Google Drive Overview#

The Google Drive API on Pipedream allows you to automate various file management tasks, such as creating, reading, updating, and deleting files within your Google Drive. You can also share files, manage permissions, and monitor changes to files and folders. This opens up possibilities for creating workflows that seamlessly integrate with other apps and services, streamlining document handling, backup processes, and collaborative workflows.

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.

Label	Prop	Type	Description
Google Drive	`googleDrive`	`app`	This component uses the Google Drive app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
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.
Drive	`drive`	`string`	Select a value from the drop down menu.
Push notification renewal schedule	`timer`	`$.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.
File	`fileId`	`string`	Select a value from the drop down menu.

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:

https://www.googleapis.com/auth/drive

About Google Drive#

Google Drive is a file storage and synchronization service which allows you to create and share your work online, and access your documents from anywhere.

PostGrid Print & Mail Overview#

The PostGrid Print & Mail API offers seamless print and mail solutions, enabling the automation of sending personalized letters, postcards, checks, and more. With this API, you can systematize direct mail campaigns, transactional mailings, or on-demand dispatch without managing printing infrastructure. In Pipedream, you can harness this capability to interlace PostGrid with an array of other services and triggers, creating workflows that respond to events such as form submissions, scheduled campaigns, or customer actions.
