Developers can now choose their own app store categories
Shopify App Store
Effective November 01, 2022
Starting November 1, 2022, you can self-categorize your app once using the app submission form in the Partner Dashboard. Categories can be chosen by selecting up to two tags from our updated app categories that best describe the main function of your app. You can later appeal to change your app’s categorization if its capabilities change.
