Can i set condions on google calender?

can I set the condition to create the event? For example IF certain field IS EQUAL TO certain VALUE, THEN create event in Google Calendar.

I am afraid that you cannot set conditions on the Google Calendar integration. Every time when the user submits the form, an individual event will be added to the appropriate Google Calendar. We cannot restrict this using conditions.

However, no event will be created if a user leaves the date field empty or enters incomplete times or dates. So, you can take advantage of this to achieve your requirement.

IF certain field IS EQUAL TO certain VALUE, THEN create event in Google Calendar.

So, when the field is not equal to the certain value which means when the condition that you set doesn't satisfy then you can hide the Date field so the user cannot fill the date field and as the date field is empty no event will be created.
