Hello,
The app Callback URL is used both when installing apps from App Store (when we have to redirect to Shopify), and when loading an already installed app from Admin.
How do you differentiate between the two different cases, besides doing an internal call to see if we know the app is already installed in this shop? (this useless call has to be made for every app load, instead of continuing with proper action, which would be faster for users too)
Should Shopify add "install" and "embed" parameters for these cases?
Thanks
