How do I get a Traction Guest API key and where do I find it?

Log in to your Traction Guest account, go to the **Developer Portal** at us.tractionguest.com/dev_portal, and generate a new API key. Copy the key immediately and paste it into the API key field below. This key authenticates all API v3 requests to https://us.tractionguest.com/api/v3.

What's the difference between invites, sign-ins, and registrations?

**Invites** are scheduled visitor appointments created in advance (future visits). **Sign-ins** are actual check-in records when visitors arrive on-site (current/past visits). **Registrations** are pre-registration records awaiting conversion to invites. The workflow is: Registration → Invite → Sign-in (check-in) → Sign-out.

Can I create multiple hosts at once for bulk employee onboarding?

Yes! Use the `create_hosts_batch` tool with an array of host objects. Each host needs firstName, lastName, and email. This is much more efficient than creating hosts one at a time, especially when onboarding new teams or importing from HR systems.

How do I manage group visits like tours and training sessions?

Use `create_group_visit` to schedule a group event with name, date, expected attendees, host, and location. Then use `list_group_visits` to see all upcoming group events. You can update or delete group visits as needed. Each group visit tracks expected vs actual attendance.
