# Configure Invitation URLs to Open on External Websites

Admins can add a URL prefix to an invitation URL to directly open the invitation on an external website.

1.  Set up your website in the Invitation URL Prefix flow attribute.

    For more information, see [Flow Screen Component: Select Service Appointment Time](https://help.salesforce.com/s/articleView?id=platform.ls_flowscreencmp_select_srvc_appt_time.htm&type=5).

2.  Prefix the invitation URL with your website's domain address in the `https://YourSiteDomain/SiteURL` format.


After you prefix the invitation URL in the flow, activate the flow and generate the appointment invitation URL.
