## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `SLACKBOT_ADD_CALL_PARTICIPANTS` | Add call participants | Registers new participants added to a Slack call. |
| `SLACKBOT_ADD_REACTION_TO_AN_ITEM` | Add reaction to message | Adds a specified emoji reaction to an existing message in a Slack channel, identified by its timestamp; does not remove or retrieve reactions. |
| `SLACKBOT_ADD_A_REMOTE_FILE_FROM_A_SERVICE` | Add a remote file | Adds a reference to an external file (e.g., Google Drive, Dropbox) to Slack for discovery and sharing, requiring a unique `external_id` and an `external_url` accessible by Slack. |
| `SLACKBOT_ARCHIVE_CONVERSATION` | Archive a Slack conversation | Archives a Slack conversation by its ID, rendering it read-only and hidden while retaining history, ideal for cleaning up inactive channels; be aware that some channels (like #general or certain DMs) cannot be archived and this may impact connected integrations. |
| `SLACKBOT_CLOSE_DM` | Close conversation channel | Closes a Slack direct message (DM) or multi-person direct message (MPDM) channel, removing it from the user's sidebar without deleting history; this action affects only the calling user's view. |
| `SLACKBOT_CREATE_A_REMINDER` | Create a reminder | Creates a Slack reminder with specified text and time; time accepts Unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every Thursday at 2pm'). |
| `SLACKBOT_CREATE_CANVAS` | Create Slack Canvas | Creates a new Slack Canvas with the specified title and optional content. |
| `SLACKBOT_CREATE_CHANNEL` | Create channel | Initiates a public or private channel-based conversation in a Slack workspace. Immediately creates the channel; invoke only after explicit user confirmation. |
| `SLACKBOT_CREATE_USER_GROUP` | Create a Slack user group | Creates a new User Group (often referred to as a subteam) in a Slack workspace. |
| `SLACKBOT_CUSTOMIZE_URL_UNFURL` | Customize URL unfurl | Customizes URL previews (unfurling) in a specific Slack message using a URL-encoded JSON in `unfurls` to define custom content or remove existing previews. |
| `SLACKBOT_DELETE_CANVAS` | Delete Slack Canvas | Deletes a Slack Canvas permanently and irreversibly. Always confirm with the user before calling this tool. |
| `SLACKBOT_DELETE_FILE` | Delete a file by ID | Permanently deletes an existing file from a Slack workspace using its unique file ID; this action is irreversible and also removes any associated comments or shares. |
| `SLACKBOT_DELETE_FILE_COMMENT` | Delete file comment | Deletes a specific comment from a file in Slack; this action is irreversible. |
| `SLACKBOT_DELETE_REMINDER` | Delete a Slack reminder | Deletes an existing Slack reminder, typically when it is no longer relevant or a task is completed; this operation is irreversible. |
| `SLACKBOT_DELETES_A_MESSAGE_FROM_A_CHAT` | Delete a message from a chat | Deletes a message, identified by its channel ID and timestamp, from a Slack channel, private group, or direct message conversation; the authenticated user or bot must be the original poster. |
| `SLACKBOT_DELETE_SCHEDULED_MESSAGE` | Delete scheduled chat message | Deletes a pending, unsent scheduled message from the specified Slack channel, identified by its `scheduled_message_id`. |
| `SLACKBOT_DISABLE_USER_GROUP` | Disable a Slack user group | Disables a specified, currently enabled Slack User Group by its unique ID, effectively archiving it by setting its 'date_delete' timestamp; the group is not permanently deleted and can be re-enabled. |
| `SLACKBOT_DOWNLOAD_FILE` | Download Slack file | Tool to download Slack file content and convert it to a publicly accessible URL. Use when you need to retrieve and download files that have been shared in Slack channels or conversations. |
| `SLACKBOT_EDIT_CANVAS` | Edit Slack Canvas | Edits a Slack Canvas with granular control over content placement. Supports replace, insert (before/after/start/end) operations for flexible content management. |
