While connecting my own data collection endpoint to PiwikPro via HTTP API I saw the examples at https://developers.piwik.pro/en/latest/tracker/http_api.html#/paths/~1ppms.php/get that show how to use the _cvar and cvar parameters.
I am confused by the fact that the value should be a stringified JSON object but the examples use comma delimited lists like
values sent in this strange format do not appear in the Tracker-Debugger. I tried the example and a mor simple one like
1,debugHttpApi,on in some test hits but I had to change the format (as expected) to JSON. I used
%7B%221%22%3A%5B%22debugHttpApi%22%2C%22on%22%5D%7D to be precise in order to to see something coming through.
Is this just a simple error in the documentation or am I missing something here?
