How can I find out about a payment and check this payment from Android in-app on my server?

Question

PHP

There is an online application for Android and there is a server for it. It is necessary to implement the purchase of game currency through the in-app, so that the server is notified about the payment received, then this payment is checked and credited to the user. In the application I use In-app Billing Version 3. I can't find anything on this issue in the official documentation. How to implement it?
