The requiresAck field is an optional boolean sent in the initial /purchaserequests API call that defaults to false. If requiresAck is set to true, the customer will not be notified of the completed transaction until the purchase request has been explicitly acknowledged by a successful call to the /ack endpoint. This allows merchants to control the timing of customer notifications, ensuring that internal systems have processed the transaction before the customer is alerted.

This endpoint does not require any request body or payload.

A successful call to this endpoint will return a 204 No Content status, indicating that the acknowledgment was received and processed successfully.
