How to detect reimbursement of in App purchase of consumable app

If I save the refund information, inquire to validation server periodically, and if there is a value inside cancellation_date of response, can I consider it reimbursed? If this method is correct, how often can I send the request to validation server?

If you know of other methods, please tell me.
