Cal ID FAQ's

Quick answers to the questions Cal ID users ask most.

Yes. In Profile Settings, add multiple emails and set one as your Primary address for notifications.

Yes. Your booking link is based on your username (cal.id/username), so changing your username will make your old booking links invalid. You’ll need to share your new booking link.

If you’ve embedded your booking page on your website, the existing embed also be affected, so make sure to update the embed with your new username/link.

Yes. Go to Apps › Calendars › Install to connect multiple Google accounts and check them all for conflicts.

The title is the event name people see (e.g., "Intro Call"). The slug is the web address (e.g., /intro). Changing the slug breaks old links, while changing the title doesn't.

Zoom doesn't appear directly in the location dropdown for team events. Instead, choose Organizer's default app, and make sure every host has Zoom set as their default at app.cal.id/apps/installed/conferencing.

Install Zoom from the App Store, then select Zoom in your event type's Location dropdown.

The event is a Collective Team Event, and one or more assigned hosts do not have a paid license.

License the host, or remove them from the event.

The Startup plan includes up to 10 SMS/WhatsApp messages per month. If you have already used your monthly limit, additional messages will not be sent.

If you need to send more messages, you’ll need to upgrade to the Business plan.

If everything is configured correctly, please share the details of the issue with our support team so we can investigate further.
