Segment VisitsSummary by events returns all values equal to 0

Support & Bugs
#1

I am using piwik hosted on innocraft. I have a javascript card that can be iframed on a page and have a few events associated with clicks on certain parts on the card. The events are logged in my piwik dashboard and I can get data for all events using a get request of the form

https://protograph.innocraft.cloud/?
module=API&
format=json&
idSite=2&
period=range&
date=2017-01-01,today&
method=Events.getCategory&
secondary_dimension=eventAction&
token_auth=my_auth_token

However I want data of visitors scoped by an event action or event name for which I try

https://protograph.innocraft.cloud/?module=API&
method=VisitsSummary.get&
idSite=2&
date=yesterday&
period=day&
format=json&
filter_truncate=5&
language=en&
segment=eventAction==start&
token_auth=my_token_auth

This is exactly as is given in the example on https://developer.piwik.org/api-reference/reporting-api-segmentation. This however gives me a result in the form

{
    "nb_uniq_visitors": 0,
    "nb_users": 0,
    "nb_visits": 0,
    "nb_actions": 0,
    "nb_visits_converted": 0,
    "bounce_count": 0,
    "sum_visit_length": 0,
    "max_actions": 0,
    "bounce_rate": "0%",
    "nb_actions_per_visit": 0,
    "avg_time_on_site": 0
}

What could be the issue here

Hi there,

It seems the issue may be that there is no data for the day? For example after changing the eventAction and the ID Site we are seeing data:

https://protograph.innocraft.cloud/?module=API&method=VisitsSummary.get&idSite=1&date=2017-01-01,today&period=day&format=json&filter_truncate=5&language=en&token_auth=&segment=eventAction%3D%3Dloaded

Hope this helps.
