Slack ACTION

Leave Channel

Remove the authenticated user from a public or private channel. Leaving a channel the user is not a member of is a no-op, reported as not_in_channel: true. To leave several channels (e.g. every channel matching a pattern), use List Channels with memberOnly: true to find them, then call this action once per channel ID. See the documentation

IMPLEMENTATION

Call this tool

Connect a user's Slack account once, then configure and run Leave Channel from your backend or agent.

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "slack_v2-leave-channel",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    slack_v2: { authProvisionId: "apn_xxxxxxx" },
    conversation: "Channel",
  },
})

console.log(result)

SCHEMA

Inputs

Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.

Leave Channel inputs
Property Type Description
conversation Channel string
Prefer a channel ID (e.g. C1234567890) - use List Channels to look it up; it resolves instantly. A channel name (e.g. general or #general) is also accepted, but resolving it scans up to 5 pages (~5,000 channels) of the workspace's channel list, which can be slow - and a valid channel beyond that bound will not be found. Direct messages and the workspace's general channel can't be left.
Required

REFERENCE

Tool details

Behavior hints are published with the component in the Pipedream registry and surface as MCP tool annotations, so an agent can reason about a tool before it calls it.
