When you are running an Intent Lead Campaign with BrightTALK, you will see this Campaign appear under the Marketo Programs section in your Connector. By clicking "Connect", you'll see the option to connect this Campaign directly to an existing Marketo Program.
In order for data to sync, you'll also need to make sure this field is mapped:
|Campaign Leads- Campaign Reference||String||String field used to store the name of the Marketo membership program for Summit and Intent Leads|
Please note: BrightTALK requires that the Program type for Intent Leads be "Default." In addition, the Program should contain the Status "Engaged" or otherwise, the sync may fail. Here is a sample Channel template you can use for these Campaigns:
