Hello, is it possible to fetch contact list sizes for given dates with the /analytics endpoints? The :object_type endpoint (https://developers.hubspot.com/docs/methods/analytics/get-analytics-data-by-object) doesn't provide support for "contact-lists".
No, it's not possible to retrieve historical contact list sizes via an API at this time. This data is currently only available in a list's Performance tab.
The closest thing I know of in the API is the
lastSizeChangeAt field returned by the Contact Lists API.
Apologies for the delayed response. I appreciate your patience while I was out of office for the holiday.
It's possible to retrieve list size information without pulling the contact records themselves. As I mentioned earlier, this endpoint returns a
lastSizeChangeAt timestamp. I imagine Databox is polling this endpoint to keep track of list size changes.
