We’re looking to pull in Campaign level Reporting Data and the information here - http://developers.hubspot.com/docs/methods/email/get_campaign_data - looks spot on.
However, one question comes to mind - is there a way to know when this email was sent? Or what the date of this specific email send corresponds to?
We’re interested in pulling in campaign data but have found that metric updates (opens, clicks, etc.) seem to trail off 15 - 30 days after send. That being said, it would be awesome to only make update requests for Campaign IDs that have been sent within the last X days so as to not unnecessarily tax the API for un-changeing statistics for pretty old Campaign IDs.
Let me know your thoughts!
