I am having the worse time trying to figure out this thing, i’ve read and watched every documentation and video i could possibly find and turns out, there is not a single tutorial or documentation out there that is complete that takes you from start to finish when it comes to In App Purchases, so once again i am at the mercy of your responses, before i delete the damned Android project and go back to PC 
According to Epic’s documentation on IAP we get this :
PlayFab gives you this:
Do i need both? Do i skip the UE’s node and go straight to the PlayFab plugin’s nodes to retrieve my product?
Also on the first image the String variable “IAP from Game Instance”… what the hell is happening in the game instance that populates this variable? Where and how is that content coming from? Straight from Google Play Console? From PlayFab? from Xsolla? Some other magical plugin i am unaware off?
Moving on.
Again from Epic’s official documentation
After feeding the Item identifier into the Make an in app purchase node what happens?
I thought that at this point that magical window that prompts the user to enter his payment info would appear, but that won’t happen if you follow the documentation to the letter, there are missing steps to get to that window, a lot of them. What are they?
Same thing, but PlayFab node
As before? One or the other? or both nodes are needd?
Using just PlayFab only for virtual Currency in this setup, it works if i have given some Virtual Currency to the player from the back end.
Here’s where it gets tricky, PlayFab offers an Add On for Google Play Payments, in order to use this Add On you need to provide it with: Google App Package ID and License Key.
To get those i need to upload my .APK file to Google Play Store, if i compile my project and upload it as it is to test the In app Purchases would fail miserably because the Code won’t be there, and i cannot get the Code i need there unless i upload it to the store. Infinite loop detected, my brain broke. So clearly i am missing something, or rather, quite a few things apparently.
So i am humbly begging an Angel from this community that can actually help, please for the love of god and whatever you hold dear, spare me a few minutes of your time and explain in layman terms what i need to do to sell a virtual item to a player via In App Purchases.
I am more than willing to pay any of you for a private tutoring session regarding this, and afterwards ill create a tutorial with everything you showed me a revere you as a God.
Thank you, and hopefully i won’t be committed to an insane asylum by the time this post gets some replies.
