# List Telemetry Destination Workspaces

`$client->beta->organization->telemetryDestinations->workspaces->list(string destinationID, ?int limit, ?string page, ?list<AnthropicBeta> betas): PageCursor<BetaTelemetryDestinationWorkspace>`

**GET** `/v1/organizations/telemetry_destinations/{destination_id}/workspaces`

List the workspaces on a destination's workspace list, newest entry first.

A destination whose `workspaces.type` is `all` doesn't have a list, so its page is empty. The list includes archived 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_...`).

- `limit?: optional int` (query parameter)

  Number of entries to return per page, between 1 and 1,000. Defaults to 20.

- `page?: optional string` (query parameter)

  Opaque cursor from a previous response's `next_page`. Leave it out to get the first page.

- `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');

$page = $client->beta->organization->telemetryDestinations->workspaces->list(
  'destination_id',
  limit: 0,
  page: 'page',
  betas: [AnthropicBeta::MESSAGE_BATCHES_2024_09_24],
);

var_dump($page);
```
