Can I sync individual properties in a one-way sync?

Yes, 2sync supports a granular sync direction by field.

You can set up the sync in two ways: a one-way sync, like from Notion to Google Calendar, which only transfers information in one direction, or a two-way sync, where changes in either tool are reflected in the other. This means any updates or new events you make will automatically appear in both apps.

If you set up a two-way synchronization, you can choose which fields are synced in only one direction. You do this in the Field Mapping section by looking at the arrows next to each field.

Example

In the example below, we set up a two-way sync between Google Calendar and Notion. However, only the Date field updates from Google Calendar to Notion, not vice versa.
