Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Failed In-App Purchase on IOS

Hi everyone,

Version: 4.18
Project: New and Only BluePrint (No Code)
OS: Windows 10 (upgraded from Windows 7)

I've been googling and trying to figure out why my in app purchase kept on failing and how to fix it but I still don't know how.

Right now I've created a new test project to see if it would work. The test project is packaging and installing fine, but when I went to test it on my iPhone the iap it would fail saying 'Unknown Error'. (I've setup a pop-up error widget like Unreal's Match3 so I could get a bit more info when and if it would fail.)

To go in more depth of the error I hooked my iPhone to my MacBook and opened up Xcode's Devices and Simulators window and here is what I found in my device console:

UInAppPurchaseCallbackProxy::Trigger - In-App Purchases are not supported by Online Subsystem Nov 20 12:58:10 B UE4Game[292] : [2017.11.20-17.58.10:481] [448]LogBlueprintUserMessages: [Purchase_InApp_C_0] ----PURCHASED FAILED----

This is the only thing that I could see that is causing my test project to fail. Is there anything I could do to fix it?

Let me know if more information is needed.

Thank you for your time.

Product Version: UE 4.18

Did you ever find a solution for this?

Sadly no. As I couldn't find the solution I went with a donate option that was a whole lot easier.

And we made our app paid :/

Yeah, I thought about having the app paid or not for awhile. With not finding a solution (and factors) I decided to make the app free and anyone who finds the app useful they are able to donate what they would like.

I solved it man! After 2 years, I am able to use IAPs in my game in iOS! Yeyyy.

Just use these:

That's awesome! :D Thank you, I'll have to go back to one of my earlier builds just to try it out when I have some time.
