# Single-Use or Time-Based Private Links

> Generate unique, restricted Cal ID booking URLs that expire after use or on a set date so you can share invites without exposing your public profile.

Share a booking invite without revealing your public profile. In **Cal ID**, the **Private Links** feature generates unique, restricted URLs that can expire after a single use or on a set date, giving your scheduling an added layer of security and exclusivity.

## Using private links for maximum privacy

Standard event types have public URLs tied to your username. Private Links let you invite attendees without sharing your direct booking page path.

## Why use private links?

* **Protect your username:** Attendees never see your main **Cal ID** username, which otherwise leads directly to all of your public booking options.
* **Single-use security:** Generate a link that regenerates or expires after each use, so an attendee cannot reuse the same URL to book your time repeatedly.
* **Control distribution:** Prevent your link from being shared around unintentionally, helping you manage incoming booking requests and keep a clean schedule.

## How to set it up

<Steps>
  <Step title="Navigate to Advanced">
    Go to **Event Types**, select your event, and click the **Advanced** tab.
  </Step>

  <Step title="Enable Private Links">
    Toggle the **Private Links** switch to **ON**.

        </Frame>
      </Tab>

      <Tab title="Time-based">
        Choose **Time-based expiration** if the link should only be active until a specific date.

        </Frame>
      </Tab>
    </Tabs>
  </Step>

  <Step title="Copy and share">
    Use the **Copy** icon to grab the unique URL and share it with your attendee.
  </Step>

  <Step title="Save">
    Click the **Save** button at the top right to confirm your settings.
  </Step>
</Steps>

## How it works for the attendee

* The attendee sees a clean booking page that lets them pick a time for that specific event.
* They do not see your public profile or other event types you may have.
* Once they complete the booking (if set to 1 use), the link immediately becomes invalid for any future attempts.

<Info>
  Private Links restrict access to a single event type. To keep an entire event hidden from your public profile, pair this with [secret events](/docs/event-types/basics/secret-events).
