They ordered a payment gateway to integrate online courses and memberships (paying content access) with the payment system CloudPayments. The task is quite complicated, as it was necessary to set up the automatic payment log from the cursus listener card, as well as the subscription and cancellation mechanisms of regular payments. Nikolai developed the payment gate plugin and to set up integration.
The project was difficult, but Nikolai worked well. We are planning to work with him in the future.
