The function will only run within the context of those specific delivery methods. As of Admin GraphQL API version `2024-10` and `unstable`, you can * Use the [FulfillmentConstraintRuleCreate](https://shopify.dev/docs/api/admin-graphql/unstable/mutations/fulfillmentConstraintRuleCreate) mutation to register your new Fulfillment Constraint function and associate it with one or multiple delivery methods. A new required input field `delivery_method_types` will be added. * Use the [FulfillmentConstraintRuleUpdate](https://shopify.dev/docs/api/admin-graphql/unstable/mutations/fulfillmentConstraintRuleUpdate) mutation to update delivery method(s) for an existing registered function. Existing fulfillment constraint functions will continue to run for `SHIPPING`, `LOCAL` and `PICKUP_POINT`.
