Postbacks
In addition to receiving attribution information from these ad networks,
Firebase Analytics can report back information to these ad networks, in a
concept known to most marketing professionals as "completing the circle of
life". Actually, nobody calls it that; I just made it up. (But it sounds good,
right?) You can ask Firebase to tell these ad networks that a user has completed
an important conversion event within your app, which is done via a call known as
a Postback.
