Slack via ClawLink

Work with Slack from chat — send messages, search conversations, manage channels, upload files, schedule messages, and more.

Powered by ClawLink, an integration hub for OpenClaw that handles hosted connection flows and credentials so you don't need to configure Slack API access yourself.

Quick start

1. Install the verified ClawLink plugin: openclaw plugins install clawhub:clawlink-plugin
2. Start a fresh OpenClaw chat if the plugin was just installed and ClawLink tools are not visible yet
3. If ClawLink is not configured, call clawlink_begin_pairing
4. Tell the user to open the returned pairing URL, sign in to ClawLink if needed, and approve the device
5. After the user confirms approval, call clawlink_get_pairing_status
6. Tell the user to connect Slack at claw-link.dev/dashboard?add=slack
7. When the user confirms Slack is connected, call clawlink_list_integrations and then clawlink_list_tools with the slack integration slug

Setup details

Installing the plugin

If the ClawLink plugin is not installed yet, tell the user to run:

openclaw plugins install clawhub:clawlink-plugin

If the current chat started before the plugin was installed and ClawLink tools are still unavailable, tell the user to start a fresh chat so OpenClaw reloads the plugin tool catalog.

Pairing ClawLink

If ClawLink reports that the plugin is not configured, the plugin has not been paired with the user's ClawLink account yet.

1. Call clawlink_begin_pairing.
2. Tell the user to open the returned pairing URL in their browser.
3. The user signs in to ClawLink if needed and approves the OpenClaw device.
4. After the user confirms approval, call clawlink_get_pairing_status to finish local setup.

The resulting device credential is stored locally in OpenClaw's plugin config and is only sent to claw-link.dev. The user should not paste raw credentials into chat.

Connecting Slack

Tell the user to open https://claw-link.dev/dashboard?add=slack and connect Slack there. The page opens the add-connection panel filtered to Slack. ClawLink's hosted page runs the Slack OAuth flow — the user clicks through the Slack login and authorization screen. When they confirm it is done, call clawlink_list_integrations to verify, then call clawlink_list_tools with integration slack.

Using Slack tools

ClawLink provides tools dynamically based on what the user has connected. You do not need to know tool names or schemas in advance.

Discovery

1. Call clawlink_list_integrations to confirm Slack is connected.
2. Call clawlink_list_tools with integration slack.
3. Treat the returned list as the source of truth. Do not guess or assume what tools exist.
4. If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration slack.
5. If no Slack tools appear, direct the user to https://claw-link.dev/dashboard?add=slack.

Execution

1. Call clawlink_describe_tool before using an unfamiliar tool, before any write, or when the request is ambiguous.
2. Use the returned schema, whenToUse, askBefore, safeDefaults, examples, and followups.
3. Prefer read, list, search, and get operations before writes.
4. For writes or anything marked as requiring confirmation, call clawlink_preview_tool first, then confirm with the user.
5. Execute with clawlink_call_tool.
6. If it fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

What you can do

Typical Slack tasks (actual availability depends on the user's connected account, permissions, scopes, and current ClawLink tool catalog):

• Send messages to channels and DMs
• Schedule delayed messages
• Search messages and conversations
• Create and archive channels
• Invite users to channels
• Upload and manage files
• Add emoji reactions
• Manage reminders and pinned items

Rules

• Always use ClawLink tools for Slack. Do not ask the user for separate Slack credentials.
• Do not claim a capability is missing without checking the live ClawLink catalog in the current turn.
• Do not invent slash commands or ask the user to paste raw credentials.
• Ask for confirmation before destructive, external-facing, or bulk write actions.
• If Slack is not connected, direct the user to https://claw-link.dev/dashboard?add=slack.
• Never echo or repeat the user's ClawLink credential.
