Ads data APISOLVE
Feb 15, 2019 10:14 AM
At this time, ads data cannot be retrieved via HubSpot APIs.
To begin with, much of the data that factors into those metrics comes directly from the ad networks' APIs (Google, Facebook, LinkedIn). The HubSpot ads tool then combines the data with contact, analytics, and form submission information to calculate conversion rates and other metrics.
That said, I do see the use case for pulling these finished metrics from HubSpot.
