# Update computer or user targets using domain and value pairs

Updates the targets of an existing collection, configuration using domain and value pairs.

**Modes:** Pass appendTargets=true to add to existing targets (APPEND). Omit this parameter to replace all targets (REPLACE). Note: REPLACE is not supported for user targets — use APPEND instead.

**Scope Validation:** Each resources(Computer or User) must be within the technician's assigned scope. To look up resource Domain and name for collection, use [ComputerDetails](https://www.manageengine.com/products/desktop-central/help/api/cloud/computers-getcomputers.html) to get all computers. This is the default format. Omit useResourceIdFormat from the request body, or set it to false explicitly.

## Header

`Authorization: Zoho-oauthtoken d92d4xxxxxxxxxxxxx15f52`

## Request Parameters

### Request Headers

- **Content-Type** (`string`, Mandatory): `application/modifyTargets.v1+json`
- **Accept** (`string`, Mandatory): `application/modifyTargets.v1+json`

### Path Parameters

- **collectionId** (`string`, Mandatory): The unique numeric identifier of the collection whose targets are to be updated. Fetch from [Get Configurations View](https://www.manageengine.com/products/desktop-central/help/api/cloud/deployment-fw-get-configurations-view.html).

### Request Body

`application/json`

- JSON Object
  - **useResourceIdFormat** (`boolean`, Optional): Mandatory. Must be false (or omitted) to activate the legacy name/domain path. When true, use `targetDetails` (Resource ID path) instead.
  - **appendTargets** (`boolean`, Optional): Optional. When true, new targets are appended to the existing target list; duplicates are silently skipped. When false (default), existing targets are fully replaced.
  - **targets** (`JSON Array`, Optional): Mandatory when useResourceIdFormat=false. Array containing a single filter entry with name/domain pairs. Must NOT be combined with `targetDetails`. Minimum 1 item; minimum 1 value inside filter.values.

## Response Parameters

### HTTP Code 200

Response Body — `application/json`

- JSON Object
  - **collectionId** (`long`): The collection ID whose targets were updated. Fetch from [Get Configurations View](https://www.manageengine.com/products/desktop-central/help/api/cloud/deployment-fw-get-configurations-view.html).
