Feature Request: Add inventoryPolicy to ProductVariant in Storefront GraphQL API

Hydrogen and Storefront APIs
1

The Storefront API currently exposes these inventory-related fields on ProductVariant:

  • availableForSale
  • currentlyNotInStock
  • quantityAvailable

However, it’s missing inventoryPolicy, which is available in the Admin API. This field determines whether a variant allows “Continue selling when out of stock” (CONTINUE) or stops at zero inventory (DENY).

Why this is needed:

Without inventoryPolicy, there’s no way to properly fetch available variant quantities on the storefront.

For example, if a variant has quantityAvailable = 3 and a customer tries to add 5 units:

  • If inventoryPolicy = DENY, this should be prevented or at least warned
  • If inventoryPolicy = CONTINUE, this should be allowed

Currently, there is no way to distinguish between these cases. We can see the quantity available, but not whether the variant allows overselling.

Request:

Could you please expose inventoryPolicy on ProductVariant ? Alternatively, exposing a specific boolean flag like continueSellingWhenOutOfStock would achieve the same goal.
