Google Cloud Overview#

The Google Cloud API opens a world of possibilities for enhancing cloud operations and automating tasks. It empowers you to manage, scale, and fine-tune various services within the Google Cloud Platform (GCP) programmatically. With Pipedream, you can harness this power to create intricate workflows, trigger cloud functions based on events from other apps, manage resources, and analyze data, all in a serverless environment. The ability to interconnect GCP services with numerous other apps enriches automation, making it easier to synchronize data, streamline development workflows, and deploy applications efficiently.

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 Cloud	`googleCloud`	`app`	This component uses the Google Cloud app.
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.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Type	`topicType`	`string`	Select a value from the drop down menu:`existingnew`

Trigger Authentication#

Google Cloud uses API keys for authentication. When you connect your Google Cloud account, Pipedream securely stores the keys so you can easily authenticate to Google Cloud APIs in both code and no-code steps.

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.

Action Configuration#

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

Label	Prop	Type	Description
Google Calendar	`googleCalendar`	`app`	This component uses the Google Calendar app.
Calendar ID	`calendarId`	`string`	Select a value from the drop down menu.
iCal UID	`iCalUID`	`string`	Specifies event ID in the iCalendar format to be included in the response. Optional.
Max Attendees	`maxAttendees`	`integer`	The maximum number of attendees to include in the response. If there are more than the specified number of attendees, only the participant is returned. Optional.
Max Results	`maxResults`	`integer`	Maximum number of events returned on one result page. The number of events in the resulting page may be less than this value, or none at all, even if there are more events matching the query. Incomplete pages can be detected by a non-empty nextPageToken field in the response. By default the value is 250 events. The page size can never be larger than 2500 events. Optional.
Order By	`orderBy`	`string`	Select a value from the drop down menu:`{ "label": "startTime", "value": "startTime" }{ "label": "updated", "value": "updated" }`
Private extended property	`privateExtendedProperty`	`string`	Extended properties constraint specified as propertyName=value. Matches only private properties. This parameter might be repeated multiple times to return events that match all given constraints.
Query	`q`	`string`	Free text search terms to find events that match these terms in any field, except for extended properties. Optional.
Shared Extended Property	`sharedExtendedProperty`	`string`	Extended properties constraint specified as propertyName=value. Matches only shared properties. This parameter might be repeated multiple times to return events that match all given constraints.
Show Deleted	`showDeleted`	`boolean`	Whether to include deleted events (with status equals "cancelled") in the result. Cancelled instances of recurring events (but not the underlying recurring event) will still be included if showDeleted and singleEvents are both False. If showDeleted and singleEvents are both True, only single instances of deleted events (but not the underlying recurring events) are returned. Optional. The default is False.
Show Hidden Invitations	`showHiddenInvitations`	`boolean`	Whether to include hidden invitations in the result. Optional. The default is False.
Single Events	`singleEvents`	`boolean`	Whether to expand recurring events into instances and only return single one-off events and instances of recurring events, but not the underlying recurring events themselves. Optional. The default is False.
Max Time	`timeMax`	`string`	Upper bound (exclusive) for an event's time to filter by. Must be an RFC3339 timestamp with mandatory time zone offset, for example, 2011-06-03T10:00:00-07:00, 2011-06-03T10:00:00Z. Milliseconds may be provided but are ignored. Must be greater than Min Time.
Min time	`timeMin`	`string`	Lower bound (exclusive) for an event's time to filter by. Must be an RFC3339 timestamp with mandatory time zone offset, for example, 2011-06-03T10:00:00-07:00, 2011-06-03T10:00:00Z. Milliseconds may be provided but are ignored. Must be smaller than Max Time.
Time Zone	`timeZone`	`string`	Select a value from the drop down menu.
Minimum Updated Time	`updatedMin`	`string`	Lower bound for an event's last modification time (as a RFC3339 timestamp) to filter by. When specified, entries deleted since this time will always be included regardless of showDeleted. Optional. The default is not to filter by last modification time.
Event Types	`eventTypes`	`string[]`	Select a value from the drop down menu:`defaultfocusTimeoutOfOfficeworkingLocation`

Action 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.readonly

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.
