Online appointment scheduling with Zoho Calendar
Share a Kalendarius booking link and let your Zoho Calendar decide when you are free. Kalendarius checks the Zoho calendars you choose for busy times and puts each confirmed appointment into the calendar you pick.
Kalendarius checks every Zoho calendar you tick for busy times and writes each booking into one destination calendar. The titles and descriptions of your other events are not stored. Zoho Calendar works on every plan: start free on the Personale plan and connect it from the dashboard.
What the connection asks Zoho for
When you connect, Zoho asks you to approve three permissions: ZohoCalendar.calendar.READ to list your calendars, ZohoCalendar.freebusy.READ to see when you are busy, and ZohoCalendar.event.ALL to create, move and delete the events for your bookings. There is no access to Zoho Mail or other Zoho apps.
For the calendars that block your availability, we only look at busy times. The titles and descriptions of those events are not stored.
Connect Zoho Calendar step by step
Sign in to Kalendarius, open Calendars in the dashboard and choose Connect on the Zoho Calendar card. Approve the permissions on Zoho's consent screen and you come back with the connection active.
Under "Calendars that block availability", tick every Zoho calendar whose events should keep you from being booked: your work calendar, a shared team calendar, a personal one. Until you change it, the selection follows the calendars included in your Zoho Free/Busy settings.
Under "Booking destination calendar", pick the one calendar where new bookings go. It has to be a calendar you can write to. Then choose Save calendar settings.
What happens when someone books
A guest picks a slot on your booking page, and a few moments later the event appears in your destination calendar. If the guest reschedules, the Zoho event moves with the booking. If the booking is cancelled, the event is deleted.
For video calls, set the event type's location to Zoho Meeting, explained on Zoho Meeting scheduling.
Zoho next to Google and Microsoft
You can connect one Zoho, one Google and one Microsoft 365 or Outlook account at the same time, and busy times in any of them block your slots. Zoho is the only connection where you pick several calendars. Zoho Calendar works on every plan, including Personale, which is free for one organizer, one event type and 15 bookings a month.
Zoho Bookings or a Kalendarius booking link
Zoho Bookings is Zoho's own appointment scheduling app. If your team already uses it, keeping scheduling inside Zoho is the simpler setup.
A Kalendarius booking link is the other option. It checks several Zoho calendars for conflicts, can add a Zoho Meeting link to each booking, and lets you sign in with your Zoho account. The application and database run on Hetzner servers in Germany. You pay per organizer, the person who creates booking links, and colleagues who only connect a calendar don't pay.
Frequently asked questions
Can I choose which Zoho calendars block bookings?
Yes. Tick them under "Calendars that block availability" in the Zoho Calendar settings, and pick one destination calendar for new bookings.
What if none of my Zoho calendars can be written to?
The connection needs at least one calendar you can write to, because that is where bookings go. Get write access to a calendar in Zoho, then reconnect.
