Setting up deferred IAP (Unexpected Purchase/Ask to Buy)


I am wondering how to setup in app purchase for deferred status (Ask to Buy on iOS). According to the Release note of version 4.21: “OnlineSubsystemIOS purchase interface will now trigger “unexpected purchase” delegate when a deferred (ask to buy) transaction is approved”

However, I could not find any nodes that would provide the “unexpected purchase” to add to the script. I would very much appreciate any guidance on how to get the “unexpected purchase” triggered.

Couldn’t find it in blueprint neither. Guess it’s not exposed to blueprints. For c++, you can find the docs right here:
