--- summary: "Slack setup and runtime behavior (Socket Mode + HTTP Request URLs)" read_when: - Setting up Slack or debugging Slack socket/HTTP mode title: "Slack" --- # Slack Status: production-ready for DMs + channels via Slack app integrations. Default mode is Socket Mode; HTTP Request URLs are also supported. Slack DMs default to pairing mode. Native command behavior and command catalog. Cross-channel diagnostics and repair playbooks. ## Quick setup In Slack app settings press the **[Create New App](https://api.slack.com/apps/new)** button: - choose **from a manifest** and select a workspace for your app - paste the [example manifest](#manifest-and-scope-checklist) from below and continue to create - generate an **App-Level Token** (`xapp-...`) with `connections:write` - install app and copy the **Bot Token** (`xoxb-...`) shown ```json5 { channels: { slack: { enabled: true, mode: "socket", appToken: "xapp-...", botToken: "xoxb-...", }, }, } ``` Env fallback (default account only): ```bash SLACK_APP_TOKEN=xapp-... SLACK_BOT_TOKEN=xoxb-... ``` ```bash openclaw gateway ``` In Slack app settings press the **[Create New App](https://api.slack.com/apps/new)** button: - choose **from a manifest** and select a workspace for your app - paste the [example manifest](#manifest-and-scope-checklist) and update the URLs before create - save the **Signing Secret** for request verification - install app and copy the **Bot Token** (`xoxb-...`) shown ```json5 { channels: { slack: { enabled: true, mode: "http", botToken: "xoxb-...", signingSecret: "your-signing-secret", webhookPath: "/slack/events", }, }, } ``` Use unique webhook paths for multi-account HTTP Give each account a distinct `webhookPath` (default `/slack/events`) so registrations do not collide. ```bash openclaw gateway ``` ## Manifest and scope checklist ```json { "display_information": { "name": "OpenClaw", "description": "Slack connector for OpenClaw" }, "features": { "bot_user": { "display_name": "OpenClaw", "always_online": true }, "app_home": { "messages_tab_enabled": true, "messages_tab_read_only_enabled": false }, "slash_commands": [ { "command": "/openclaw", "description": "Send a message to OpenClaw", "should_escape": false } ] }, "oauth_config": { "scopes": { "bot": [ "app_mentions:read", "assistant:write", "channels:history", "channels:read", "chat:write", "commands", "emoji:read", "files:read", "files:write", "groups:history", "groups:read", "im:history", "im:read", "im:write", "mpim:history", "mpim:read", "mpim:write", "pins:read", "pins:write", "reactions:read", "reactions:write", "users:read" ] } }, "settings": { "socket_mode_enabled": true, "event_subscriptions": { "bot_events": [ "app_mention", "channel_rename", "member_joined_channel", "member_left_channel", "message.channels", "message.groups", "message.im", "message.mpim", "pin_added", "pin_removed", "reaction_added", "reaction_removed" ] } } } ``` ```json { "display_information": { "name": "OpenClaw", "description": "Slack connector for OpenClaw" }, "features": { "bot_user": { "display_name": "OpenClaw", "always_online": true }, "app_home": { "messages_tab_enabled": true, "messages_tab_read_only_enabled": false }, "slash_commands": [ { "command": "/openclaw", "description": "Send a message to OpenClaw", "should_escape": false, "url": "https://gateway-host.example.com/slack/events" } ] }, "oauth_config": { "scopes": { "bot": [ "app_mentions:read", "assistant:write", "channels:history", "channels:read", "chat:write", "commands", "emoji:read", "files:read", "files:write", "groups:history", "groups:read", "im:history", "im:read", "im:write", "mpim:history", "mpim:read", "mpim:write", "pins:read", "pins:write", "reactions:read", "reactions:write", "users:read" ] } }, "settings": { "event_subscriptions": { "request_url": "https://gateway-host.example.com/slack/events", "bot_events": [ "app_mention", "channel_rename", "member_joined_channel", "member_left_channel", "message.channels", "message.groups", "message.im", "message.mpim", "pin_added", "pin_removed", "reaction_added", "reaction_removed" ] }, "interactivity": { "is_enabled": true, "request_url": "https://gateway-host.example.com/slack/events", "message_menu_options_url": "https://gateway-host.example.com/slack/events" } } } ``` Add the `chat:write.customize` bot scope if you want outgoing messages to use the active agent identity (custom username and icon) instead of the default Slack app identity. If you use an emoji icon, Slack expects `:emoji_name:` syntax. If you configure `channels.slack.userToken`, typical read scopes are: - `channels:history`, `groups:history`, `im:history`, `mpim:history` - `channels:read`, `groups:read`, `im:read`, `mpim:read` - `users:read` - `reactions:read` - `pins:read` - `emoji:read` - `search:read` (if you depend on Slack search reads) ## Token model - `botToken` + `appToken` are required for Socket Mode. - HTTP mode requires `botToken` + `signingSecret`. - `botToken`, `appToken`, `signingSecret`, and `userToken` accept plaintext strings or SecretRef objects. - Config tokens override env fallback. - `SLACK_BOT_TOKEN` / `SLACK_APP_TOKEN` env fallback applies only to the default account. - `userToken` (`xoxp-...`) is config-only (no env fallback) and defaults to read-only behavior (`userTokenReadOnly: true`). Status snapshot behavior: - Slack account inspection tracks per-credential `*Source` and `*Status` fields (`botToken`, `appToken`, `signingSecret`, `userToken`). - Status is `available`, `configured_unavailable`, or `missing`. - `configured_unavailable` means the account is configured through SecretRef or another non-inline secret source, but the current command/runtime path could not resolve the actual value. - In HTTP mode, `signingSecretStatus` is included; in Socket Mode, the required pair is `botTokenStatus` + `appTokenStatus`. For actions/directory reads, user token can be preferred when configured. For writes, bot token remains preferred; user-token writes are only allowed when `userTokenReadOnly: false` and bot token is unavailable. ## Actions and gates Slack actions are controlled by `channels.slack.actions.*`. Available action groups in current Slack tooling: | Group | Default | | ---------- | ------- | | messages | enabled | | reactions | enabled | | pins | enabled | | memberInfo | enabled | | emojiList | enabled | Current Slack message actions include `send`, `upload-file`, `download-file`, `read`, `edit`, `delete`, `pin`, `unpin`, `list-pins`, `member-info`, and `emoji-list`. ## Access control and routing `channels.slack.dmPolicy` controls DM access (legacy: `channels.slack.dm.policy`): - `pairing` (default) - `allowlist` - `open` (requires `channels.slack.allowFrom` to include `"*"`; legacy: `channels.slack.dm.allowFrom`) - `disabled` DM flags: - `dm.enabled` (default true) - `channels.slack.allowFrom` (preferred) - `dm.allowFrom` (legacy) - `dm.groupEnabled` (group DMs default false) - `dm.groupChannels` (optional MPIM allowlist) Multi-account precedence: - `channels.slack.accounts.default.allowFrom` applies only to the `default` account. - Named accounts inherit `channels.slack.allowFrom` when their own `allowFrom` is unset. - Named accounts do not inherit `channels.slack.accounts.default.allowFrom`. Pairing in DMs uses `openclaw pairing approve slack `. `channels.slack.groupPolicy` controls channel handling: - `open` - `allowlist` - `disabled` Channel allowlist lives under `channels.slack.channels` and should use stable channel IDs. Runtime note: if `channels.slack` is completely missing (env-only setup), runtime falls back to `groupPolicy="allowlist"` and logs a warning (even if `channels.defaults.groupPolicy` is set). Name/ID resolution: - channel allowlist entries and DM allowlist entries are resolved at startup when token access allows - unresolved channel-name entries are kept as configured but ignored for routing by default - inbound authorization and channel routing are ID-first by default; direct username/slug matching requires `channels.slack.dangerouslyAllowNameMatching: true` Channel messages are mention-gated by default. Mention sources: - explicit app mention (`<@botId>`) - mention regex patterns (`agents.list[].groupChat.mentionPatterns`, fallback `messages.groupChat.mentionPatterns`) - implicit reply-to-bot thread behavior (disabled when `thread.requireExplicitMention` is `true`) Per-channel controls (`channels.slack.channels.