Version:0.0.9
Key:google_drive-new-or-modified-comments

Code

// This source processes changes to any files in a user's Google Drive,
// implementing strategy enumerated in the Push Notifications API docs:
// https://developers.google.com/drive/api/v3/push and here:
// https://developers.google.com/drive/api/v3/manage-changes
//
// This source has two interfaces:
//
// 1) The HTTP requests tied to changes in the user's Google Drive
// 2) A timer that runs on regular intervals, renewing the notification channel as needed

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.
LabelPropTypeDescription
Google DrivegoogleDriveappThis component uses the Google Drive app.

Watch for changes to file properties
in addition to changes to content. Defaults to false, watching for only changes to content.

Push notification renewal scheduletimer$.interface.timer

The Google Drive API requires occasional renewal of push notification subscriptions. This runs in the background, so you should not need to modify this schedule.

Authentication

Google Drive uses OAuth authentication. When you connect your Google Drive account, Pipedream will open a popup window where you can sign into Google Drive 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 Drive API.

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