Do we have to make first the draft app on the development account. And is that app converted to the custom app. And can I make a custom application and use it for different clients. I basically want to get products and orders from the shopify store and get that onto my platform Stockarea from where they can fulfill the orders and stuff. So how should I approach in this case?
hi @Abhira , welcome to the forums.
There are some great tutorials about setting up your first app at https://shopify.dev/tutorials
Just keep in mind, the custom 'app' won't be able to be installed on multiple stores. You could do an unlisted public app instead. See the differences here https://help.shopify.com/en/manual/apps/app-types
