We would like to integrate Odnoklassniki.ru with Playfab.
The Odnoklassniki.ru payment flow is pretty similar to Facebook:
User calls payment through UI > Odnoklassniki.ru requires a server callback to validate the purchase > If the payment is validated, Odnoklassniki.ru deducts the currency and the user can get his goods.
How can we integrate it? Is there a way for us to use PlayFab for the server callback?
