# Creates several warehouses in one call.

`POST /inventory/warehouses/bulk`

Group: Inventory › Warehouses · Operation ID: `bulkCreateWarehouses`

All or nothing. Every entry is checked before any is written, so one rejected entry leaves the store untouched and the whole call fails. The response is the created warehouses in the same order as the input. Use POST inventory/warehouses to create a single warehouse.

## 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`: bulkCreateWarehousesInput.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `warehouses` | array of object | yes | The warehouses to create. If any entry is invalid, nothing is created and the whole call fails. |
| `warehouses[].locationCode` | string | yes | The location code of the warehouse, for example 'WH-01'. Required. It must be unique within the tenant and within this request. |
| `warehouses[].name` | string | yes | The site name of the warehouse, for example 'Rotterdam Distribution Center'. Required. |
| `warehouses[].entityId` | string | yes | The unique identifier for the legal entity that owns this warehouse. Required. An unknown identifier fails the whole call with ENTITY_NOT_FOUND, which names this entry's index. See id on GET base/entities. |
| `warehouses[].inventoryLocationType` | string, one of `"WAREHOUSE"`, `"STORE"`, `"VIRTUAL_QC"`, `"VIRTUAL_RECEIVING"`, `"VIRTUAL_SHIPPING"`, `"EXTERNAL_3PL"`, `"EXTERNAL_CONSIGNMENT"` | yes | The kind of location. Required. |
| `warehouses[].isActive` | boolean | no | Whether the warehouse can be selected on new inventory documents. Defaults to true. |
| `warehouses[].isPrimaryReceiving` | boolean | no | Whether this is the entity's primary receiving warehouse. Defaults to false. At most one warehouse per entity is meant to be the primary receiving warehouse. It is not enforced, and a request setting it on several is accepted. |
| `warehouses[].warehouseTypeId` | string | no | The unique identifier for the warehouse type, which limits the document types the warehouse allows. Omit to allow every document type. There is no endpoint for it. |
| `warehouses[].addressLine1` | string | no | The first address line: street number and name, or PO box. |
| `warehouses[].addressLine2` | string | no | The second address line: apartment, suite, unit, building or floor. |
| `warehouses[].city` | string | no | The city or locality. |
| `warehouses[].stateProvince` | string | no | The state, province or region. |
| `warehouses[].postalCode` | string | no | The postal or ZIP code. |
| `warehouses[].countryCode` | string | no | The country of the address. Format ISO 3166-1 alpha-2, for example 'NL'. It is not validated against the ISO list. |
| `warehouses[].region` | string | no | A free-text business region grouping, independent of country and state. |

```json

  "warehouses": [
    {
