  title: Formance Platform Auth Orchestration API
  description: Open-source financial infrastructure for money movement. This specification describes the REST surface of the Formance Platform across its modules - Ledger (v2), Payments, Orchestration / Flows (v2), Wallets, Reconciliation, Auth, Webhooks, and Search - as exposed by Formance Cloud. All resource modules are served under a per-module path prefix (for example `/api/ledger`, `/api/payments`) on a single stack host and are secured with OAuth2 client-credentials Bearer tokens issued by the Auth module.
