I use the following software versions
Piwik version: 3.1.1
MySQL version: 5.7.19
PHP version: 7.0.23
With the extended campaigns plugin.
I am using the HTTP Tracking API to import data into our new piwik testing appliance.
If the URL in the tracked action looks like the following
Only the first tag “utm_source” appears in Piwik.
I have already tried to switch utm_campaign with utm_medium and then I get the the info of utm_campaign in the vistiors and campaign logs.
What am I missing here?
