Hence, we've been tightly working to provide a two-way sync between Calendly and Zoho Calendar. But it's being delayed owing to the technical priorities on the Calendly end for which we're in continuous talks to make them integrate Zoho Calendar as mentioned in the community thread given above.
In the meanwhile to help Zoho Calendar users who have been using Calendly, we've come up with a One-way sync between Calendly and Zoho Calendar. This will help users to view the Calendly events in Zoho Calendar.
As part of this initiative we're providing a Beta access to the customers who wanted to have the One-way sync between Calendly and Zoho Calendar. If you want the feature to be enabled for your organization/ account please send an email to support(at)zohocalendar(dot)com, with the subject "Calendly One-way sync - Beta access request".
Our support team will help you with the Beta access to the One-way sync of Calendly with Zoho Calendar.
