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
Dropbox	`dropbox`	`app`	This component uses the Dropbox app.
Path	`path`	`string`	Select a value from the drop down menu.
Recursive	`recursive`	`boolean`	Also watch sub-directories and their contents.
	`includeMediaInfo`	`boolean`	Emit media info for photos and videos (incurs an additional API call)
	`includeLink`	`boolean`	Emit temporary download link to file (incurs an additional API call)
	`dropboxApphook`	`$.interface.apphook`
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between component invocations.

Trigger Authentication#

Dropbox uses OAuth authentication. When you connect your Dropbox account, Pipedream will open a popup window where you can sign into Dropbox and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Dropbox API.

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