| `SLACKBOT_ENABLE_PUBLIC_SHARING_OF_A_FILE` | Share file public url | Enables public sharing for an existing Slack file by generating a publicly accessible URL; this action does not create new files. Once enabled, the file is accessible to anyone with the URL — verify intent before sharing sensitive or confidential files. |
| `SLACKBOT_ENABLE_USER_GROUP` | Enable a user group | Enables a disabled User Group in Slack using its ID, reactivating it for mentions and permissions; this action only changes the enabled status and cannot create new groups or modify other properties. |
| `SLACKBOT_END_CALL` | End a call | Ends an ongoing Slack call, identified by its ID (obtained from `calls.add`), optionally specifying the call's duration. |
| `SLACKBOT_FETCH_CONVERSATION_HISTORY` | Fetch conversation history | Fetches a chronological list of messages and events from a specified Slack conversation, accessible by the authenticated user/bot, with options for pagination and time range filtering. IMPORTANT LIMITATION: This action only returns messages from the main channel timeline. Threaded replies are NOT returned by this endpoint. To retrieve threaded replies, use the SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION action (conversations.replies API) instead. The oldest/latest timestamp filters work reliably for filtering the main channel timeline, but cannot be used to retrieve individual threaded replies - even if you know the exact reply timestamp, setting oldest=latest to that timestamp will return an empty messages array. To get threaded replies: 1. Use this action to get parent messages (which include thread_ts, reply_count, latest_reply fields) 2. Use SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION with the parent's thread_ts to fetch all replies in that thread |
| `SLACKBOT_FETCH_ITEM_REACTIONS` | Fetch item reactions | Fetches reactions for a Slack message, file, or file comment. Exactly one identifier path must be provided: `channel`+`timestamp`, `file`, or `file_comment`. Mixing identifiers (e.g., providing both `channel`+`timestamp` and `file`) causes errors. If the response omits the `reactions` field, the item has zero reactions. |
| `SLACKBOT_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION` | Retrieve conversation replies | Retrieves replies to a specific parent message in a Slack conversation, using the channel ID and the parent message's timestamp (`ts`). Note: The parent message in the response contains metadata (reply_count, reply_users, latest_reply) that indicates expected thread activity. If the returned messages array contains fewer replies than reply_count indicates, check: (1) has_more=true means pagination is needed, (2) recently posted replies may have timing delays, (3) some replies may be filtered by permissions or deleted. The composio_execution_message field will warn about any detected mismatches. |
| `SLACKBOT_FETCH_TEAM_INFO` | Fetch team info | Fetches comprehensive metadata about the current Slack team, or a specified team if the provided ID is accessible. |
| `SLACKBOT_FIND_CHANNELS` | Find channels | Find channels in a Slack workspace by any criteria - name, topic, purpose, or description. Returns channel IDs (C*/G* prefixed) required by most Slack tools — always resolve names to IDs here before passing to other tools. NOTE: This action searches channels and conversations visible to the authenticated user. Empty results may indicate: - No channels match the search query in name, topic, or purpose - The target private channel or DM is not accessible to the authenticated user because they are not a member - The connection lacks required read scopes (channels:read, groups:read, im:read, mpim:read). If empty, retry with exact_match=false or exclude_archived=false to avoid false negatives. In large workspaces, paginate using next_cursor to avoid missing matches. Check 'composio_execution_message' and 'total_channels_searched' in the response for details. |
