## Mutations with this payload

* [inventory​Transfer​Set​Items](https://shopify.dev/docs/api/admin-graphql/latest/mutations/inventoryTransferSetItems)

  mutation

  This mutation sets the quantity for one or more line items on a Transfer.

  Only the items you include in the `lineItems` field are updated. Items already on the transfer but not referenced in your update will stay unchanged. Each inventory item may appear at most once in `lineItems`; duplicate `inventoryItemId` entries are rejected.

  For each entry in `lineItems`:

  * If the inventory item isn't yet on the transfer, a new line item is added with the provided quantity.
  * If the inventory item is already on the transfer, the provided quantity replaces the line item's [`processableQuantity`](https://shopify.dev/docs/api/admin-graphql/latest/objects/InventoryTransferLineItem#field-InventoryTransferLineItem.fields.processableQuantity). Any quantity outside the processable portion (for example, already shipped or picked for shipment) is preserved, so the resulting total quantity equals the preserved portion plus the provided quantity.

  Passing a quantity of `0` is only allowed for transfers in `DRAFT` status; on `READY_TO_SHIP` or `IN_PROGRESS` transfers it returns an `INVALID_QUANTITY` error. On `DRAFT` transfers, `quantity: 0` leaves a zero-quantity line item on the transfer; it does not remove the item. To remove a line item from a transfer, use [`inventoryTransferRemoveItems`](https://shopify.dev/docs/api/admin-graphql/latest/mutations/inventoryTransferRemoveItems).
