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.
Board	`board`	`string`	Select a value from the drop down menu.
List	`list`	`string`	Select a value from the drop down menu.
Cards	`cards`	`string[]`	Select a value from the drop down menu.

Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Trello API.

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