The only "trigger" I see in the API is for notifications.
https://developers.google.com/calendar/api/guides/push

Do you think this is something I can use?

Ill get back to you

Yea that's exactly what you need imo
Currently, the Google Calendar API supports notifications for changes to the Acl, CalendarList, Events, and Settings resources.

If your use case is within those notifications^

So I'd need something to receive the push and trigger a revalidation. I think I'd need an API route for that, right?

Yea you set up a route handler in nextjs which takes those post requests which google calender sends

The only thing I'm not sure about is where in the NextJS system this incoming notification go

and you setup that route handler (api endpoint) somewhere within a notification dashboard or whatever on google calender as a setting

Cool

I can do that

This should make it so I don't need to manually add a timer for revalidation right?

withon your route handler in nextjs you can use revalidate

yea it changes your system from "pulling" the data

to google pushing it to you

Any reason I'd want it to stay "pulling"?

so yeah set up a route handler e.g. yourdomain.com/api/googleCalendarupdated which takes a post request.
Setup that `yourdomain.com/api/googleCalendarupdated in the Google Dashboard you basically tell it when to call this url (on what event)
And your routehandler itself so yourdomain.com/api/googleCalendarupdated just revalidates your internal path e.g. your homepage or where ever you need the update to occur

----
If you pull the network every x seconds, you do that 10 times but there is no new data, there might be new data 1 time. So you have some unnecessary network traffic

if it gets pushed you only have network traffic when something actually happend

But other than that its the same thing

Sounds like moving to google pushing is ideal for this situation

So I get changes when they are made and don't check when they are the same

It technically is the better soltuion yes

yes correct

Wooo! Thank you so much

So I've been trying to read the docs and figure this out, but I'm sorta stuck...

In the docs, they say you need to set up a channel for the "webhook," but I'm not entirely sure where I can do that and where I would tell the callback to go to the endpoint I create. Any ideas?

https://developers.google.com/calendar/api/guides/push#overview

I see this example, but I'm not sure where or what to do with it 😦

POST https://www.googleapis.com/calendar/v3/calendars/my_calendar@gmail.com/events/watch
Authorization: Bearer auth_token_for_current_user
Content-Type: application/json

{
  "id": "01234567-89ab-cdef-0123456789ab", // Your channel ID.
  "type": "web_hook",
  "address": "https://mydomain.com/notifications", // Your receiving URL.
  ...
  "token": "target=myApp-myCalendarChannelDest", // (Optional) Your channel token.
  "expiration": 1426325213000 // (Optional) Your requested channel expiration time.
}

Hi can you make another thread? since its already a different question

The example you posted is just the programmatic way of creating a "notification for changes" or webhook in short.

You basically just create a request in your favorite http client e.g. curl, postman, etc. and do a POST to the endpoint https://www.googleapis.com/calendar/v3/calendars/my_calendar@gmail.com/events/watchand a body which reflect the settings for your webhook, e.g. your route handlers URL.

I was talking about a dashboard earlier. Maybe they don't have a UI to do the same thing. But the example shows the "programatic" way.

My apologies! I'll make a new thread for this followup question 👍
