Integrating and two-way synchronization with Google Calendar

Hey guys

Here is what I am wondering:
I have a webpage involving pets.
On the intake form for new pet clients I have a date picker for 4 different vaccination expiries (linked to a database collection). I would like to be able to sync those expiry dates with my google calendar just from the user input and database. Is there a function like that? Or anything set up so that I don’t have to input the data separately into google calendar and sync it into my site?

The Google Sheets NPM example demonstrates how to interface with the Google API. This will give you a good start.
