Slack (v2) connector

The Slack (v2) connector enables workflow-driven Slack automation: search Slack messages, list conversations the token can access, resolve channel IDs from names, send messages, create channels, and invite users to Slack channels using the Slack Web API. It authenticates using OAuth Authorization Code (Slack OAuth v2).

You can create connectors in Stack Management > Connectors.

Slack (v2) connectors use OAuth Authorization Code authentication. When creating the connector, you will be prompted to authorize access to your Slack workspace. No additional configuration properties are required beyond the OAuth credentials.

You can test connectors when you create or edit the connector in Kibana. The test verifies connectivity by calling Slack auth.test.

The Slack (v2) connector has the following actions:

Search messages

Search for messages in Slack.

• query (required): Slack search query string.
• inChannel (optional): Adds in:<channel_name> to the query.
• fromUser (optional): Adds from:<@UserID> or from:username to the query.
• after (optional): Adds after:<date> to the query (for example, 2026-02-10).
• before (optional): Adds before:<date> to the query (for example, 2026-02-10).
• sort (optional): Sort order, score or timestamp.
• sortDir (optional): Sort direction, asc or desc.
• count (optional): Results to return (1 to 20). Slack returns up to 20 results per page.

• includeContextMessages (optional): Include contextual messages. Defaults to true.
• includeBots (optional): Include bot messages. Defaults to false.
• includeMessageBlocks (optional): Include Block Kit blocks. Defaults to true.
• raw (optional): If true, returns the full raw Slack response (verbose).

List channels

List Slack conversations the token can see (one page per call), using Slack conversations.list. Use this to browse channel IDs or answer which channels exist. When the response includes hasMore: true, call List channels again with nextCursor from the previous response.

• types (optional): Conversation types to include: public_channel, private_channel, im, mpim. Defaults to public_channel only. If you pass an empty array, it defaults to public_channel.
• excludeArchived (optional): Exclude archived conversations. Defaults to true.
• cursor (optional): Pagination cursor from a previous List channels response (nextCursor). Omit for the first page.
• limit (optional): Conversations per page (1 to 1000). Defaults to 1000.
• raw (optional): If true, returns the full raw Slack API response instead of a compact result. Defaults to false.

Resolve channel ID

Resolve a Slack conversation ID (C... for public channels, G... for private channels) from a human channel name (for example, #general).

• name (required): Channel name (with or without #).
• types (optional): Conversation types to search. Defaults to public_channel.
• match (optional): exact (default) or contains.
• excludeArchived (optional): Exclude archived channels. Defaults to true.
• cursor (optional): Pagination cursor to resume a previous scan.
• limit (optional): Channels per page (1 to 1000). Defaults to 1000.
• maxPages (optional): Maximum pages to scan before giving up. Defaults to 10.

Get conversation history

Fetch a page of recent messages from a Slack channel or DM using Slack conversations.history. Returns messages newest-first. When the response includes hasMore: true, call Get conversation history again with nextCursor from the previous response.

• channel (required): Conversation ID (for example, C123... for channels, G... for private channels, D... for DMs).
• oldest (optional): Only messages after this Unix timestamp (string form, for example 1234567890.123456).
• latest (optional): Only messages before this Unix timestamp (string form).
• inclusive (optional): Include messages with the oldest or latest timestamps in results.
• limit (optional): Messages per page (1 to 1000). Defaults to 100.
• cursor (optional): Pagination cursor from a previous response (nextCursor). Omit for the first page.
• raw (optional): If true, returns the full raw Slack response. Defaults to false.

Get conversation info

Look up metadata for a single Slack channel or DM by ID using Slack conversations.info. Returns the channel object (name, privacy, membership, topic, purpose).

• channel (required): Conversation ID.
• includeNumMembers (optional): Set to true to include the member count in the channel object.
• includeLocale (optional): Set to true to include the channel locale.
• raw (optional): If true, returns the full raw Slack response instead of just the channel object. Defaults to false.

Look up user by email

Find a Slack user by email address using Slack users.lookupByEmail. Throws if no user has that email.

• email (required): Email address of the user to look up.
• raw (optional): If true, returns the full raw Slack response instead of just the user object. Defaults to false.

List users

List Slack workspace users (one page per call) using Slack users.list. When the response includes hasMore: true, call List users again with nextCursor from the previous response.

• limit (optional): Users per page (1 to 1000). Defaults to 200.
• cursor (optional): Pagination cursor from a previous response.
• includeLocale (optional): Set to true to include the user locale.
• raw (optional): If true, returns the full raw Slack response.

Who am I

Return the identity the connector is currently authenticated as, using Slack auth.test. Useful before a write action to confirm the workspace/user, or to resolve "me" to a concrete user_id.

• raw (optional): If true, returns the full raw Slack response. Defaults to false.

Get file info

Look up a single Slack file by ID using Slack files.info. Returns the file metadata (name, mimetype, size, URLs, sharing channels).

• file (required): Slack file ID (for example, F0123ABCDE).
• raw (optional): If true, returns the full raw Slack response instead of the file object. Defaults to false.

List files

List Slack files (one page per call) using Slack files.list. Filter by channel, user, time range, or types. Slack files.list is classic-paginated, so this action uses page/pages rather than cursors.

• channel (optional): Restrict results to a single channel/DM ID.
• user (optional): Restrict results to files uploaded by a single user ID.
• tsFrom (optional): Only include files created after this Unix timestamp (string form).
• tsTo (optional): Only include files created before this Unix timestamp (string form).
• types (optional): Comma-separated Slack file type filter (for example, images,pdfs).
• count (optional): Files per page (1 to 200). Defaults to 100.
• page (optional): 1-indexed page number. Defaults to 1. Use nextPage from the previous response to walk pages.
• raw (optional): If true, returns the full raw Slack response.

List user conversations

• user (optional): User ID (for example, U...) whose conversations to list.
• types (optional): Conversation types to list (public_channel, private_channel, im, mpim). Defaults to all four — DMs and private channels are usually the more interesting answer for a per-user query.
• excludeArchived (optional): Exclude archived channels. Defaults to true.
• limit (optional): Channels per page (1 to 1000). Defaults to 1000.
• cursor (optional): Pagination cursor from a previous response.
• raw (optional): If true, returns the full raw Slack response.

Create conversation

Create a new Slack channel (public or private).

• name (required): Channel name. Must contain only lowercase letters, numbers, hyphens, and underscores (80 characters or fewer).
• isPrivate (optional): Whether to create a private channel. Defaults to false.

Invite to conversation

Invite users to a Slack channel.
