I am creating app extensions. In theme extension, I was able to get if my theme extension was enabled or not using graphql and accessing theme code. How do I do it for checkout UI extension?
It’s not possible yet.
There’s no GraphQL query for reading the current extensions/sections active on Checkout or Customer Account pages yet.
There is a webhook available to subscribe to for when merchants transition to Customer Accounts, but the final piece is querying their current Checkout/Customer Account pages to verify your app’s block has been added.
