Provide the most recent `revisionNumber` to ensure you're working with the latest data; otherwise, the update will return an error. example: '1721172183' name: type: string maxLength: 31 description: >- The case-insensitive name of this inventory assembly item. Not guaranteed to be unique because it does not include the names of its hierarchical parent objects like `fullName` does. For example, two inventory assembly items could both have the `name` "Deluxe Kit", but they could have unique `fullName` values, such as "Assemblies:Deluxe Kit" and "Inventory:Deluxe Kit". Maximum length: 31 characters. example: Deluxe Kit barcode: type: object properties: value: type: string description: The item's barcode value. example: '012345678905' assignEvenIfUsed: type: boolean description: >- Indicates whether to assign the barcode even if it is already used. example: false default: false allowOverride: type: boolean description: Indicates whether to allow the barcode to be overridden. example: false default: false additionalProperties: false description: The inventory assembly item's barcode. isActive: type: boolean description: >- Indicates whether this inventory assembly item is active. Inactive objects are typically hidden from views and reports in QuickBooks. Defaults to `true`. example: true classId: type: string description: >- The inventory assembly item's class. Classes can be used to categorize objects into meaningful segments, such as department, location, or type of work. In QuickBooks, class tracking is off by default. example: 80000001-1234567890 parentId: type: string description: >- The parent inventory assembly item one level above this one in the hierarchy. For example, if this inventory assembly item has a `fullName` of "Assemblies:Deluxe Kit", its parent has a `fullName` of "Assemblies". If this inventory assembly item is at the top level, this field will be `null`. example: 80000001-1234567890 sku: type: string description: >- The inventory assembly item's stock keeping unit (SKU), which is sometimes the manufacturer's part number. example: MPN-123456 unitOfMeasureSetId: type: string description: >- The unit-of-measure set associated with this inventory assembly item, which consists of a base unit and related units. example: 80000001-1234567890 forceUnitOfMeasureChange: type: boolean description: >- Indicates whether to allow changing the inventory assembly item's unit-of-measure set (using the `unitOfMeasureSetId` field) when the base unit of the new unit-of-measure set does not match that of the currently assigned set. Without setting this field to `true` in this scenario, the request will fail with an error; hence, this field is equivalent to accepting the warning prompt in the QuickBooks UI. NOTE: Changing the base unit requires you to update the item's quantities-on-hand and cost to reflect the new unit; otherwise, these values will be inaccurate. Alternatively, consider creating a new item with the desired unit-of-measure set and deactivating the old item. example: false salesTaxCodeId: type: string description: >- The default sales-tax code for this inventory assembly item, determining whether it is taxable or non-taxable. This can be overridden at the transaction-line level. Default codes include "Non" (non-taxable) and "Tax" (taxable), but custom codes can also be created in QuickBooks. If QuickBooks is not set up to charge sales tax (via the "Do You Charge Sales Tax?" preference), it will assign the default non-taxable code to all sales. example: 80000001-1234567890 salesDescription: type: string description: >- The description of this inventory assembly item that appears on sales forms (e.g., invoices, sales receipts) when sold to customers. example: High-quality steel bolts suitable for construction salesPrice: type: string description: >- The price at which this inventory assembly item is sold to customers, represented as a decimal string. example: '19.99' incomeAccountId: type: string description: >- The income account used to track revenue from sales of this inventory assembly item. example: 80000001-1234567890 updateExistingTransactionsIncomeAccount: type: boolean description: >- When `true`, applies the new income account (specified by the `incomeAccountId` field) to all existing transactions that use this inventory assembly item. This updates historical data and should be used with caution. The update will fail if any affected transaction falls within a closed accounting period. If this parameter is not specified, QuickBooks will prompt the user before making any