Tracking installs of APPs and attribute back to an affiliate ID

[dsavvy83]

Hi

I have been given a pixel to fire when an app is installed,
so the pixel that needs to be fired is when an installation happens and then grab the affiliate ID to fire the pixel, What i am not sure about is how this affiliate ID is passed into tealium? does iOS and Andrioid pass affliate tracking links which i am not aware of?
Or does that require the app developers to capture this data and pass it into the datalayer?

thanks for your help
