IMPLEMENTATION

Deploy this event source

Connect the user's Slack account, configure the source, and choose the webhook where your backend receives events.

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 deployed = await pd.triggers.deploy({
  id: "slack_v2-new-reaction-added",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    slack_v2: { authProvisionId: "apn_xxxxxxx" },
    conversations: ["Channels"],
    ignoreBot: true,
  },
  webhookUrl: "https://example.com/webhooks/slack-v2",
})

console.log(deployed.id)

MCP exposes on-demand actions. Event sources are deployed through the Connect SDK or API because they continue listening after the initial request.
