I have some ads on my Facebook and Instragram accounts and I'd like to track these downloads.
For Facebook I guess I should install the SDK (https://github.com/facebook/react-native-fbsdk) but I can't fin any method to save this information. Same thing for Instragram.
If this is something we need to track when we get redirected to the store to download the app, how can check this inside the app? This is more something we need to track on Facebook/Instragram dev panel, right? Maybe here is where I'm getting confused.
Also I saw that I can create ads campaings in Facebook Ads Manager. Does it mean that I can only measure downloads using these kind of ads? What about from a link on a normal Facebook post?
I'm using React Native.
You can check the LoginManager from the react-native-fbsdk.
You can use some service like Localytics or Adjust to track the events.
You can use Sentry to send crash reports in case you are failing to register/login/logout. You can also use GTM.
Using these three services will give you a lot of power (tracking and crash reports).
Take a look at the topic deferred deep linking facebook, that's what you'll need if you are planning to have Ads from facebook.
