Chargeback
                                    The Chargeback Webhook will send the chargeback transaction every hour.
                                    
                                    If the merchant's Webhook URL receives the request successfully, it should output {"rescode": "0000", "resmsg": "Success"}.
                                    
                                    If the Webhook URL cannot be reached successfully, or if the rescode is not "0000", the request will be re-sent up to a maximum of three times.
