How does facebook mobile app advertising work?

Question

Facebook

If someone advertised their mobile application through Mobile App Ads , tell me, payment for installation occurs upon installation, or even if the user clicked install, the appstore window opened and he closed it.
That is, if my application costs $2, I set the price of $1 per installation in the advertising campaign, will this dollar be charged if the user actually bought the application?

Answer 1

Facebook takes money for the install, no matter how much the app costs. If a user installed/purchased by clicking on the banner, facebook will charge you the price of the installation in his system
