It says in the Amazon documentation for the IAP tester app:
"Before you publish your app to the Developer Portal, the app runs in sandbox mode. The IAP API detects this mode automatically. API requests are not sent to the Appstore; they are redirected locally to App Tester." Source: https://developer.amazon.com/public/apis/earn/in-app-purchasing/docs-v2/testing-iap
We now have the app published, in production, and are working on some modifications for a later version. I sometimes run the production app on the FireTV device, and sometimes the development app (same app id). I need to be sure when the IAP calls are routed via the app tester sandbox and when not. How does the "automatic detection" work? Can I control the flow somehow?
