How to create a multi-way calendar sync in OneCal
A multi-way calendar sync copies events between two or more calendars, in every direction, within a single calendar sync.
A multi-way calendar sync uses one sync configuration for all the calendars involved, so you cannot customize settings such as event titles or colors per calendar. To use different settings for each calendar, create several one-way calendar syncs instead. See the How to create a one-way calendar sync in OneCal guide for more information.
This guide will walk you through the process of creating a multi-way calendar sync in OneCal.
Prerequisites
Before starting make sure you have the following:
- A OneCal account with either an active Free Trial or any paid plan.
- At least 2 calendars connected to your OneCal account.
- You are already logged in to your OneCal account.
