Why monthly Unique visitors differ from the sum of daily unique visitors of that same month?

(Reinoud) #1

Could you explain me why the amount of monthly unique visitors differs from the sum of the daily unique visitors of that same month? Example: if I export the main metrics by month, the amount of unique visitors for December 2017 is 26.006. If I export the main metrics table by day and I sum up the unique visitors of the 31 days of December 2017, I get 36.311 unique visitors for that month…
Many thanks in advance,

Have you tried doing the same with an HTTP REST request? The values that you enter for the &date and &period parameters might offer a clue.

Hi - I have the same error, the count of unique visitors are different when I filter by date range and month. How do I do a HTTP REST request?

Thanks much,

Hi, Kausaliya!

Matomo has changed the manual and I can no longer find all of the pages that I used to teach myself how to retrieve data on my own. The best that I can offer at this time is the following page and example.

You must supply your own authorization code and path.
