tutorials about the new built-in IAP system

any tutorials about IAP implementation in the newest Unity 5.3 ??
I read the docs and tried but noway

I made a new class file including the codes here
http://docs.unity3d.com/Manual/UnityIAPInitialization.html

this event should be called , when the user buy a stuff

Code (CSharp):

1.  public PurchaseProcessingResult ProcessPurchase (PurchaseEventArgs e)
2.     {
3.         return PurchaseProcessingResult.Complete;
4.     }

the question :- what the codes should I write/function that I should call
when the user hit "buy" button ??

 

We will be rolling out more and more detailed information on our services. It was @Matthew Schell that did that one, and he may know more.

What I'd suggest would be posting your specific question in the services section and try to get an answer there. You can tag me on the post or post the URL here, and I'll go take a look when it's up.

 

I`m testing my store with information founded in this link:

Also, you may need to add to your configuration builder your key:

Code (CSharp):

1.  
2. builder.Configure<IGooglePlayConfiguration>().SetPublicKey("yourRSAkey");
3.  
4.
