The string below was sent to google analytics when the user clicks on a button:

"v=1&_v=j31&a=214989120&t=event&_s=2&dl=http%3A%2F%2FMyServer.amazonaws.com%2Fga.html&ul=en-us&de=UTF-8&sd=24-bit&sr=1920x1080&vp=1920x 895&je=1&fl=16.0%20r0&ec=button&ea=click&el=nav-buttons&_u=eCCAAEQFI~&jid=&cid=1 528855396.1420545392&tid=UA-XXXXXXXX-1&z=1765240355"

In the following url, there are parameters explanations: "https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters"

But i didn't find any explanations to parameter "a" (In my example: a=214989120).

Does anybody know what is the explanations of "a"?

Thanks!

I used the Chrome Google Analytics Debugger (by the GA team) which provided an answer to this: 

a=AdSenseId
