Reverses a payment request you identify by its card-provider reference instead of its ID: the account comes from paymentRequestReference.cardProviderReference (type + referenceId) and the request from its externalId. Behavior and response — including the { "fiat": <number>, "crypto": "<string>" } amount objects — match reversing by ID. Send a unique idempotencyKey; repeating the same key and body returns the original result. Concept guide: Payment requests
