Payment Customization Function activation without app UI or hosting (extension-only app)

[abrar_anwar]

Hi everyone,

I’ve built a extension only app that rearrange payment method based on cart attribute. so it works well using shopify app dev but when i deploy that app the customization block does show in the payment customization but I can’t enable it because the functions instance is not created yet.

I tried to run the mutation using Shopify Graphiql app but it does not work either and throughs this error

“Function payment-customization not found. Ensure that it is released in the current app (2315872), and that the app is installed.”

I see other dev post they said they activated it using graphiQL app but i don’t find any option to run a mutation in the context of other app in graphiQL just like shopify CLI while running shopify app dev command.

Thanks in advance — any clarification from Shopify or other devs would help a lot.

I already shared this in the thread you posted in.

deliveryCustomizationCreate - function not found

Just wanted to provide an update that we are looking into a better path forward for extension-only apps to activate Functions, but are not able to provide any information at the moment. In the meantime, we recommend: using the GraphiQL app through collaborator access to run the GraphQL mutation using functionId instead of functionHandle in the GraphQL mutation
