Hi,
Thanks for reaching out. With regard to your concern, when you pull the historical data report, the API just pulls from the UI at the time you report right, so there's obviously gonna be a discrepancy. To correct the discrepancy you will just have to pull again from the API. I
would recommend keeping an eye on our Developer Blog for information on future releases.
Let me know if you have any questions.
Thanks,