| `SLACKBOT_FIND_USER_BY_EMAIL_ADDRESS` | Lookup users by email | Retrieves the Slack user object for an active user by their registered email address; requires the users:read.email OAuth scope. Fails with 'users_not_found' if the email is unregistered, the user is inactive, the account is a guest, or the email is hidden by workspace privacy settings. |
| `SLACKBOT_FIND_USERS` | Find users | Find users in a Slack workspace by any criteria - email, name, display name, or other text. Includes optimized email lookup for exact email matches. Zero results may reflect email visibility restrictions or workspace policies, not global absence. Repeated calls may trigger HTTP 429; honor the Retry-After header. |
| `SLACKBOT_GET_BOT_USER` | Fetch bot user information | Fetches information for a specified, existing Slack bot user; will not work for regular user accounts or other integration types. |
| `SLACKBOT_GET_CALL_INFO` | Retrieve call information | Retrieves a point-in-time snapshot of a specific Slack call's information. |
| `SLACKBOT_GET_REMINDER` | Get reminder information | Retrieves detailed information for an existing Slack reminder specified by its ID; this is a read-only operation. |
| `SLACKBOT_GET_REMOTE_FILE` | Get remote file | Retrieve information about a remote file added to Slack via the files.remote API. Does not work for standard Slack-hosted file uploads. |
| `SLACKBOT_GET_TEAM_PROFILE` | Retrieve team profile details | Retrieves all profile field definitions for a Slack team, optionally filtered by visibility, to understand the team's profile structure. |
| `SLACKBOT_GET_USER_DND_STATUS` | Get team DND status | Retrieves a user's current Do Not Disturb status. |
| `SLACKBOT_GET_USER_PRESENCE` | Retrieve user presence | Retrieves a Slack user's current real-time presence (e.g., 'active', 'away') to determine their availability, noting this action does not provide historical data or status reasons. |
| `SLACKBOT_INVITE_USERS_TO_A_CHANNEL` | Invite users to a Slack channel | Invites users to an existing Slack channel using their valid Slack User IDs. Response is always HTTP 200; inspect `ok`, `error`, and `errors` fields to confirm users were added. |
| `SLACKBOT_JOIN_AN_EXISTING_CONVERSATION` | Join conversation by channel id | Joins an existing Slack conversation (public channel, private channel, or multi-person direct message) by its ID, if the authenticated user has permission. Joining an already-joined channel returns a non-fatal no-op response. Private or restricted channel joins may fail with a permission error. |
| `SLACKBOT_LEAVE_CONVERSATION` | Leave conversation channel | Leaves a Slack conversation given its channel ID; fails if leaving as the last member of a private channel or if used on a Slack Connect channel. |
| `SLACKBOT_LIST_ALL_CHANNELS` | List all channels | Lists conversations available to the user with various filters and search options. Always use resolved `channel_id` (not display names) for downstream operations, as names may be non-unique. The `created` field in results is a Unix epoch timestamp (UTC). Pagination across large workspaces may return HTTP 429 with a `Retry-After` header; honor the delay and resume from the last successful cursor. |
| `SLACKBOT_LIST_ALL_USERS` | List all users | Retrieves a paginated list of all users with profile details, status, and team memberships in a Slack workspace; data may not be real-time. Filter response fields `is_bot`, `is_app_user`, and `deleted` to build human-only rosters. Profile fields like `email` and `phone` may be absent depending on OAuth scopes and workspace privacy settings. Guest/restricted accounts may be omitted based on scopes—do not treat results as a complete directory. High-frequency calls risk HTTP 429; honor the `Retry-After` header and throttle to ~1–2 requests/second. Use stable user IDs rather than display names for mapping. Prefer SLACK_FIND_USERS for targeted lookups; cache results to avoid full-workspace fetches. |
