# New Create Fulfillment Request Validation

As of Admin version 2024-04 , there cannot be multiple of the same `fulfillment_order_id` within the `line_items_by_fulfillment_order` param for the REST "Creates a fulfillment for one or many fulfillment orders" [API](https://shopify.dev/docs/api/admin-rest/2024-01/resources/fulfillment#post-fulfillments) and GraphQL `fulfillmentCreateV2` [mutation](https://shopify.dev/docs/api/admin-graphql/2024-04/mutations/fulfillmentCreateV2).

Please combine any payload with the same `fulfillment_order_id` into one group.
