(For steps on how to map custom HubSpot fields, please check out this article)

First, head to your Integrations tab and select your HubSpot settings. Click on the configuration button.

(NOTE: only Admin accounts will have access to view the Integrations tab)

You'll want to scroll to the Comment/Activity Tracking field at the bottom of your Other Settings. Select the button to the right to toggle the feature on.

Now, open any HubSpot deal mapped from PartnerPortal.io, and select Filter Activity. Select the PartnerPortal.io filter under Integrations. This will ensure you will have visibility on any activity.

(NOTE: Each user will have to enable this filter)
