Is there a way to trigger a Workflow based on how a Contact was created?

e.g. We are using the Contact API to create a Contact record from an outside source. This Activity/Engagement gets created.

How can I use this to trigger a another Workflow in HubSpot?

Hi @skylergast

The information reflected in that timeline entry is stored in the contact’s original source drilldown properties, which you can use to trigger workflows: [Understand ‘Original source drill-down’ properties](https://knowledge.hubspot.com/reports/what-do-the-properties-original-source-data-1-and-2-mean)

Hope this helps.
