I'm facing issues with backend access, auth flow, and product filtering in my Shopify Mini.

We’re having trouble accessing our custom backend in a Shopify Mini even after adding it to trusted_domains, and we want to know how to properly test backend integrations before submission, whether the full token-based authentication flow is required for simple GET requests, and how to correctly filter products—especially for shipping attributes and category filters—since our current category queries return no results.gitu

Please create different topics for each problem/question. As for the issue with accessing custom backend, provide the exact configurations, logs, and errors you see when trying to test the integration.

This is the issue: the API works on localhost in the browser, but when we call it through the shop app, it returns an error. Furthermore we are using the window OS so it’s not even work on emulator either. We are using the command npx shop-minis dev —host=192.168.1.85

Hello!

Android runs in an emulator so by default it cannot access your server at http://localhost:5000/api/v1 - you can test this by trying to load the same url in android chrome - you will see it does not connect. You have a few options for this but port reversing might be the simplest solution - there’s some context here You can forward/reverse ports on Android device using adb - Today I Learned

Hope you can get it working!
