title: Am I allowed to offer payments with a 3rd party payment gateway, for my iPhone app?
body: <p>So I have a RESTful Api service which has free and pay'ed stuff. Anyone can create an iPhone/Andriod/MSPhone app that leverages our api.</p>
  
  <p>Bad analogy: imagine we're creating a chat api service for Steam .. and you can pay for more people in your friends list, instead of getting them via steam-experience/steam-levels. So now anyone can create a chat <em>client</em> (on any platform) .. and they use our REST api.</p>
  
  <p><strong>So, for anyone creating an iPhone app, are we allowed to accept credit card details</strong> and HTTPS POST them to our webserver .. where we call another payment gateway (eg. Stripe, paypal, etc.) to do the processing. </p>
  
  <p><em><strong></em> WE NEVER STORE ANYTHING **</strong> (besides the receipt from Stripe, etc.)</p>
  
  <p>Are well allowed to program this into our iPhone app? Or is that illegal? 
  Can we also offer bitcoins as a payment option?</p>
  
  <p>(Note: we're not really using Stripe .. but they are a well known payment processor, which helps explain this question). </p>