`; names only via startup resolution or `dangerouslyAllowNameMatching`): - `requireMention` - `users` (allowlist) - `allowBots` - `skills` - `systemPrompt` - `tools`, `toolsBySender` - `toolsBySender` key format: `id:`, `e164:`, `username:`, `name:`, or `"*"` wildcard (legacy unprefixed keys still map to `id:` only) ## Threading, sessions, and reply tags - DMs route as `direct`; channels as `channel`; MPIMs as `group`. - With default `session.dmScope=main`, Slack DMs collapse to agent main session. - Channel sessions: `agent::slack:channel:`. - Thread replies can create thread session suffixes (`:thread:`) when applicable. - `channels.slack.thread.historyScope` default is `thread`; `thread.inheritParent` default is `false`. - `channels.slack.thread.initialHistoryLimit` controls how many existing thread messages are fetched when a new thread session starts (default `20`; set `0` to disable). - `channels.slack.thread.requireExplicitMention` (default `false`): when `true`, suppress implicit thread mentions so the bot only responds to explicit `@bot` mentions inside threads, even when the bot already participated in the thread. Without this, replies in a bot-participated thread bypass `requireMention` gating. Reply threading controls: - `channels.slack.replyToMode`: `off|first|all|batched` (default `off`) - `channels.slack.replyToModeByChatType`: per `direct|group|channel` - legacy fallback for direct chats: `channels.slack.dm.replyToMode` Manual reply tags are supported: - `[[reply_to_current]]` - `[[reply_to:]]` Note: `replyToMode="off"` disables **all** reply threading in Slack, including explicit `[[reply_to_*]]` tags. This differs from Telegram, where explicit tags are still honored in `"off"` mode. The difference reflects the platform threading models: Slack threads hide messages from the channel, while Telegram replies remain visible in the main chat flow. ## Ack reactions `ackReaction` sends an acknowledgement emoji while OpenClaw is processing an inbound message. Resolution order: - `channels.slack.accounts..ackReaction` - `channels.slack.ackReaction` - `messages.ackReaction` - agent identity emoji fallback (`agents.list[].identity.emoji`, else "👀") Notes: - Slack expects shortcodes (for example `"eyes"`). - Use `""` to disable the reaction for the Slack account or globally. ## Text streaming `channels.slack.streaming` controls live preview behavior: - `off`: disable live preview streaming. - `partial` (default): replace preview text with the latest partial output. - `block`: append chunked preview updates. - `progress`: show progress status text while generating, then send final text. `channels.slack.streaming.nativeTransport` controls Slack native text streaming when `channels.slack.streaming.mode` is `partial` (default: `true`). - A reply thread must be available for native text streaming and Slack assistant thread status to appear. Thread selection still follows `replyToMode`. - Channel and group-chat roots can still use the normal draft preview when native streaming is unavailable. - Top-level Slack DMs stay off-thread by default, so they do not show the thread-style preview; use thread replies or `typingReaction` if you want visible progress there. - Media and non-text payloads fall back to normal delivery. - If streaming fails mid-reply, OpenClaw falls back to normal delivery for remaining payloads. Use draft preview instead of Slack native text streaming: ```json5 { channels: { slack: { streaming: { mode: "partial", nativeTransport: false, }, }, }, } ``` Legacy keys: - `channels.slack.streamMode` (`replace | status_final | append`) is auto-migrated to `channels.slack.streaming.mode`. - boolean `channels.slack.streaming` is auto-migrated to `channels.slack.streaming.mode` and `channels.slack.streaming.nativeTransport`. - legacy `channels.slack.nativeStreaming` is auto-migrated to `channels.slack.streaming.nativeTransport`. ## Typing reaction fallback `typingReaction` adds a temporary reaction to the inbound Slack message while OpenClaw is processing a reply, then removes it when the run finishes. This is most useful outside of thread replies, which use a default "is typing..." status indicator. Resolution order: - `channels.slack.accounts..typingReaction` - `channels.slack.typingReaction` Notes: - Slack expects shortcodes (for example `"hourglass_flowing_sand"`). - The reaction is best-effort and cleanup is attempted automatically after the reply or failure path completes. ## Media, chunking, and delivery Slack file attachments are downloaded from Slack-hosted private URLs (token-authenticated request flow) and written to the media store when fetch succeeds and size limits permit. Runtime inbound size cap