| `SLACKBOT_LIST_CONVERSATIONS` | List conversations | List conversations (channels/DMs) accessible to a specified user (or the authenticated user if no user ID is provided), respecting shared membership for non-public channels. Returns conversation IDs (C* for channels, G* for group DMs), not display names. Absence of private channels, DMs, or MPIMs from results indicates token scope or membership limits, not that the conversation is nonexistent. |
| `SLACKBOT_LIST_CUSTOM_EMOJIS` | List team custom emojis | Retrieves all custom emojis for the Slack workspace (image URLs or aliases), not standard Unicode emojis; does not include usage statistics or creation dates. |
| `SLACKBOT_LIST_FILES_WITH_FILTERS_IN_SLACK` | List Slack files | Lists files and their metadata within a Slack workspace, filterable by user, channel, timestamp, or type; returns metadata only, not file content. Results are limited to files visible to the authenticated user — files in private channels or restricted to certain members require appropriate membership and permissions. For large workspaces, check `paging.pages` in the response to determine total pages when paginating. |
| `SLACKBOT_LIST_PINNED_ITEMS` | List pinned items in a channel | Retrieves all messages and files pinned to a specified channel; the caller must have access to this channel. |
| `SLACKBOT_LIST_REMINDERS` | List reminders | Lists all reminders with their details for the authenticated Slack user; returns an empty array if no reminders exist (valid state, not an error). Reminder text is not unique—perform client-side matching on returned objects before extracting a reminder ID for use with SLACK_DELETE_A_SLACK_REMINDER. |
| `SLACKBOT_LIST_REMOTE_FILES` | List remote files | Retrieve information about a team's remote files. |
| `SLACKBOT_LIST_USER_GROUP_MEMBERS` | List all users in a user group | Retrieves a list of all user IDs within a specified Slack user group, with an option to include users from disabled groups. |
| `SLACKBOT_LIST_USER_GROUPS` | List user groups | Lists user groups in a Slack workspace, including user-created and default groups; results for large workspaces may be paginated. |
| `SLACKBOT_LIST_USER_REACTIONS` | List user reactions | Lists all reactions added by a specific user to messages, files, or file comments in Slack, useful for engagement analysis when the item content itself is not required. Results are paginated; check `response_metadata.next_cursor` and iterate with the `cursor` parameter to retrieve complete reaction history. |
| `SLACKBOT_LOOKUP_CANVAS_SECTIONS` | Lookup Canvas Sections | Looks up section IDs in a Slack Canvas for use with targeted edit operations. Section IDs are needed for insert_after, insert_before, delete, and section-specific replace operations. |
| `SLACKBOT_OPEN_DM` | Open DM | Opens or resumes a Slack direct message (DM) or multi-person direct message (MPIM) by providing either user IDs or an existing channel ID. Returns `already_open=true` when the DM exists — treat as success and reuse the returned `channel.id` (starts with 'D') for subsequent SLACK_SEND_MESSAGE calls; passing a username, email, or user ID directly to SLACK_SEND_MESSAGE causes `channel_not_found`. Avoid redundant calls when an existing DM channel ID is available. |
| `SLACKBOT_PIN_ITEM` | Pin an item to a channel | Pins a message to a specified Slack channel; the message must not already be pinned. |
| `SLACKBOT_REMOVE_CALL_PARTICIPANTS` | Remove call participants | Registers participants removed from a Slack call. |
| `SLACKBOT_REMOVE_REACTION_FROM_ITEM` | Remove reaction from item | Removes an emoji reaction from a message, file, or file comment in Slack. Provide exactly one targeting method: channel+timestamp together, file, or file_comment. Mixing methods or omitting all returns invalid_arguments. |
| `SLACKBOT_REMOVE_REMOTE_FILE` | Remove remote file | Removes the Slack reference to an external file (which must have been previously added via the remote files API), specified by either its `external_id` or `file` ID (one of which is required), without deleting the actual external file. |
| `SLACKBOT_REMOVE_USER_FROM_CONVERSATION` | Remove user from conversation | Removes a specified user from a Slack conversation (channel); the caller must have permissions to remove users and cannot remove themselves using this action. |
