# Introduce Fulfillment Constraints built on Shopify Function

* As of `2023-10` version of the Shopify Functions API, you can use the Fulfillment Constraints API to have a higher degree of customization when defining fulfillment and delivery strategies. With this API, checkout won’t return any shipping rates if the configured constraints can’t be met.
* For example, you can specify that certain products must be fulfilled from a specific location, based on buyer information, cart information or metafields.
* Learn more about Fulfillment Constraints on [Shopify.dev](https://shopify.dev/docs/api/functions/reference/fulfillment-constraints).
