All properly functioning fulfillment services now have the `fulfillmentOrdersOptIn` field set to `true`. In the `2024-04` API version, the `fulfillmentOrdersOptIn` field becomes nullable and defaults to `true` in the [fulfillmentServiceCreate](https://shopify.dev/docs/api/admin-graphql/2024-04/mutations/fulfillmentServiceCreate) mutation and the [Create Fulfillment Service](https://shopify.dev/docs/api/admin-rest/2024-04/resources/fulfillmentservice#post-fulfillment-services) REST endpoint. This field will be removed from the mutation input and the REST endpoint parameters in the subsequent API version (`2024-07`). To prepare for the `2024-07` API version release, stop supplying the `fulfillmentOrdersOptIn` parameter when creating a new fulfillment service.
