# Add a Telemetry Destination Workspace

`$client->beta->organization->telemetryDestinations->workspaces->add(string workspaceID, string destinationID, ?list<AnthropicBeta> betas): BetaTelemetryDestinationWorkspace`

**POST** `/v1/organizations/telemetry_destinations/{destination_id}/workspaces/{workspace_id}`

Add one workspace to a destination's workspace list.

Under `include` the workspace's spans start going to the destination. Under `exclude` they stop. A list holds at most 1,000 workspaces.

Adding a workspace that is already on the list changes nothing and returns the existing entry. An archived workspace that isn't on the list yet can't be added. A destination whose `workspaces.type` is `all` doesn't have a list, so the API returns 400. To change which workspaces such a destination covers, update its `workspaces`.

See the [OpenTelemetry export guide](https://platform.claude.com/docs/en/manage-claude/opentelemetry?sdk_languages=php#choose-workspaces-for-a-destination) to learn more about choosing the workspaces of a destination.

## Parameters

- `destinationID: string` (path parameter)

  ID of the destination (`tdst_...`).

- `workspaceID: string` (path parameter)

  ID of the workspace to add (`wrkspc_...`).

- `betas?: optional list<AnthropicBeta>` (header parameter)

  This endpoint is in beta: requests must send `telemetry-destinations-2026-08-11` in this header.

## Returns

- `class BetaTelemetryDestinationWorkspace`

  - `"telemetry_destination_workspace" type`

  - `\Datetime createdAt`

    Time the workspace was added to the list.

  - `string telemetryDestinationID`

    ID of the telemetry destination (`tdst_...`).

  - `string workspaceID`

    ID of the workspace (`wrkspc_...`).

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;
use Anthropic\Beta\AnthropicBeta;

$client = new Client(apiKey: 'my-anthropic-api-key');

$betaTelemetryDestinationWorkspace = $client
  ->beta
  ->organization
  ->telemetryDestinations
  ->workspaces
  ->add(
  'workspace_id',
  destinationID: 'destination_id',
  betas: [AnthropicBeta::MESSAGE_BATCHES_2024_09_24],
);

var_dump($betaTelemetryDestinationWorkspace);
```
