How can I get the IP of the visitor in my google analytics account? The API of GA https://developers.google.com/apis-explorer/#p/analytics/v3/ provide many information about the location of the visitor such as city, country, etc.. all of them all derived by the IP, However I didn't find the way to get the IP.
Note : I am using the v3 API of GA.
No, GA does not expose the visitors IP anywhere (also in some jurisdictions - e.g. all of the European Union - IP is considered personally identifiable information and would not allowed to be stored unless anonymized by cutting of a part of it, which would probably defy your purpose). Generally, if things are not in the list of dimensions and metrics (and the BigQuery export schema for GA Premium accounts) then they are not available
