Getting Started

This integration creates a workflow with a Google Drive trigger and HTTP / Webhook action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Select this integration
  2. Configure the New or Modified Comments trigger
    1. Connect your Google Drive account
    2. Select a Drive
    3. Optional- Configure Watch for changes to file properties
    4. Configure Push notification renewal schedule
  3. Configure the Send POST Request action
    1. Connect your HTTP / Webhook account
    2. Configure HTTP Request Configuration
  4. Deploy the workflow
  5. Send a test event to validate your setup
  6. Turn on the trigger

Details

This integration uses pre-built, open source components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger

Description:Emits a new event any time a file comment is added, modified, or deleted in your linked Google Drive
Version:0.0.9
Key:google_drive-new-or-modified-comments

Trigger 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

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.
LabelPropTypeDescription
Google DrivegoogleDriveappThis component uses the Google Drive app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between component invocations.
N/Ahttp$.interface.httpThis 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.

Watch for changes to file propertieswatchForPropertiesChangesboolean

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.

Trigger 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:
