Purchase value way too high

I have some weird purchases in my game and I don't know how that was even possible. Is this legit (hardly since there's no 999$ pack)? Can it be cheated? Either way it completely ruins the KPIs.


Test payments are fine, so the player must have done something special (or it's a bug in the backend).
The 99999 is the placeholder price of the bundle.


One thing I noticed is that it says Client instead of Catalog (which test and verified real payments do), right under the RM price.

I since then removed the RM price from the bundle you receive from the ValidateGooglePlayPurchase call, in hopes it's just a bug there. At least the bug/cheat hasn't occurred since then so far.

I also replaced the shop RM prices with the Dollar prices, even if the client overwrites them anyway (but those placeholder shop prices didn't show up anyway since they were a few orders of magnitude lower).

Question remains: How can someone spend $999, why does it show as a client action and how can I prevent it?

In the ValidateGooglePlayPurchase call, the PurchasePrice isn't required. If you don't pass one in, we use the RM value you have in your catalog as the price for the item. The problem is that the actual purchase price isn't in the receipt. And since the price the player pays could vary based on sale pricing, the best way to get it tracked is to get it from the client.

Ah, ok. I thought you do receipt validation for the revenue KPIs.

That leaves the question why passing a PurchasePrice sometimes doesn't work (I always send at least 0.01 as a value).
