Create Warehouse Transfer

POST /inventory/warehouse-transfers

Group: Inventory › Warehouse Transfers · Operation ID: createWarehouseTransfer

Creates a warehouse transfer as a draft. The source and target warehouses must differ.

Creates one warehouse transfer as a draft. Nothing moves until POST inventory/warehouse-transfers/:id/commit posts it. The source and target warehouses are set on the document and apply to every line. An intercompany transfer needs more: transferType 'INTERCOMPANY', a toEntityId for the receiving entity, a contractualCurrency, and a unitTransferValue on every line, all checked here rather than at commit. A batch-tracked item needs batches that add up to the line's quantity, a serialized item one serials entry per unit, and a batch or serial number new to the item is created. The whole call is one transaction, so a rejected request writes nothing. The response has the same shape as GET inventory/warehouse-transfers/:id.

Parameters

Name	In	Type	Required	Description
`Api-Version`	header	`"v1"`	yes	The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`.
`Idempotency-Key`	header	string	no	An opaque caller-chosen string (1-255 characters) that makes this request safe to retry. Repeating the same key with an identical request body replays the original response instead of re-executing - but only once that original request succeeded; a failed attempt re-executes on retry. Repeating the key with a different body is answered with 422. A key still in flight is answered with 409 - as is a key whose original request was interrupted before it finished, for a few minutes afterwards, until that attempt is presumed dead. A completed response stays replayable for 24 hours. The key is scoped to the caller, not to the action: reusing it for a different action is answered with 409 or 422 rather than treated independently. On read actions this header is ignored. On write actions that cannot offer the guarantee it is answered with `400 IDEMPOTENCY_NOT_SUPPORTED` rather than silently ignored.

Request body

Required, application/json: createWarehouseTransferInput.

Field	Type	Required	Description
`locationId`	string	yes	The warehouse the goods leave, applied to every line. See id on GET inventory/warehouses/:id.
`targetLocationId`	string	yes	The warehouse the goods go to. It must differ from locationId. See id on GET inventory/warehouses/:id.
`entityId`	string	no	The legal entity. Defaults to the entity that owns the source warehouse. See id on GET base/entities.
`documentDate`	string (date)	no	The date to give the transfer. Defaults to today. Use format YYYY-MM-DD.
`referenceNumber`	string	no	Your own reference on the transfer.
`notes`	string	no	Free text on the document.
`transferType`	string	no	The type of transfer to create. Accepted values: 'NORMAL', 'INTERCOMPANY'. Defaults to 'NORMAL'. 'INTERCOMPANY_RETURN' is created by the intercompany return flow, not here.
`toEntityId`	string	no	The legal entity receiving the goods. Required when transferType is 'INTERCOMPANY'. See id on GET base/entities.
`contractualCurrency`	string	no	The currency an intercompany transfer is contracted in. Required when transferType is 'INTERCOMPANY'. Format ISO 4217, for example 'EUR'. Each line's unitTransferValue is stated in it.
`lines`	array of object	yes	The lines of the transfer. At least one is required.
`lines[].itemId`	string	yes	The item to move. See id on GET inventory/items/:id.
`lines[].unitId`	string	no	The unit the quantity is in. Defaults to the item's stocking unit. There is no endpoint for it.
`lines[].quantity`	string (decimal)	yes	How much to move, in the line's unit. Must be greater than zero.
`lines[].notes`	string	no	Free text on the line.
`lines[].unitTransferValue`	string (decimal)	no	The contractual price of one unit, in the transfer's contractual currency. Required on an intercompany transfer. The two entities agree the price, and the API cannot derive it from a cost.
`lines[].batches`	array of object	no	The batches that make up the line's quantity. Required for a batch-tracked item, and they must add up to the line's quantity.
`lines[].batches[].batchNumberId`	string	no	The unique identifier for an existing batch number. See id on GET inventory/batch-numbers/:id.
`lines[].batches[].batchNumber`	string	no	The batch number. Naming one the item does not have yet creates it.
`lines[].batches[].quantity`	string (decimal)	yes	How much of the line this batch accounts for.
`lines[].serials`	array of object	no	The serialized units that move. Required for a serialized item, one entry per unit.
`lines[].serials[].serialNumberId`	string	no	The unique identifier for an existing serial number. See id on GET inventory/serial-numbers/:id.
`lines[].serials[].serialNumber`	string	no	The serial number. Naming one the item does not have yet creates it.
`lines[].binLocations`	array of object	no	The bins the goods leave and arrive in. Each entry names both ends of the move, and the batch or serial it belongs to where it belongs to one. Leave both names off for a quantity that moves at line level.
`lines[].binLocations[].fromBinLocationId`	string	no	The bin the goods leave, in the source warehouse. See id on GET inventory/bins/:id.
`lines[].binLocations[].toBinLocationId`	string	no	The bin the goods arrive in, in the target warehouse. See id on GET inventory/bins/:id.
`lines[].binLocations[].quantity`	string (decimal)	yes	How much moves between these two bins.
`lines[].binLocations[].batchNumber`	string	no	The batch this entry belongs to, when it belongs to one of the line's batches.
`lines[].binLocations[].serialNumber`	string	no	The serialized unit this entry belongs to, when it belongs to one of the line's serials.
