Direct Payment

Overview.

The provided API documentation details the payInvoice endpoint within the Paylink API framework. This specific endpoint is designed for merchants, enabling them to create invoices and accept online payments through the Paylink gateway. The integration process facilitates the collection of card information directly from customers. This information is then utilized for processing payments on your webpage.
