Slackbot integration

Add call participants

Registers new participants added to a Slack call.

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.

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.

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.

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.

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').

Create Slack Canvas

Creates a new Slack Canvas with the specified title and optional content.

Create channel

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 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-trackin…

Create Slack List item

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 `paren…

Create a Slack user group

Creates a new User Group (often referred to as a subteam) in a Slack workspace.

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.
