On channel member joined

slack.onChannelMemberJoined emits member_joined_channel events for conversations visible to the installed bot.

automations/welcome-slack-members.automation.ts

import { automation } from "automate.ax"
import { slack } from "automate.ax/slack"

export default automation("Welcome Slack members", () => {
  const membership = slack.onChannelMemberJoined()
  // Use membership.userId to welcome the member in this Slack channel.
})

The result includes userId, conversationId, conversationTypeCode ("C" or "G"), optional inviterId and enterpriseId, the typed original event, and the complete envelope. Slack’s membership event does not distinguish public from private conversations; use slack.getSlackConversation when that distinction matters.
