The recovery changes to REFUNDING, and the updated recovery is returned with HTTP 200. Returns 404 when no active recovery with that ID belongs to the participant and 409 when its current state does not allow a refund. The response is a concise funds recovery representation. ## OpenAPI ````yaml en/openapi/v3-current/pix-lerian-dict.yaml POST /dict/funds-recoveries/{id}/refund 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/funds-recoveries/{id}/refund: post: tags: - Funds Recoveries summary: Initiate a refund for a funds recovery description: >- Initiates a refund for a funds recovery in the ANALYSED state, within the scope of the participant determined by the authenticated tenant.
