Pay-by-Link

Overview

The service allows you to get a payment link, to be sent via email or chat to the customer in order to perform a transaction. By clicking on the link, the customer is redirected to the gateway checkout page, from where he can choose to pay by payment card or alternative methods.

The generated link is unique per transaction, you will not be able to send the same link to multiple customers.

This section presents Pay-By-Link link generation via API, but you can also use it via XPay back office.
