Google Calender

Hi, I’m trying to trigger an action based on my google calender.

I want the action to trigger 30 min before an events starts
But I can only choose the options to start by date or creation.

How do I do this ?


I want to create a simple booking with the use of google calender
When booking is made nothing should trigger but when its 30 min to the events start the trigger should be sent.

Perhaps you can set email reminders 30 minutes before each event, and use that as a trigger using Custom Mailhooks?