defaults to `20MB` unless overridden by `channels.slack.mediaMaxMb`. - text chunks use `channels.slack.textChunkLimit` (default 4000) - `channels.slack.chunkMode="newline"` enables paragraph-first splitting - file sends use Slack upload APIs and can include thread replies (`thread_ts`) - outbound media cap follows `channels.slack.mediaMaxMb` when configured; otherwise channel sends use MIME-kind defaults from media pipeline Preferred explicit targets: - `user:` for DMs - `channel:` for channels Slack DMs are opened via Slack conversation APIs when sending to user targets. ## Commands and slash behavior - Native command auto-mode is **off** for Slack (`commands.native: "auto"` does not enable Slack native commands). - Enable native Slack command handlers with `channels.slack.commands.native: true` (or global `commands.native: true`). - When native commands are enabled, register matching slash commands in Slack (`/` names), with one exception: - register `/agentstatus` for the status command (Slack reserves `/status`) - If native commands are not enabled, you can run a single configured slash command via `channels.slack.slashCommand`. - Native arg menus now adapt their rendering strategy: - up to 5 options: button blocks - 6-100 options: static select menu - more than 100 options: external select with async option filtering when interactivity options handlers are available - if encoded option values exceed Slack limits, the flow falls back to buttons - For long option payloads, Slash command argument menus use a confirm dialog before dispatching a selected value. Default slash command settings: - `enabled: false` - `name: "openclaw"` - `sessionPrefix: "slack:slash"` - `ephemeral: true` Slash sessions use isolated keys: - `agent::slack:slash:` and still route command execution against the target conversation session (`CommandTargetSessionKey`). ## Interactive replies Slack can render agent-authored interactive reply controls, but this feature is disabled by default. Enable it globally: ```json5 { channels: { slack: { capabilities: { interactiveReplies: true, }, }, }, } ``` Or enable it for one Slack account only: ```json5 { channels: { slack: { accounts: { ops: { capabilities: { interactiveReplies: true, }, }, }, }, }, } ``` When enabled, agents can emit Slack-only reply directives: - `[[slack_buttons: Approve:approve, Reject:reject]]` - `[[slack_select: Choose a target | Canary:canary, Production:production]]` These directives compile into Slack Block Kit and route clicks or selections back through the existing Slack interaction event path. Notes: - This is Slack-specific UI. Other channels do not translate Slack Block Kit directives into their own button systems. - The interactive callback values are OpenClaw-generated opaque tokens, not raw agent-authored values. - If generated interactive blocks would exceed Slack Block Kit limits, OpenClaw falls back to the original text reply instead of sending an invalid blocks payload. ## Exec approvals in Slack Slack can act as a native approval client with interactive buttons and interactions, instead of falling back to the Web UI or terminal. - Exec approvals use `channels.slack.execApprovals.*` for native DM/channel routing. - Plugin approvals can still resolve through the same Slack-native button surface when the request already lands in Slack and the approval id kind is `plugin:`. - Approver authorization is still enforced: only users identified as approvers can approve or deny requests through Slack. This uses the same shared approval button surface as other channels. When `interactivity` is enabled in your Slack app settings, approval prompts render as Block Kit buttons directly in the conversation. When those buttons are present, they are the primary approval UX; OpenClaw should only include a manual `/approve` command when the tool result says chat approvals are unavailable or manual approval is the only path. Config path: - `channels.slack.execApprovals.enabled` - `channels.slack.execApprovals.approvers` (optional; falls back to `commands.ownerAllowFrom` when possible) - `channels.slack.execApprovals.target` (`dm` | `channel` | `both`, default: `dm`) - `agentFilter`, `sessionFilter` Slack auto-enables native exec approvals when `enabled` is unset or `"auto"` and at least one approver resolves. Set `enabled: false` to disable Slack as a native