changes. example: false purchaseDescription: type: string description: >- The description of this inventory assembly item that appears on purchase forms (e.g., checks, bills, item receipts) when it is ordered or bought from vendors. example: Bulk purchase of steel bolts for inventory purchaseCost: type: string description: >- The cost at which this inventory assembly item is purchased from vendors, represented as a decimal string. example: '15.75' purchaseTaxCodeId: type: string description: >- The tax code applied to purchases of this inventory assembly item. Applicable in regions where purchase taxes are used, such as Canada or the UK. example: 80000001-1234567890 cogsAccountId: type: string description: >- The Cost of Goods Sold (COGS) account for this inventory assembly item, tracking the original direct costs of producing goods sold. example: 80000001-1234567890 preferredVendorId: type: string description: >- The preferred vendor from whom this inventory assembly item is typically purchased. example: 80000001-1234567890 assetAccountId: type: string description: >- The asset account used to track the current value of this inventory assembly item in inventory. example: 80000001-1234567890 buildNotificationThreshold: type: number description: >- The inventory assembly item's minimum quantity threshold that triggers a build notification in QuickBooks. When the sum of `quantityOnHand` (current inventory) and `quantityOnOrder` (pending purchase orders) drops below this threshold, QuickBooks will notify users that more units need to be built or assembled. This helps ensure adequate inventory levels for inventory assembly items. example: 10 maximumQuantityOnHand: type: number description: >- The maximum quantity of this inventory assembly item desired in inventory. example: 200 clearItemLines: type: boolean description: >- When `true`, removes all existing item lines associated with this inventory assembly item. To modify or add individual item lines, use the field `itemLines` instead. example: false lines: type: array items: type: object properties: inventoryItemId: type: string description: >- The inventory item associated with this inventory assembly item line. example: 80000001-1234567890 quantity: type: number description: >- The quantity of the item associated with this inventory assembly item line. This field cannot be cleared. **NOTE**: Do not use this field if the associated item is a discount item. example: 5 additionalProperties: false minItems: 1 description: The inventory assembly item's lines. required: - revisionNumber additionalProperties: false responses: '200': description: Returns the updated inventory assembly item. headers: Conductor-Request-Id: schema: type: string description: The unique identifier for this API request. example: req_1234567abcdefg required: true content: application/json: schema: $ref: '#/components/schemas/qbd_inventory_assembly_item' security: - BearerAuth: [] x-codeSamples: - lang: JavaScript source: >- import Conductor from 'conductor-node'; const conductor = new Conductor({ apiKey: process.env['CONDUCTOR_SECRET_KEY'], // This is the default and can be omitted }); const inventoryAssemblyItem = await conductor.qbd.inventoryAssemblyItems.update( '80000001-1234567890', { revisionNumber: '1721172183', conductorEndUserId: 'end_usr_1234567abcdefg' }, ); console.log(inventoryAssemblyItem.id); - lang: Python source: >- import os from conductor import Conductor conductor = Conductor( api_key=os.environ.get("CONDUCTOR_SECRET_KEY"), # This is the default and can be omitted ) inventory_assembly_item = conductor.qbd.inventory_assembly_items.update( id="80000001-1234567890", revision_number="1721172183", conductor_end_user_id="end_usr_1234567abcdefg", ) print(inventory_assembly_item.id) components: schemas: qbd_inventory_assembly_item: type: object properties: id: type: string description: >- The unique identifier assigned by QuickBooks to this inventory assembly item.

For example, if an inventory assembly item is under "Assemblies" and has the `name` "Deluxe Kit", its `fullName` would be "Assemblies:Deluxe Kit". **NOTE**: Unlike `name`, `fullName` is guaranteed to be unique across all inventory assembly item objects. However, `fullName` can still be arbitrarily changed by the QuickBooks user when they modify the underlying `name` field. example: Assemblies:Deluxe Kit barcode: type: - string - 'null' description: The inventory assembly item's barcode. example: '012345678905' isActive: type: boolean description: >- Indicates whether this inventory assembly item is active.
