Module: 7. Monetization

Lesson 4. Selling Virtual Values: Realizing Interaction

The main thing in the lesson

• •
  In the mini-app settings in the section Payments you need to specify the address of the server part for notifications, and among the testers - one of the administrators. Testers buy products and subscriptions without spending real votes. Test notifications have a suffix _test in the title.
• •
  All notifications are sent as POST requests to the specified address. Before processing them, check the signature of the request.
• •
  If something goes wrong in the process of processing the payment notification, you need to return the error so that the server part of the VKontakte knows how to proceed.
