title: iOS Conversion / installation Tracking
body: <p><strong>Objective:</strong> i want to fetch my custom parameter(referrer) from iTunes link upon installation of my application in device.</p>
  
  <p><strong>iTunes</strong> links look somethings like this:
  <a href="https://itunes.apple.com/in/app/complete-gym-guide-lite/id550449574?mt=8" rel="nofollow noreferrer">https://itunes.apple.com/in/app/complete-gym-guide-lite/id550449574?mt=8</a></p>
  
  <p>If i append my parameter say(&amp;referrer=xyz)at the end and i open this url in ios safari browser then it will prompt to download the application.</p>
  
  <p><strong>Confusion:</strong> will app store send my parameter(referrer) to my application on launch so that i can fetch it in my application and use it.</p>
  
  <p>In case of <strong>Android play store</strong> link look like this: <a href="http://play.google.com/store/apps/details?id=" rel="nofollow noreferrer">http://play.google.com/store/apps/details?id=</a>&amp;referrer=guid%3D%guid%</p>
  
  <p>As you can see referrer parameter at the end of url. Once app is installed in device then play store will send this parameter to app using INSTALL_REFERRER broadcast receiver. We can use this parameter.</p>
  
  <p><strong>What i tried OR Other people doing for conversion tracking</strong>: Other people are simply sending static data to their server at the first time opening of app and maintain a flag in NSDefault to make sure that app does not send same data again. I can also do the same as well as alternate ways suggested in below links but i want to do something with custom parameter. </p>
