Operation Notification: Webhook

The purchase process is carried out by the payment gateway and the resolution of the operation is returned directly in the response message. However, it is possible to configure through the PAYCOMET customer panel additional notification methods to keep users informed of the operation or launch additional mechanisms.

These notifications are identical to those submitted by other type of payment gateway products such as WEB gateway or telesales. Thus, it is possible for the customer to maintain a unified control of sales made by the business.

You can change your notifications mode on your dashboard (please, if you uses a Payment Module, please fill that info with the data given at the tutorial).

For proper notification of the payment process, it is possible to configure the notification system to provide information on the status of the operation performed by the gateway, either via e-mail, request to URL in the background (independent of the response process to the service) or both, and in general by SMS.


The information contained in a standard notification e-mail is as follows:
