The AUTHORIZATION IS NOT AFFECTED. This stops a single charge; the mandate keeps billing and future cycles are still scheduled. To end the mandate itself — which cascades over every debit scheduled under it — use POST /v1/payer/authorizations/{authorization_id}/cancel instead. The two are told apart on the wire by the camt.055 reason: SLBD here, CCLD there. THE WINDOW CLOSES AT MIDNIGHT of the settlement date, in America/Sao_Paulo: the payer may cancel up to 23:59:59 of the day before, and a request at or after 00:00 is refused with PIX-0825. That boundary is where the 00:00-08:00 settlement window opens, so a cancellation admitted past it would race the debit it is trying to stop. A DEBIT ARISING FROM A POST-DUE RETRY (purpose NTAG) CANNOT BE CANCELLED HERE, at any hour, and is refused with PIX-0826 (Guia v1.2 §5.1): the retry is a collection the payer already authorized, and ending the mandate is the payer's remedy. The receiving side may still cancel that same charge. The cancellation is communicated to the receiving PSP by camt.055, raised asynchronously from an obligation written in the same transaction as the cancellation. The payer is notified of the cancellation unconditionally, including when scheduling notifications are disabled. ## OpenAPI ````yaml /pt/openapi/v3-current/pix-lerian-pixauto.yaml post /payer/scheduled-payments/{scheduled_payment_id}/cancel openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: >- Pix Automático payer-facing API — deciding an authorization request raised by the receiving end, managing the payer-configurable parameters of a granted mandate, and revoking it (Guia de Implementação do Pix Automático v1.2 §3 and §6). ## Trust boundary This API is **machine-to-machine**. The caller is the client PSP's backend, authenticated with an application token; the token names that application and never one of its customers. The account therefore has to arrive in the request, and it does so in one of two shapes: ten routes take it in the **`X-Account-Id`** header, the same header SPI, DICT and COB use for the same job, and `POST /v1/payer/authorization-requests/from-qr` takes `payerAccountId` in the body — that route creates a pending request for a mandate that does not exist yet, so the account is part of what is being created rather than a scope on an existing resource, and a header beside the body field would be a second source for one value. Either way the value is the caller's **declaration** of which of its own customers it is acting for. **It is not proof that the end user controls that account, and this API cannot make it one.** Authenticating the payer and authorising its own customers against one another is the calling PSP's responsibility. What this end enforces is consistency: an absent header is 400 (PIX-0001) and a malformed account is 400 (PIX-0017 on the header, PIX-0003 in the body), and a resource that exists under a different account than the one named is **404**, not 403: the account is a predicate on the lookup, so this end never learns the resource exists elsewhere and cannot confirm it. Within one lookup, absence and a resource outside the selection get the same answer. license: name: Lerian Studio General License title: Pix Lerian — Pix Automático version: 1.0.0 servers: - url: https://api.example.com/pixauto/v1 description: >- Replace the example host with the URL provided during environment onboarding. security: - BearerAuth: [] tags: - description: >- Authorization requests raised by the receiving end and answered by the payer.

Replaying the same key with a divergent method, URL or body is PIX-0031 @ 412. X-Account-Id is part of the compared request too, so replaying one account's key under another account is divergent rather than a replay. example: payer-decision-20260827-001 in: header name: X-Idempotency required: true schema: maxLength: 64 minLength: 1 type: string - description: >- Internal identifier of the scheduled debit being cancelled.

The same X-Idempotency header was replayed with an identical request, so the FIRST call's response body is returned verbatim and nothing was reprocessed. A replay answers 200 whatever the original status was, so a client tells a replay from a fresh execution by the status code alone. NOTE: this 200 depends on the replay cache. The gate DEGRADES when the cache is unavailable -- it still demands the header, and each route still refuses a second effect through its own durable guard -- but a repeat is then answered by that guard rather than replayed, which for most routes is 409. A client must therefore treat 409 as a possible answer to a retry it believes is a replay, and must not read it as proof that a competing change happened.
