# Attach Bundle

**POST** `/v1/organizations/claude_tag/bundles/{bundle_id}/targets`

Attach a Bundle to a Slack channel or a Slack workspace. A Bundle attached to a workspace can be used in the workspace and in every channel in it. Attaching a Bundle to a channel or workspace it is already attached to returns the existing Bundle Target. The channel or workspace must be set up: attaching never sets a channel up. A group direct message takes no Bundle and returns 400.

## Path parameters

- `bundle_id: string`

  The Bundle's identifier, starting with `capp_`.

## 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.

      minLength: 8, maxLength: 64

  - `BetaClaudeTagSlackWorkspaceBundleTargetCreate object`

    Attach the Bundle to a Slack workspace.

    - `type: "slack_workspace"`

  One Bundle attached to one Slack channel or one Slack workspace. More types of target can be added.
