Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Slackbot gives agents workspace-wide read access to a Slack workspace on behalf of the installing user - search messages and files, browse channel and thread history, and look up users and channels - while continuing to post and react as the bot. Includes direct messages and user email addresses so agents can search across DMs and resolve users by email.
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels, including thread replies.
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
DEPRECATED: use `SLACK_CHANNEL_MESSAGE_RECEIVED` with `is_bot_message=true` instead. Triggered when a new bot message is posted to a Slack channel.
Triggered when a new channel is created in Slack.
DEPRECATED: use `SLACK_CHANNEL_MESSAGE_RECEIVED` instead. Triggered when a new message is posted to a Slack channel.
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
DEPRECATED: use `SLACK_MESSAGE_REACTION_REMOVED` instead. Triggered when a reaction is removed from a message.
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.
Registers new participants added to a Slack call.
Adds a link bookmark to a Slack channel and returns the created bookmark. Requires the `bookmarks:write` scope (not granted by default).
Adds a specified emoji reaction to a Slack message identified by channel and timestamp. An already-existing reaction is reported as success.
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.
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.
Finalize uploaded file IDs once and optionally share the files.
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').
Creates a new User Group (often referred to as a subteam) in a Slack workspace.
Initiates a public or private channel-based conversation in a Slack workspace. Immediately creates the channel; invoke only after explicit user confirmation.
Creates a new Slack Canvas with the specified title and optional content.
Creates a new Slack List via `slackLists.create`. Provide a `name` and, optionally, a `description_blocks` description and a `schema` of typed columns. You can instead copy an existing List's structure with `copy_from_list_id` (and its rows via `include_copied_list_records`), or enable task-tracking columns with `todo_mode`. Returns the new List's `list_id`. Requires a user token with the `lists:write` scope.
Creates a new item (row) in a Slack List via `slackLists.items.create`. Set initial cell values with `initial_fields`; text columns require Block Kit `rich_text` (a plain string is wrapped automatically). Optionally duplicate an existing row with `duplicated_item_id` or create a subtask with `parent_item_id`. Requires a user token with the `lists:write` scope.
Customizes URL unfurls in a posted Slack message or message composer using custom preview content or Work Object metadata. It can also provide authentication prompts for unfurling.
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.
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.
Deletes an existing Slack reminder, typically when it is no longer relevant or a task is completed; this operation is irreversible.
Deletes a specific comment from a file in Slack; this action is irreversible.
Deletes several items (rows) from a Slack List in one call via `slackLists.items.deleteMultiple`. This operation is ALL-OR-NOTHING: Slack returns a single `{"ok": true}` on success or `{"ok": false, "error": ...}` on failure, with NO per-item result array, so partial state cannot be reported. On failure, treat the whole batch as not deleted and retry the entire batch. Requires a user token with the `lists:write` scope.
Deletes a pending, unsent scheduled message from the specified Slack channel, identified by its `scheduled_message_id`.
Deletes a Slack Canvas permanently and irreversibly; always confirm with the user before calling. For skill canvases, Slack may return success without deleting the canvas and indicate that the Skills API is required.
Revokes sharing access on a Slack List via `slackLists.access.delete`. Provide the `list_id` and EXACTLY ONE of `channel_ids` or `user_ids` (they are mutually exclusive) to remove access for those channels or users. Requires a user token with the `lists:write` scope.
Deletes an item (row) from a Slack List via `slackLists.items.delete`. Identify the List with `list_id` and the row to remove with `id`. Deletion is permanent and cannot be undone. Requires a user token with the `lists:write` scope.
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.
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.
Edits a Slack Canvas with granular control over content placement. Supports replace, insert (before/after/start/end) operations for flexible content management.
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.
Ends an ongoing Slack call, identified by its ID (obtained from `calls.add`), optionally specifying the call's duration.
Fetches information for a specified, existing Slack bot user; will not work for regular user accounts or other integration types.