| `SLACKBOT_RENAME_CONVERSATION` | Rename a conversation | Renames a Slack channel, automatically adjusting the new name to meet naming conventions (e.g., converting to lowercase), which may affect integrations using the old name. |
| `SLACKBOT_RETRIEVE_CONVERSATION_INFORMATION` | Retrieve conversation information | Retrieves metadata for a Slack conversation by ID (e.g., name, purpose, creation date, with options for member count/locale), excluding message content. The `channel` parameter is effectively required. Private channels, DMs, or channels where the app lacks membership may return restricted data; check `is_archived` and `is_member` fields in the response to diagnose access issues. Bulk lookups may trigger HTTP 429 rate limiting; honor the `Retry-After` response header. |
| `SLACKBOT_RETRIEVE_CONVERSATION_MEMBERS_LIST` | Get conversation members | Retrieves a paginated list of active member IDs (not names, emails, or presence) for a specified Slack public channel, private channel, DM, or MPIM. Returns only user IDs; use a user-lookup tool to enrich member data. |
| `SLACKBOT_RETRIEVE_CURRENT_USER_DND_STATUS` | Retrieve user DND status | Retrieves a Slack user's current Do Not Disturb (DND) status to determine their availability before interaction; any specified user ID must be a valid Slack user ID. |
| `SLACKBOT_RETRIEVE_DETAILED_INFORMATION_ABOUT_A_FILE` | Retrieve detailed file information | Retrieves detailed metadata and paginated comments for a specific Slack file ID; does not download file content. |
| `SLACKBOT_RETRIEVE_DETAILED_USER_INFORMATION` | Retrieve detailed user information | Retrieves comprehensive information for a valid Slack user ID, excluding message history and channel memberships. Sensitive fields like `email` and `phone` require the `users:read.email` scope and may be silently omitted based on workspace privacy policies. |
| `SLACKBOT_RETRIEVE_USER_PROFILE_INFORMATION` | Retrieve user profile information | Retrieves profile information for a specified Slack user (defaults to the authenticated user if `user` ID is omitted); a provided `user` ID must be valid. Sensitive fields like email and phone may be silently omitted if required scopes (e.g., `users:read.email`) are not granted or workspace privacy policies restrict access. |
| `SLACKBOT_REVOKE_FILE_PUBLIC_SHARING` | Revoke a file's public url | Revokes a Slack file's public URL, making it private; this is a no-op if not already public and is irreversible. |
| `SLACKBOT_SCHEDULE_MESSAGE` | Schedule message | Schedules a message to a Slack channel, DM, or private group for a future time (`post_at`), requiring `text`, `blocks`, or `attachments` for content; scheduling is limited to 120 days in advance. |
| `SLACKBOT_SEARCH_ALL` | Search all content | Tool to search all messages and files. Use when you need unified content search across channels and files in one call. Results are scoped to content visible to the authenticated token; missing hits in private or restricted channels reflect permission/membership gaps. Response separates messages and files into distinct sections — explicitly read the files section for document results. Results are index-based and may lag several minutes behind real-time; use SLACK_FETCH_CONVERSATION_HISTORY for near-real-time per-channel coverage. Paginated searches exceeding ~1 req/sec may return HTTP 429 too_many_requests; honor the Retry-After header and resume from the last page. |
| `SLACKBOT_SEARCH_MESSAGES` | Search messages | Workspace‑wide Slack message search with date ranges and filters. Use `query` modifiers (e.g., in:#channel, from:@user, before/after:YYYY-MM-DD), sorting (score/timestamp), and pagination. |
| `SLACKBOT_SEND_EPHEMERAL_MESSAGE` | Send ephemeral message | Sends an ephemeral message visible only to the specified `user` in a channel; other channel members cannot see it. Both the bot and the target user must be members of the specified channel. |
