Hello Baron.
I set everything up as in the video. But I still get message with "Billing is not available" when I try to buy item with "0" ID, that is registered in SteamWorks.

@newlife

Hey newlife, which scripts, would you mind sharing so I can check which ones changed? What did you find caused issues?

And those steps he gave me for upgrading 4.3.7 in Simple IAP 1, not 2. Not sure if it's the same for Simple IAP 2.

I dont remember all the scripts, I just deleted them in order to make my project work. A couple in Scripts folder and around ten in Editor folder. Those steps are very similar to the steps described here (which I also followed) https://flobuk.com/forum/topic/1469/release-notes/42?_=1620345641287.

@newlife whoops, I forgot to disable client receipt validation by default.

In the ReceiptValidatorClient script at line 9, comment out the define:
//#define VALIDATION_CLIENT

Thanks for the notice.

I only need Pay Pal for the Web platform.

Thanks. Unfortunately for the Web platform, there is only a billing override for PlayFab PayPal (Simple IAP System > Setup tab), so you have to use category overrides with PayPal enabled indeed (or if you have different product identifiers on each platform, use product overrides instead like you did already).

In "Simple IAP System 2" I didn't find a single function with a callback that would spend on a purchase and tell me the result of a callback where I will save the purchase data, but I think there is such a function.

The callback on a successful purchase is "purchaseSucceededEvent". Please see the scripting reference, "Events" section for a full list of available callbacks. Also have a look at the IAPListener script, which subscribes to this callback for displaying purchase feedback to the user. Note that you do not have to grant currency to the user manually - you can specify the reward in the product directly. This should cover the local player inventory already.

As for updating the user's currency amount on your server, you would implement a webhook via the PayPal developer page and listen to incoming transactions from PayPal servers directly. No communication about purchases should be required by the client, to prevent hacking and fraudulent requests to your server. Adding a server-to-server connection between PayPal and your server is not something within the scope of Simple IAP System.

A quick note about the "Billing is not available" message as well: this usually means that the billing configuration is not done correctly. I guess in the custom store - PayPal section, you did enter "Sandbox Client ID", "Sandbox Secret" and "Return URL" as mentioned in the PayPal guide, but removed them in your post for privacy? These values are required to be able to connect to PayPal.

Thanks! Could you try to update/redownload the asset with the version from today?

On package import, only select the SteamStore script to not overwrite any of your other changes.
