We are developing a shopify app. From our website, user can connect to their shopify store.
How to test dev app with proper oauth flow. When trying with public app it requires us to submit for review. For custom apps standard /admin/oauth/authorize does not work. We would like to test the flow from our website side.
If a store has custom domain should we need to form the oauth connect url using the custom domain or the root domain i.e. myshopify.com
Can API request be made using custom domain or we need to use myshopify.com domain?
