# Update a sales-tax item

`POST /quickbooks-desktop/sales-tax-items/{id}`

Updates an existing sales-tax item.

## Path parameters

- `id` string, required — The QuickBooks-assigned unique identifier of the sales-tax item to update.

## Headers

- `Conductor-End-User-Id` string, required — The ID of the End-User to receive this request.

## Request body

- object
  - `revisionNumber` string, required — The current QuickBooks-assigned revision number of the sales-tax item object you are updating, which you can get by fetching the object first. Provide the most recent `revisionNumber` to ensure you're working with the latest data; otherwise, the update will return an error.
  - `name` string — The case-insensitive unique name of this sales-tax item, unique across all sales-tax items. **NOTE**: Sales-tax items do not have a `fullName` field because they are not hierarchical objects, which is why `name` is unique for them but not for objects that have parents. Maximum length: 31 characters.
  - `barcode` object — The sales-tax item's barcode.
    - `value` string — The item's barcode value.
    - `assignEvenIfUsed` boolean — Indicates whether to assign the barcode even if it is already used.
    - `allowOverride` boolean — Indicates whether to allow the barcode to be overridden.
  - `isActive` boolean — Indicates whether this sales-tax item is active. Inactive objects are typically hidden from views and reports in QuickBooks. Defaults to `true`.
  - `classId` string — The sales-tax 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.
  - `description` string — The sales-tax item's description that will appear on sales forms that include this item.
  - `taxRate` string — The tax rate defined by this sales-tax item, represented as a decimal string. For example, "7.5" represents a 7.5% tax rate. This rate determines the amount of sales tax applied when this item is used in transactions. If a non-zero `taxRate` is specified, then the `taxVendor` field is required.
  - `taxVendorId` string — The tax agency (vendor) to whom collected sales taxes are owed for this sales-tax item. This field refers to a vendor in QuickBooks that represents the tax authority. If a non-zero `taxRate` is specified, then `taxVendor` is required.
  - `salesTaxReturnLineId` string — The specific line on the sales tax return form where the tax collected using this sales-tax item should be reported.

## Response `200`

Returns the updated sales-tax item.

- QbdSalesTaxItem
  - `id` string, required — The unique identifier assigned by QuickBooks to this sales-tax item. This ID is unique across all sales-tax items but not across different QuickBooks object types.
  - `objectType` 'qbd_sales_tax_item', required — The type of object. This value is always `"qbd_sales_tax_item"`.
  - `createdAt` string, required — The date and time when this sales-tax item was created, in ISO 8601 format (YYYY-MM-DDThh:mm:ss±hh:mm), which QuickBooks Desktop interprets in the local timezone of the end-user's computer.

  - `name` string, required — The case-insensitive unique name of this sales-tax item, unique across all sales-tax items. **NOTE**: Sales-tax items do not have a `fullName` field because they are not hierarchical objects, which is why `name` is unique for them but not for objects that have parents.
  - `barcode` string, nullable, required — The sales-tax item's barcode.
  - `isActive` boolean, required — Indicates whether this sales-tax item is active. Inactive objects are typically hidden from views and reports in QuickBooks. Defaults to `true`.
  - `class` object, nullable, required — The sales-tax 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.
    - `id` string, nullable, required — The unique identifier assigned by QuickBooks to this object. This ID is unique across all objects of the same type, but not across different QuickBooks object types.
    - `fullName` string, nullable, required — The fully-qualified unique name for this object, formed by combining the names of its parent objects with its own `name`, separated by colons. Not case-sensitive.
  - `description` string, nullable, required — The sales-tax item's description that will appear on sales forms that include this item.
  - `taxRate` string, nullable, required — The tax rate defined by this sales-tax item, represented as a decimal string. For example, "7.5" represents a 7.5% tax rate. This rate determines the amount of sales tax applied when this item is used in transactions. If a non-zero `taxRate` is specified, then the `taxVendor` field is required.
  - `taxVendor` object, nullable, required — The tax agency (vendor) to whom collected sales taxes are owed for this sales-tax item. This field refers to a vendor in QuickBooks that represents the tax authority. If a non-zero `taxRate` is specified, then `taxVendor` is required.
    - `id` string, nullable, required — The unique identifier assigned by QuickBooks to this object. This ID is unique across all objects of the same type, but not across different QuickBooks object types.

  - `customFields` QbdCustomField[], required — The custom fields for the sales-tax item object, added as user-defined data extensions, not included in the standard QuickBooks object.
    - `ownerId` string, required — The identifier of the owner of the custom field, which QuickBooks internally calls a "data extension". For public custom fields visible in the UI, such as those added by the QuickBooks user, this is always "0". For private custom fields that are only visible to the application that created them, this is a valid GUID identifying the owning application. Internally, Conductor always fetches all public custom fields (those with an `ownerId` of "0") for all objects.
    - `name` string, required — The name of the custom field, unique for the specified `ownerId`. For public custom fields, this name is visible as a label in the QuickBooks UI.
    - `type` 'amount_type' | 'date_time_type' | 'integer_type' | 'percent_type' | 'price_type' | 'quantity_type' | 'string_1024_type' | 'string_255_type', required — The data type of this custom field.
    - `value` string, required — The value of this custom field. The maximum length depends on the field's data type.
