You can split a Shopify fulfillment order by defining split groups containing specific line_item_ids and quantities. This separates a multi-line order into independent fulfillment orders so each group can ship separately with its own tracking.

Yes, you can preview a fulfillment order split by running the operation with dry_run enabled. This shows the intended split outcome and validates line item quantities safely before executing the irreversible fulfillmentOrderSplit mutation.

Splitting a Shopify fulfillment order requires an OPEN fulfillment order status and GraphQL read_fulfillmentOrders validation. Line item IDs must exist in the target order, and requested quantities cannot exceed the remaining unfulfilled quantities.

Shipment splitting fails when line_item_ids do not exist in the target fulfillment order or when requested quantities exceed remaining quantities. Validating inputs with a dry run first ensures the fulfillmentOrderSplit mutation executes successfully.

You need to split fulfillment orders when items in a single order must ship from different locations, require different carriers, or have different shipping dates. This allows each warehouse or carrier group to process and track shipments independently.
