iOS: How to get install referrer source

Question

I want to find out how the user installed the app using what source (attribution).

For Android, it's possible to get the referrer's URL, but I haven't found an obvious way for iOS. There are external services such as AppsFlyer (http://support.appsflyer.com/entries/69796693-Accessing-AppsFlyer-Attribution-Conversion-Data-from-the-SDK-Deferred-Deep-linking-) that let's you do this.

I noticed that starting iOS 8, developers could append the publisher id and the campaign id to the App Store URL for iTunes Connect Analytics (http://www.applift.com/blog/new-era-attribution-analytics.html). Is it possible to get the campaign id and the publisher id inside the app? I couldn't find any API changes or resources on this.

Any help would be appreciated. Thanks.

Answer 1

This has to be solved/implemented by Apple. If another company is coming out and saying they can solve this (Branch, etc.), they aren't being completely truthful.

The issue is that iTunes doesn't pass a referrer into the app, so without passing them the iOS IDFA on the click (redirect or out-of-bounds) every tracking method has to rely on Fingerprinting which drops off in attribution accuracy significantly past 24 hours.
