# How to Set Up Requires Confirmation for a Booking?

**Requires confirmation** is a gatekeeper for your appointments — bookings must be approved before they're finalized, added to your calendar, or confirmed to the guest.

| Configuration options

* **Always:** every booking needs your approval.
* **When booked with less than [X] notice:** allow instant bookings far ahead, but require approval for last-minute requests.
* **Unconfirmed bookings still block calendar slots:** hold the requested slot as busy while you decide.
* **Only require confirmation for free email providers:** auto-approve work domains, but vet guests using Gmail, Outlook, etc.

| Set it up

1. Open **Event Types** and click the event.
2. Toggle **Requires confirmation** **ON**.
3. Choose **Always** or the notice threshold, and tick the slot-blocking / free-email options as needed.
4. Click **Save**.

| How it works

The guest submits their request and sees a **pending approval** message — no confirmation email or meeting link is generated until you approve.

| Approve a booking

* **Email:** approve or reject from the notification.

* **Dashboard:** open the **Bookings** tab to see pending requests.

On **Confirm**, the guest gets their confirmation email and the event syncs to your calendar.

> **Multiple requests for the same slot:** you can accept only one. The rest stay **unconfirmed**. To accept a different one, first cancel the previously accepted booking for that slot, then approve another.
