hi,
we use getCustomVariablesValuesFromNameId method to get stats about custom variables. we have extremely many custom variables, so we need a way to get just several of them. getCustomVariablesValuesFromNameId returns all custom variables, thats to much result …
is there a solution for that or should we just dublicate and hack this method?
what exactly do you want, all values for a custom variable name ? or a specific list of custom variable names ?
You can use the parameters &label= to restrict to a list of labels (comma separated), label can be custom variable name for example.
hi matt,
great thank you, this was exactly what I searched …
on the API page this (param. label is useable) was not descriped
You’re welcome, I updated the doc on: http://piwik.org/docs/analytics-api/reference to better show this parameter which is quite useful indeed 
matt,
I tried to add 2 values to &label → &label=10000,10001
I get no data. If I use only 1 value it works …
in docs writes:
but for the moment I use BulkAPI request, they work for now … but multiple label values would be nicer 
Happy New Year! If you are still using Piwik and interested in the awesome new feature of “Creating a Custom Segment in Piwik and apply to reports in Real time!” we need YOUR help, with a little or big donation at: http://crowdfunding.piwik.org/custom-segments-editor/
This will allow to dynamically add or edit, a new set of rules for example “Show all visitors from USA and using Firefox and using Google”. This will be done via a simple to use interface. See screenshots and more info here: http://crowdfunding.piwik.org/custom-segments-editor/
We are crowd funding the future of Piwik and this feature in particular. With your help we can do it.
Thanks
