This card starts a Flow whenever an existing lead on a certain list in Marketo is updated.
- _List ID: _the ID of the list in Marketo that you would like to monitor for updates. The Flow will only run when a lead on this list is updated. You can find the ID of the list in the URL. For example, if the URL of the list in Marketo is https://app-ab08.marketo.com/#ST**1038**A1, then the _List ID _would be 1038.
The outputs on this card are dynamically generated. After you authenticate, the card will be automatically populated with the default Marketo fields for the “Lead” record, and the custom fields you have added to Marketo.
