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:

Discord Overview#

The Discord API interacts seamlessly with Pipedream, empowering you to craft customized automations and workflows for your Discord server. With this powerful integration, you can automate tasks like message posting, user management, and notifications, based on a myriad of triggers and actions from different apps. These automations can enhance the Discord experience for community moderators and members, by synchronizing with external tools, organizing community engagement, and streamlining notifications.

Label	Prop	Type	Description
Discord	`discord`	`app`	This component uses the Discord app.
channel	`channel`	`$.discord.channel`
Message	`message`	`string`	Enter a simple message up to 2000 characters. This is the most commonly used field. However, it's optional if you pass embed content.
Thread ID	`threadID`	`string`	If provided, the message will be posted to this thread
Username	`username`	`string`	Overrides the current username of the webhook
Avatar URL	`avatarURL`	`string`	If used, it overrides the default avatar of the webhook. Note: Consecutive posts by the same username within 10 minutes of each other will not display updated avatar.
Include link to workflow	`includeSentViaPipedream`	`boolean`	Defaults to `true`, includes a link to this workflow at the end of your Discord message.
Suppress notifications	`suppressNotifications`	`boolean`	Defaults to `false`, sends the message as silent, triggers no notifications to clients.
Embeds	`embeds`	`any`	Optionally pass an array of embed objects. E.g., {{ [{"description":"Use markdown including Italic bold __underline__ ~~strikeout~~ [hyperlink](https://google.com) `code`"}] }}. To pass data from another step, enter a reference using double curly brackets (e.g., `{{steps.mydata.$return_value}}`). Tip: Construct the `embeds` array in a Node.js code step, return it, and then pass the return value to this step.
