Google Calendar Overview#

The Google Calendar API lets you dip into the powerhouse of scheduling, allowing for the reading, creation, and manipulation of events and calendars directly from your applications. Through Pipedream, you can seamlessly integrate Google Calendar into a myriad of workflows, automating event management, syncing with other services, setting up custom reminders, or even collating data for reporting. The key here is to streamline your calendar-related processes, ensuring that your time management is as efficient and automated as possible.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Google Calendar	`googleCalendar`	`app`	This component uses the Google Calendar app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Calendars	`calendarIds`	`string[]`	Select a value from the drop down menu.
Emit only for new events	`newOnly`	`boolean`	Emit new events only, and not updates to existing events (defaults to `false`)
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
Push notification renewal schedule	`timer`	`$.interface.timer`	The Google Calendar API requires occasional renewal of push notification subscriptions. This runs in the background, so you should not need to modify this schedule.

Trigger Authentication#

Google Calendar uses OAuth authentication. When you connect your Google Calendar account, Pipedream will open a popup window where you can sign into Google Calendar and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Google Calendar API.

Pipedream requests the following authorization scopes when you connect your account:

https://www.googleapis.com/auth/calendar.eventshttps://www.googleapis.com/auth/calendar.readonlyhttps://www.googleapis.com/auth/calendar.settings.readonlyemailprofile

About Google Calendar#

With Google Calendar, you can quickly schedule meetings and events and get reminders about upcoming activities, so you always know what’s next.
