Leads created by BrightTALK in HubSpot will have a default Lead Source of "Offline Sources" We recommend updating this so that you can easily distinguish between leads created by BrightTALK and leads created by other API integrations. To do this, you can utilize a single Workflow:
Once this Workflow is active, all leads created in the last day that have a BrightTALK User ID will have a default Lead source of "BrightTALK." Feel free to change the final parameter to whatever you need it to be (i.e. instead of "BrightTALK", you could do "BrightTALK Webinar").
