How do I find the website ID, also called idSite or Site ID?

Every added in Piwik PRO website has its own ID. To find out its value just click on your login in right upper corner of the site and then on “Websites button”. The ID will be visible right under the provided name of the page:
Piwik PRO Standalone uses numeric siteID while PPMS uses new hexadecimal UUID.
