynchronous, draft-then-publish workflow. This document is a faithful representative model and is not the vendor's canonical machine-readable contract.
