How to validate in-app Google Play transaction?

I found this section

https://api.backendless.com/7DDF8A37-3FEA-7574-FFFD-F85AA25C6C00/70EBDF10-0B9F-F91F-FF59-908EB9543700/files/for_questions/backendlessQuestion1.png</img>
but I cant find any documentaion about it. How should I validate transactions from my app?

Hello Timur,

please check this doc.
We’ll update the documentation for v4 as soon as possible.

Dear Olha,

I cannot find any document by provided you link.
Where I can read about in-app purchase validation in backendless?

Thank you in advance.
