Hey @RRN!

Yes yes, RevenueCat does support SKPaymentTransactionObserver so this flow to promote IAPs will work for you  

Thanks!

Hi, thanks for your answer. Do you have a guide to set it up?

@RRN Nope because there is nothing you should have to do! The SDK is already observing it and will handle purchases that come in through that method/flow automatically  

I am rather new here, so I just set it up on the “App Store Connect”, then everything will work fine?

@RRN Ideally! The RevenueCat SDK listens for something to come through in that observer and then it should automatically open up the IAP purchase modal for that  

If you get issues and it doesn’t work just come back to us and we’ll help you out!

Hi, I just tested, it can open the app, but the IAP purchase modal doesn’t open automatically. 

@RRN Ah! Hmmm… thanks for letting me know! I’ll give a try myself and see what I can come up with. What version of the SDK are you using?

I am not sure, how can I check?  It should be pretty old, at least 1 year ago. 

@RRN 

• If you are using CocoaPods, you can check in your Podfile.lock or Podfile
• If you are using SPM, you can check the “Package Dependencies” (see image below) in the Project navigator

• If you are using Carthage, you should be able to check in your Cartfile.lcok

Thanks, it is 3.2.2  :)

@RRN 

Okay, I was mistaken! You do need to do _a little_ bit of work

You need to implement on of the `PurchasesDelegate` functions - https://docs.revenuecat.com/docs/configuring-sdk#ios

extension AppDelegate: PurchasesDelegate {
    func purchases(_ purchases: Purchases, shouldPurchasePromoProduct product: StoreProduct, defermentBlock makeDeferredPurchase: @escaping DeferredPromotionalPurchaseBlock) {

        makeDeferredPurchase { (transaction, customerInfo, error, success) in
            print("Yay")
        }
    }
}

It would look something like this You need to call `makeDeferredPurchase` when your app is in a state where I can make the purchase  

Note: These docs and example code are using our new v4 SDK. Which would be good to upgrade to at some point but it could require a little bit of migration.

The v3.2.2 docs can be found here - https://docs.revenuecat.com/v3.1/docs/configuring-sdk#ios

Hopefully this helps but let me know if this still doesn’t work!

extension AppDelegate: PurchasesDelegate {
    func purchases(_ purchases: Purchases, shouldPurchasePromoProduct product: StoreProduct, defermentBlock makeDeferredPurchase: @escaping DeferredPromotionalPurchaseBlock) {

        makeDeferredPurchase { (transaction, customerInfo, error, success) in
            print("Yay")
        }
    }
}

Thanks, I will test it!!
