title: Using prepaid credits in iOS apps
body: <p>we are developing an iPhone app as an extension of a classifieds system (web site). On that web site users can buy (prepaid) credits and use them to boost and promote their ads. Will Apple reject our app if we implement consumption of credits? We are not gonna allow buying the credits, just using them (users will still have to buy credits on the web site). </p>
  
  <p>Only worrying thing I found is item 11.2 in App Store review guidelines: </p>
  
  <blockquote>
    <p>11.2 Apps utilizing a system other than the In-App Purchase API (IAP) to purchase content, functionality, or services in an App will be
    rejected.</p>
  </blockquote>
  
  <p>Is there a way to contact Apple directly regarding this question?</p>
  
  <p>And a add-on question. I suppose we can implement a payment gateway system like Amazon and Ebay and get a way with buying credits? I don't see any restrictions in guidelines regarding non in-app purchase system.</p>
