A new payment system has appeared in the integrations section — GoPay, a Czech payment provider that works well for sales in Czechia, Slovakia and the rest of Europe. You connect it the same way as the others: take the API access credentials from your GoPay business account and paste them into the integration settings. The article How to integrate a payment system on Kwiga explains how.
Your student pays on the GoPay page by card or another method available there and returns to your workspace — access to the product opens as soon as the payment is confirmed. Before you start selling, you can switch the integration to test mode and run a trial payment.