approval client explicitly. Set `enabled: true` to force native approvals on when approvers resolve. Default behavior with no explicit Slack exec approval config: ```json5 { commands: { ownerAllowFrom: ["slack:U12345678"], }, } ``` Explicit Slack-native config is only needed when you want to override approvers, add filters, or opt into origin-chat delivery: ```json5 { channels: { slack: { execApprovals: { enabled: true, approvers: ["U12345678"], target: "both", }, }, }, } ``` Shared `approvals.exec` forwarding is separate. Use it only when exec approval prompts must also route to other chats or explicit out-of-band targets. Shared `approvals.plugin` forwarding is also separate; Slack-native buttons can still resolve plugin approvals when those requests already land in Slack. Same-chat `/approve` also works in Slack channels and DMs that already support commands. See [Exec approvals](/tools/exec-approvals) for the full approval forwarding model. ## Events and operational behavior - Message edits/deletes/thread broadcasts are mapped into system events. - Reaction add/remove events are mapped into system events. - Member join/leave, channel created/renamed, and pin add/remove events are mapped into system events. - `channel_id_changed` can migrate channel config keys when `configWrites` is enabled. - Channel topic/purpose metadata is treated as untrusted context and can be injected into routing context. - Thread starter and initial thread-history context seeding are filtered by configured sender allowlists when applicable. - Block actions and modal interactions emit structured `Slack interaction: ...` system events with rich payload fields: - block actions: selected values, labels, picker values, and `workflow_*` metadata - modal `view_submission` and `view_closed` events with routed channel metadata and form inputs ## Configuration reference pointers Primary reference: - [Configuration reference - Slack](/gateway/configuration-reference#slack) High-signal Slack fields: - mode/auth: `mode`, `botToken`, `appToken`, `signingSecret`, `webhookPath`, `accounts.*` - DM access: `dm.enabled`, `dmPolicy`, `allowFrom` (legacy: `dm.policy`, `dm.allowFrom`), `dm.groupEnabled`, `dm.groupChannels` - compatibility toggle: `dangerouslyAllowNameMatching` (break-glass; keep off unless needed) - channel access: `groupPolicy`, `channels.*`, `channels.*.users`, `channels.*.requireMention` - threading/history: `replyToMode`, `replyToModeByChatType`, `thread.*`, `historyLimit`, `dmHistoryLimit`, `dms.*.historyLimit` - delivery: `textChunkLimit`, `chunkMode`, `mediaMaxMb`, `streaming`, `streaming.nativeTransport` - ops/features: `configWrites`, `commands.native`, `slashCommand.*`, `actions.*`, `userToken`, `userTokenReadOnly` ## Troubleshooting Check, in order: - `groupPolicy` - channel allowlist (`channels.slack.channels`) - `requireMention` - per-channel `users` allowlist Useful commands: ```bash openclaw channels status --probe openclaw logs --follow openclaw doctor ``` Check: - `channels.slack.dm.enabled` - `channels.slack.dmPolicy` (or legacy `channels.slack.dm.policy`) - pairing approvals / allowlist entries ```bash openclaw pairing list slack ``` Validate bot + app tokens and Socket Mode enablement in Slack app settings. If `openclaw channels status --probe --json` shows `botTokenStatus` or `appTokenStatus: "configured_unavailable"`, the Slack account is configured but the current runtime could not resolve the SecretRef-backed value. Validate: - signing secret - webhook path - Slack Request URLs (Events + Interactivity + Slash Commands) - unique `webhookPath` per HTTP account If `signingSecretStatus: "configured_unavailable"` appears in account snapshots, the HTTP account is configured but the current runtime could not resolve the SecretRef-backed signing secret. Verify whether you intended: - native command mode (`channels.slack.commands.native: true`) with matching slash commands registered in Slack - or single slash command mode (`channels.slack.slashCommand.enabled: true`) Also check `commands.useAccessGroups` and channel/user allowlists. ## Related - [Pairing](/channels/pairing) - [Groups](/channels/groups) - [Security](/gateway/security) - [Channel routing](/channels/channel-routing) - [Troubleshooting](/channels/troubleshooting) - [Configuration](/gateway/configuration) - [Slash commands](/tools/slash-commands)
