How do I track app install traffic sources?
 

Say I have 3 different Marketing Campaigns A,B,C

These campaigns drive traffic to a Opt-In Page, where the lead enters email to receive app download link.

lead receives link from email and proceeds to download the app on phone. Installs app, uses facebook/email to register and login the app.

I know that app conversion activity can be tracked with adwords SDK,

But if say I have 10 new installs today, how do i know which Campaign A,B,C did they come from?

Appreaciate any advice / help.
Cheers.

You need to capture the install button click event.
