AUTH_TOKEN_VERIFICATION_FAILURE (Amazon Appstore DevTest for IAP)

[Emma]

Hi,

DevTest for IAP supports apps using Appstore SDK version 3.0.3 and higher, and Fire TV devices running Fire OS 6 or later. Currently, DevTest is not supported on Fire tablets, which may be the cause of the issue.

Thank you so much.

I’m sorry for overlooking that DevTest for IAP only supports Fire TV devices.

Hi @Super_Mario

Just on the off chance, might be worth taking a look at the following post:

Error on startup for IAP Billing Client

Thank you @Levon for your assistance. I now have it working! (recording here in case anyone else hits this issue) Going through all the documentation the solution I found was not obvious. (well not to me) The key to get it working for me was to update the proguard-rules.pro file to include: -dontobfuscate in addition to the data specified here: It is mentioned in the next section in that document - but not as a required change.

It was the obfuscation that caught me out.

I did it. I did everything but issue is still here. Even on FireTV devices.

Currently, DevTest is not supported on Fire tablets, which may be the cause of the issue.

Could you show us where exactly in documentation is written this. Additionally, DevTest for IAP crashes with the same AUTH_TOKEN_VERIFICATION_FAILURE on Fire TV devices running Fire OS 7.
