I am developing an app with checkout UI extensibility, where I am calling a graphQL API to fetch the the product and it variants. I need the field “quantityAvailable” for the variant. Here I am sharing the query: query { product(id: "${lineProductID}") { id title …

Did you find a solution to this?

@Sanchari I got the same exact error trying to access “quantityAvailable”: it complains about missing “unauthenticated_read_product_inventory” access, yet I can see it there in the apps’ scopes. Did you figure out the solution? Thanks.

Hey! I solved this. You have to check this field in your headless plugin settings.

Access denied for quantityAvailable field. Required access:unauthenticated_read_product_inventory
