Apple Ask to buy questions

Hi,

I feel like I'm confused and the documentation seems to be lacking in regard to the questions I have.
iOS has the ask to buy feature, but the documentation seems vague.

I would test a lot of these questions myself, but it's hard in lockdown and I don't have access to a Mac and iOS device atm.

So the first question is what does simulateAskToBuy do? There's a post that suggests it does not work for sandbox purchases, so should I test this on the live store only?

When does OnDeferred() get called? Does it get called when the user initiated the purchase, when the user pressed "ask" or when the purchase was approved by the parent?

During process purchase the documentation suggests that for "Ask-to-buy" you need to look explicitly for the m_AppleExtensions.GetTransactionReceiptForProduct(Product) which only works on iOS/Apple TV platforms. Can you always use that on these platforms instead of purchasedProduct.receipt or only in the case of ask to buy? Is the Mac platform unsupported for ask to buy or does it send the receipt through the EventArgs like normal?

Hope someone has answers

 

simulateAskToBuy does an instant approval on the test device, it doesn't go through the parent approval process on the second (parent) device. OnDeferred lets you (the developer) know that a child has made a purchase attempt. You can put up a dialog or similar to let them know that they are waiting for approval. Finally, when the parent approves, ProcessPurchase will be called just as if the person made a normal purchase. It's my understanding that the ProcessPurchase callback can happen at any time during game play, once the parent approves. I haven't heard if Mac is supported. So in your scenario, the child would have their own Mac, as would the parent? So you know, to fully test Ask to Buy, you would need 2 iOS devices, one for the child and the other for the parent.

 

Thanks for the response that helps.

 

@JeffDUnity3D On a related question, do you know what happens on the child's end when a parent declines a purchase request? Is IStoreListener.OnPurchaseFailed called (and if so what error), or is it silently forgotten?

 

We are seeing it "silently forgotten". It can be sent "out of band" when the app may not be running. This is expected behavior

 

I tried setting the

simulateAskToBuy=true

and ran in iPhone device, it didn't call

ProcessPurchase()

after initialize buying despite you mentioned it should do an instant approval. Did I miss any step?

I'm using Unity 2018.4.23f, Unity IAP 2.2.7 from asset store and IAP 2.2.2 in package manager. Tested on iPhone 12 iOS 14.5

 

It is "supposed" to do an instant approval, we have no control over this. I've heard of other users seeing similar. Are you using a Deferred Listener? As an example, see the Sample IAP Project v2 https://forum.unity.com/threads/sample-iap-project.529555/#post-6950270

 

Yes I'm using this

_storeExtensionProvider.GetExtension<IAppleExtensions>().RegisterPurchaseDeferredListener(OnDeferred);

.

OnDeferred

was called, but

ProcessPurchase()

was not called right after that. The reason we need

ProcessPurchase()

to be called is to make sure the format or value in the apple receipt of the deferred purchase is correct and can be validated from our server.

 

We have no control over the callback timing.

 

Is it expected that

ProcessPurchase()

will be called after that (regardless of timing) or it will never be called? For my case, I waited like a couple mins but no response at all, even after restarting the app.

 

The failed event never arrives, you might have better luck on the Slow/Succeed flow. I have received it after 3-5 minutes if I recall.
