I utilize realtime developer notification to process the purchases within my app. For subscriptions this works flawless, but for one time products I never received a message.


  • Subscription message
  • Test message

Not working:

  • One time product message

I use the "Test card - always approves" so the purchase came through. Even if I acknowlege it on the frontend, I do not receive any notification on the backend, but I should get one according to the docu

What is wrong here?
