# Slack Workspaces

## List Slack Workspaces

**GET** `/v1/organizations/claude_tag/slack_workspaces`

List the set-up Slack workspaces the organization owns, newest first by `created_at`. Pass `slack_workspace_id` to look one workspace up by its Slack identifier: `data` then holds that workspace, or is empty when it is not set up. A workspace of a Slack Enterprise Grid the organization has connected returns 404 until it is set up. With `include_inherited=true` each workspace's `settings` holds what applies in it, and the request fails with 503 rather than resolve against a settings level that could not be read. A `page` cursor resumes only a request with the same `include_inherited`.

### Query parameters

- `include_inherited: optional boolean`

  When `true`, `settings` holds what applies in each workspace once the organization's Slack defaults are taken into account, and every member of `sources` names the level a value comes from. When `false` or left out, `settings` holds what each workspace itself stores.

- `limit: optional number`

  Number of items to return per page, between 1 and 100. Defaults to 20.

  format: int32

- `page: optional string`

  Opaque cursor from a previous response's `next_page`.

- `slack_workspace_id: optional string`

  Slack's identifier for one workspace, as in the workspace object's `slack.workspace_id`, not its `id`. With it `data` holds that workspace alone, or nothing when it is not set up.

### Headers

- `"anthropic-version": optional string`

  The version of the Claude API you want to use.

  Read more about versioning and our version history [here](https://platform.claude.com/docs/en/api/versioning?sdk_languages=http).

- `"anthropic-beta": optional array of AnthropicBeta`

  This endpoint is in beta: requests must send `experimental-claude-tag-2026-10-21` in this header.

### Returns

- `data: array of BetaClaudeTagSlackWorkspace`

  Workspaces on this page, newest first.

  - `type: "slack_workspace"`

  - `id: string`

    The workspace's identifier. Starts with `slws_`. It does not change for as long as the workspace is set up. A workspace that is removed and set up again has a new one, and the old one keeps returning 404; look the workspace up by its Slack identifier for the new one.

  - `created_at: string`

    Time the workspace was set up, by whichever route. It does not change for as long as `id` does not.

    format: date-time

  - `settings: BetaClaudeTagSettings`

    What the workspace itself stores or, with `include_inherited`, what applies in it. `sources` says which.

    - `enabled: boolean or null`

      Whether Claude is on. The nearest settings level that sets it decides.

    - `environment_id: string or null`

      The environment Claude's sessions run in, starting with `env_`, or the identifier of a self-hosted runner pool, starting with `ccpool_`. The nearest settings level that sets it decides.

    - `guest_policy: BetaClaudeTagGuestPolicy or null`

      What Claude does in a channel while a Slack guest is in it. The nearest settings level that sets it decides.

      - `BetaClaudeTagGuestPolicyAllow object`

        Claude answers in the channel.

        - `type: "allow"`

      - `BetaClaudeTagGuestPolicyRestrict object`

        Claude does not answer in the channel.

        - `type: "restrict"`

      - `BetaClaudeTagGuestPolicyChannelOnly object`

        Claude answers with only the Bundles attached to the channel itself.

        - `type: "channel_only"`

    - `instructions: string or null`

      Instructions for Claude. Instructions add up: the text of every settings level that sets it is joined, broadest first.

    - `model: string or null`

      The model Claude uses: a model identifier or the name of a model line. The nearest settings level that sets it decides. When none does, Claude uses the product's default model.

  - `slack: BetaClaudeTagSlackWorkspaceIdentifiers`

    Slack's own identifier for the workspace.

    - `workspace_id: string`

      Slack's identifier for the workspace, starting with `T`, such as `T0123ABCD`.

  - `sources: BetaClaudeTagSettingSources`

    For each setting, the settings level its value in `settings` comes from.

    - `enabled: BetaClaudeTagSettingSource or null`

      The settings level `enabled` comes from.

      - `BetaClaudeTagSlackChannelSettingSource object`

        The value comes from the addressed Slack channel itself.

        - `type: "slack_channel"`

        - `slack_channel_id: string`

          The channel's identifier, starting with `slch_`.

      - `BetaClaudeTagSlackWorkspaceSettingSource object`

        The value comes from a Slack workspace of the organization.

        - `type: "slack_workspace"`

        - `slack_workspace_id: string`

          The workspace's identifier, starting with `slws_`.

      - `BetaClaudeTagSlackParentChannelSettingSource object`

        The value comes from the channel that a code channel was started from. A parent channel contributes `instructions` and `environment_id` only.

        - `type: "slack_parent_channel"`

        - `slack_channel_id: string`

          The parent channel's identifier, starting with `slch_`.

      - `BetaClaudeTagSlackDefaultSettingSource object`

        The value comes from the organization's Slack defaults, which have no identifier.

        - `type: "slack_default"`

      - `BetaClaudeTagDefaultSettingSource object`

        No settings level sets a value, and the built-in default applies.

        - `type: "default"`

      - `BetaClaudeTagSlackGridChannelSettingSource object`

        The value comes from the addressed channel as it is set up under another workspace of its Enterprise Grid: a channel shared across the Grid keeps one Slack channel identifier in every workspace that sees it.

        - `type: "slack_grid_channel"`

        - `slack: BetaClaudeTagSlackChannelIdentifiers`

          Slack's own identifiers for the channel under that other workspace.

            Slack's identifier for the workspace the channel is in, starting with `T`, such as `T0123ABCD`.

            minLength: 2, maxLength: 32

    - `environment_id: BetaClaudeTagSettingSource or null`

      The settings level `environment_id` comes from.
