You can quickly add co-hosts to your Booking Calendar link without altering your default settings.

This method is ideal when you need to include additional co-hosts to a meeting instantly.

How Availability Works

The availability for the added co-hosts is determined by two factors:

1. From where the Booking Calendar retrieves Availability:

   • The hosts’ profile settings.

   • Within the specific Booking Calendar.

2. Any busy time marked in the co-host’s connected calendar.

Example: This feature is useful if, for instance, a hiring manager needs a senior team member to join a technical interview. It allows the manager to instantly create a once-off panel booking link. This link includes both the host and the required co-host, without the overhead of setting up a separate Booking Calendar.

Prerequisite

Before you begin, ensure that the co-host's email address belongs to a user with an assigned seat/ license on the same OnceHub account.
