The request has no body. Cancelling an already-CANCELLED marker is idempotent and returns 200 without changes. Returns 404 for an unknown resource ID, 403 when the participant is not authorized to cancel the marker, and 409 for another state conflict. ## OpenAPI ````yaml en/openapi/v3-current/pix-lerian-dict.yaml POST /dict/fraud-markers/{fraud_marker_id}/cancel openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: >- Public API for Pix keys, claims, fraud markers, infraction reports, and MED funds recovery. license: name: Elastic License 2.0 url: https://www.elastic.co/licensing/elastic-license title: Pix Lerian — DICT version: release-candidate servers: - url: https://api.example.com/dict-hub/v1 description: >- Replace the example host with the URL provided during environment onboarding. security: - BearerAuth: [] tags: - description: Register, retrieve, list, update, and remove Pix keys. name: Entries - description: Look up Pix keys and check whether keys exist in the DICT directory. name: Keys - description: Manage ownership and portability claims for Pix keys. name: Claims - description: Manage participant-scoped MED 2.0 funds recoveries. name: Funds Recoveries - description: Manage MED 2.0 infraction reports for the authenticated organization. name: Infraction Reports - description: Create, query, cancel, and settle MED 2.0 refunds. name: Refunds - description: Create, query, list, and cancel DICT fraud markers. name: Fraud Markers paths: /dict/fraud-markers/{fraud_marker_id}/cancel: post: tags: - Fraud Markers summary: Cancel a fraud marker description: >- Cancels a DICT fraud marker by its directory resource ID within the scope of the participant determined by the authenticated tenant.
