Q: iAd download conversion tracking

Yes. You'll know exactly how many impressions and downloads were associated with your campaign.

But I have a deep doubt here...

I want to track my campaing through an external ad server. My ads have been rejected because I coudn't use a third party tracking to follow my downloads in an external platform.

I've setted up my campaing direct to my third party tracked URL, but my aim here is getting app downloads.

Isn't it allowed to use a tracked URL with App Store final destination?? Any options here, please??

Thanks for your help!

which 3rd party have you ad server have you tried to use?