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
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.
Fetches comprehensive metadata about the current Slack team, or a specified team if the provided ID is accessible.
Finds Slack channels and conversations visible to the authenticated user by name, topic or purpose, with partial or exact matching. Searches one page at a time; results depend on conversation type, membership, archive settings and access, with a cursor to continue.
Find Slack users by ID, email, name, display name, or other text. General searches filter one page per call and return a cursor; direct ID and exact-email lookup failures may return empty results with a diagnostic message.
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.
Retrieves detailed information for an existing Slack reminder specified by its ID; this is a read-only operation.
Retrieve information about a remote file added to Slack via the files.remote API. Does not work for standard Slack-hosted file uploads.
Retrieves file metadata for a Slack Canvas by its ID. This action is deprecated and does not retrieve canvas document content.
Fetches a single item (row) from a Slack List via `slackLists.items.info`. Returns the row's `column_id`-keyed typed values along with metadata about the parent List. Set `include_is_subscribed` to also report whether the calling user is subscribed to the row. Requires a user token with the `lists:read` scope.
Retrieves current Do Not Disturb status for specified Slack users, up to 50 per request.
Retrieves unread direct messages from a specified user in the authenticated user's DM conversation, checking message history after the last-read timestamp. Opens or resumes the DM and returns matching messages oldest first, with a limit of 25 by default and up to 999.
Invites users to an existing Slack channel using their Slack user IDs. Slack API failures raise an error, which may include per-user invitation failures.
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.
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.
Lists conversations available to the authenticated user, with filters for conversation type and archived status. Results are paginated; the created field is a Unix timestamp.
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.
Retrieves a list of all user IDs within a specified Slack user group, with an option to include users from disabled groups.
Lists a page of Slack workspaces authorized for the connection that also appear in the target user's visible Enterprise Grid memberships. Returns workspace IDs and names with a cursor for further pages; missing membership data yields an empty result.
Lists the bookmarks saved in a Slack channel. Requires the `bookmarks:read` scope (not granted by default).
Lists a page of Slack conversations for a specified user or the authenticated user, with filters for conversation type and archived status. Results contain conversation objects with IDs and may include channel names; access and selected types affect which conversations appear.
Retrieves all messages and files pinned to a specified channel; the caller must have access to this channel.
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.
Retrieve information about a team's remote files.
Lists accessible Slack Canvases using page-based pagination and optional channel, user and timestamp filters. This deprecated action's user filter may include canvases accessible to the user, and timestamp filters may not be reliable for canvases.
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.
Lists the rows (items) in a Slack List via `slackLists.items.list`. Each row exposes `column_id`-keyed typed values (e.g. `rich_text`, `select`, `user`, `date`, `number`); the legacy `key`/`value` fields are deprecated. Results are cursor-paginated—you must paginate using `response_metadata.next_cursor` until it is empty, or rows are silently truncated to the first page. Set `archived=true` to return archived rows instead of active ones. Requires a user token with the `lists:read` scope.
Retrieves all custom emojis for the Slack workspace (image URLs or aliases), not standard Unicode emojis; does not include usage statistics or creation dates.
Lists a page of unread main-timeline messages in a Slack channel for the authenticated user, using the last read position or zero if unavailable. Use the returned cursor to request another page; threaded replies are not included.
Lists user groups in a Slack workspace, including user-created and default groups, with options to include disabled groups, user IDs, and member counts.
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.
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.
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.
Tool to mark a user as active in Slack. Note: This endpoint is deprecated and non-functional - it exists for backwards compatibility but does not perform any action.
Opens or resumes a Slack direct message or multi-person direct message using user IDs or an existing conversation ID. Returns the conversation ID and may indicate that the conversation is already open.
Pins a message to a specified Slack channel; the message must not already be pinned.
Registers participants removed from a Slack call.
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.
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.
Removes a specified user from a Slack conversation (channel); the caller must have permissions to remove users and cannot remove themselves using this action.
