Details#

This integration uses pre-built, source-available 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#

Changes to Specific Files on Google Drive

Description:Watches for changes to specific files, emitting an event when a change is made to one of those files. To watch for changes to [shared drive](https://support.google.com/a/users/answer/9310351) files, use the **Changes to Specific Files (Shared Drive)** source instead.

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 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`	Defaults to `My Drive`. To use a Shared Drive, use the Changes to Specific Files (Shared Drive) source instead.
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.
Files	`files`	`string[]`	Select a value from the drop down menu.
Minimum Interval Per File	`perFileInterval`	`integer`	How many minutes to wait until the same file can emit another event. If set to `0`, this interval is disabled and all events will be emitted.
Types of updates	`updateTypes`	`string[]`	Select a value from the drop down menu:`{ "label": "'sync' - A channel was successfully created. You can expect to start receiving notifications for it.", "value": "sync" }{ "label": "'add' - A resource was created or shared.", "value": "add" }{ "label": "'remove' - An existing resource was deleted or unshared.", "value": "remove" }{ "label": "'update' - One or more properties (metadata) of a resource have been updated.", "value": "update" }{ "label": "'trash' - A resource has been moved to the trash.", "value": "trash" }{ "label": "'untrash' - A resource has been removed from the trash.", "value": "untrash" }{ "label": "'change' - One or more changelog items have been added.", "value": "change" }`

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.

Maestra Overview#

The Maestra API lets you automate the transcription, captioning, and voiceover of videos and audios, crucial for creating accessible and localized content. With Pipedream, you can build workflows that trigger on various events to streamline media processing, integrate with other services, and manage content efficiently. Pipedream's serverless platform offers a code-free way to connect the Maestra API with hundreds of other apps, enabling you to create custom automation without the heavy lifting.
