Hello,

Im validating receipt on android and ios for subscriptions. It seems to be doing things correctly for both. Although on android one user in Turkey purchasing is causing invalid: Invalid Value http 400. How do i find out what is wrong, i only have 1.5k MAU id be surprised if someone is trying to create a fake subscription.. but who knows

I typically see the 400 errors in combination with rooted Android devices. There are some "tools" in the wild, which automatically hijack IAPs and subscribtions and create fake responses.

As long you don't have a larger amount of users affected by this, I would simply ignore it.
