Inputs

​
🛠️ Required Fields

There are no additional fields to configure — once your Slack account is connected and the apphook is enabled, this node is ready to fire on every new member event.

​
🎯 Optional Fields

No optional fields for this trigger.

​
Output

When a new member joins your workspace, this node emits a user object containing fields like:
  • id — Slack user ID
  • name — display name
  • email — user email address
  • team_id — workspace identifier
  • event_ts — timestamp of the join event
These outputs can feed into downstream nodes for CRM updates, notifications, or data enrichment.

Event payload fields are auto-detected. If multiple payload properties share a name, the node appends an index (email_1, email_2).

​
How It Works

  1. Connects to your Slack workspace via the apphook.
  2. Listens for the team_join event whenever a member is added.
  3. Captures structured user data (ID, name, email, team) in real time.
  4. Emits the data to trigger downstream actions like CRM syncs, welcome bots, or reporting dashboards.

🚀 Example Use Cases & Prompts

Use CaseSetup or Prompt Example

​
✨ Pro Tips

  • Confirm your Slack apphook has permission to read user events before enabling the node.
  • Use @ColumnName or the Insert Input button to map user fields into downstream messages or records.
  • Filter by user type (bot vs. human) in downstream steps to avoid noisy events.

​
⚠️ Important Considerations

  • Your Slack workspace must allow custom apphooks; check with your admin if events aren’t showing.
  • Excessive join events from large orgs may impact credit usage; consider filtering by user roles.
  • Ensure the bot is invited to any shared channels if you plan to post welcome messages there.