| `SLACKBOT_SEND_ME_MESSAGE` | Share a me message in a channel | Sends a 'me message' (e.g., '/me is typing') to a Slack channel, where it's displayed as a third-person user action; messages are plain text and the channel must exist and be accessible. |
| `SLACKBOT_SEND_MESSAGE` | Send message | Posts a message to a Slack channel, DM, or private group; requires at least one content field (`markdown_text`, `text`, `blocks`, or `attachments`) — omitting all causes a `no_text` error. Fails with `not_in_channel`, `channel_not_found`, or `channel_is_archived` if the bot lacks access. Body limit ~4000 characters. Rate-limited at ~1 req/sec (HTTP 429, honor `Retry-After`). Not idempotent — duplicate calls post duplicate messages. |
| `SLACKBOT_SET_CONVERSATION_PURPOSE` | Set a conversation's purpose | Sets the purpose (a short description of its topic/goal, displayed in the header) for a Slack conversation; the calling user must be a member. |
| `SLACKBOT_SET_READ_CURSOR_IN_A_CONVERSATION` | Set conversation read cursor | Marks a message, specified by its timestamp (`ts`), as the most recently read for the authenticated user in the given `channel`, provided the user is a member of the channel and the message exists within it. |
| `SLACKBOT_SET_THE_TOPIC_OF_A_CONVERSATION` | Set conversation topic | Sets or updates the topic for a specified Slack conversation. |
| `SLACKBOT_SET_USER_PRESENCE` | Set user presence | Manually sets a user's Slack presence, overriding automatic detection; this setting persists across connections but can be overridden by user actions or Slack's auto-away (e.g., after 10 mins of inactivity). |
| `SLACKBOT_SHARE_REMOTE_FILE` | Share a remote file in channels | Shares a remote file, which must already be registered with Slack, into specified Slack channels or direct message conversations. |
| `SLACKBOT_START_CALL` | Start call | Registers a new call in Slack using `calls.add` for third-party call integration; `created_by` is required if not using a user-specific token. |
| `SLACKBOT_UNARCHIVE_CHANNEL` | Unarchive channel | Reverses conversation archival. |
| `SLACKBOT_UNPIN_ITEM` | Unpin message from channel | Unpins a message, identified by its timestamp, from a specified channel if the message is currently pinned there; this operation is destructive. |
| `SLACKBOT_UPDATE_CALL_INFO` | Update call information | Updates the title, join URL, or desktop app join URL for an existing Slack call identified by its ID. |
| `SLACKBOT_UPDATE_REMOTE_FILE` | Update an existing remote file | Updates metadata or content details for an existing remote file in Slack; this action cannot upload new files or change the fundamental file type. |
| `SLACKBOT_UPDATES_A_MESSAGE` | Update a Slack message | Updates a Slack message, identified by `channel` ID and `ts` timestamp, by modifying its `text`, `attachments`, or `blocks`; provide at least one content field, noting `attachments`/`blocks` are replaced if included (`[]` clears them). |
| `SLACKBOT_UPDATE_USER_GROUP` | Update Slack user group | Updates an existing Slack User Group, which must be specified by an existing `usergroup` ID, with new optional details such as its name, description, handle, or default channels. |
| `SLACKBOT_UPDATE_USER_GROUP_MEMBERS` | Update user group members | Replaces all members of an existing Slack User Group with a new list of valid user IDs. |
| `SLACKBOT_UPLOAD_OR_CREATE_A_FILE_IN_SLACK` | Upload or create a file in Slack | Upload files, images, screenshots, documents, or any media to Slack channels or threads. Supports all file types including images (PNG, JPG, JPEG, GIF), documents (PDF, DOCX, TXT), code files, and more. Can share files publicly in channels or as thread replies with optional comments. Large files may fail with `upload_too_large`; use SLACK_ADD_A_REMOTE_FILE_FROM_A_SERVICE for large uploads. If the API returns `ok=false` with `method_deprecated`, fall back to SLACK_ADD_A_REMOTE_FILE_FROM_A_SERVICE or SLACK_SEND_MESSAGE with a URL. |

## Supported Triggers

| Trigger slug | Name | Description |
