# Update Slack Channel

**POST** `/v1/organizations/claude_tag/slack_channels/{id}`

Change the settings a Slack channel stores. The update is partial: a setting left out is unchanged, and a setting sent as null is cleared, so the channel inherits it. If any value is refused, no setting in the request is stored. A group direct message takes no settings and returns 400.

## Path parameters

- `id: string`

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

## 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.

## Body parameters

- `settings: BetaClaudeTagSettingsUpdate`

  The settings to change.

  - `enabled: optional boolean or null`

    Whether Claude is on. `true` on a channel turns Claude on in it even when its workspace stores `false`. Null clears it.

  - `environment_id: optional string or null`

    The environment Claude's sessions run in: the identifier of an active environment of the organization, starting with `env_`. Null clears it.

    minLength: 1, maxLength: 64

  - `guest_policy: optional BetaClaudeTagGuestPolicy or null`

    What Claude does in a channel while a Slack guest is in it. Null clears it.

    - `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: optional string or null`

    Instructions for Claude, up to 8,192 characters after leading and trailing white space is trimmed. Null or blank text clears them.

  - `model: optional string or null`

    The model Claude uses: the identifier of a model, or the name of a model line, that the organization is entitled to for Claude Tag. Null clears it.

    minLength: 1, maxLength: 128

## Returns

- `BetaClaudeTagSlackChannel object`

  A Slack channel set up for Claude Tag, with the settings it stores or, with `include_inherited`, the settings that apply in it.

  - `type: "slack_channel"`

  - `id: string`

    The channel's identifier. Starts with `slch_`. It does not change for as long as the channel is set up, with one exception: a channel that is not configured gets a new one when claude.ai replaces its record, which happens only while the organization's read-only mode is off. A channel that is removed and set up again also has a new one. The old one keeps returning 404; look the channel up by its Slack identifiers for the new one.

  - `created_at: string`

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

    format: date-time

  - `settings: BetaClaudeTagSettings`

    What the channel 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.

  - `sources: BetaClaudeTagSettingSources`

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

        - `type: "slack_workspace"`

        - `slack_workspace_id: string`

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

      - `BetaClaudeTagSlackParentChannelSettingSource object`