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.
Reserve a temporary Slack upload URL without uploading bytes. Upload the exact bytes to the returned URL, then call Slack's files.completeUploadExternal method; Slack aborts reservations that are not completed.
Retrieves a point-in-time snapshot of a specific Slack call's information.
Retrieves metadata for a Slack conversation by ID, including name, purpose and creation date, with options for member count and locale. Returned fields vary by conversation type and access.
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.
Retrieves detailed metadata and paginated comments for a specific Slack file ID; does not download file content.
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.
Retrieves all profile field definitions for a Slack team, optionally filtered by visibility, to understand the team's profile structure.
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.
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.
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.
Revokes public or external sharing access for a Slack file by its file ID.
Schedules a message to a Slack channel, DM, or private group for a future time, up to 120 days in advance. Content can be supplied as Markdown, text, blocks, or attachments; Markdown is converted to blocks.
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.
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.
Search files visible to the connected Slack user by text and modifiers.
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.
Posts a message to a Slack channel, DM, or private group. Provide exactly one visible content mode: `markdown_text` for normal Markdown content, or `blocks` for raw Slack Block Kit layouts. Use `fallback_text` only with `blocks`; it maps to Slack's top-level `text` fallback. Fails with `not_in_channel`, `channel_not_found`, or `channel_is_archived` if the bot lacks access. Rate-limited at ~1 req/sec (HTTP 429, honor `Retry-After`). Not idempotent — duplicate calls post duplicate messages.
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.
Change access for channels or users a Slack canvas is already shared with. Share the canvas link in each target channel or directly with each target user before calling this action; Slack rejects targets that do not already have the link. Requires the `canvases:write` scope (not granted by default).
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.
Sets or updates the topic for a specified Slack conversation.
Grants or sets sharing access on a Slack List via `slackLists.access.set`. Grant `read`, `write`, or `owner` access to either channels (`channel_ids`) or users (`user_ids`) — exactly one of the two is required. The `owner` level is user-only and subject to additional server-side rules. Requires a user token with the `lists:write` scope.
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).
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.
Shares a remote file, which must already be registered with Slack, into specified Slack channels or direct message conversations.
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.
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.
Checks authentication and tells you who you are. Use to verify Slack API authentication is functional and to retrieve identity information about the authenticated user or bot.
Reverses conversation archival.
Unpins a message, identified by its timestamp, from a specified channel if the message is currently pinned there; this operation is destructive.
Updates a Slack message by timestamp. Provide exactly one visible content mode: `markdown_text` for normal Markdown content, or `blocks` for raw Slack Block Kit layouts. Use `fallback_text` only with `blocks`; it maps to Slack's top-level `text` fallback.
Updates metadata or content details for an existing remote file in Slack; this action cannot upload new files or change the fundamental file type.
Updates the title, join URL, or desktop app join URL for an existing Slack call identified by its ID.
Updates a Slack List's metadata via `slackLists.update`. Only the List's `name`, `description_blocks`, and `todo_mode` are editable here. The List to update is identified by its `id` (not `list_id`). Descriptions are rich text — a plain string is wrapped into a `rich_text` block automatically. Requires a user token with the `lists:write` scope.
Updates one or more cells in an EXISTING Slack List row via `slackLists.items.update`. Each cell is identified by `row_id` (an existing row ID matching `^Rec[A-Z0-9]{8,}$`) and `column_id` and carries a typed value; text columns require Block Kit `rich_text` (a plain string is wrapped automatically), and `select` takes the column's choice values (e.g. `["todo"]`). Use it to UPDATE existing rows; the live API rejects `row_id_to_create` inside a cell (despite Slack's inline example), so to ADD a row use `create_slack_list_item`. Requires a user token with the `lists:write` scope.
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.
Replaces the members of an existing Slack User Group with a complete list of user IDs. The list cannot be empty; guests and bot users cannot be added.
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.
