Slack ACTION

Find User by ID

Find a user by their ID — including a specific user you already have the Slack ID for, whether or not it's your own. Returns user profile information including name, email (requires users:read.email scope), timezone, and status. If you only have an email address, use Find User by Email instead.

IMPLEMENTATION

Call this tool

Connect a user's Slack account once, then configure and run Find User by ID 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-find-user-by-id",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    slack_v2: { authProvisionId: "apn_xxxxxxx" },
    user: "User",
    includeLocale: true,
  },
})

console.log(result)
