title: PayPal payments with both PayPal Accounts and Credit Cards on iOS as a third-party merchant
body: <p>I'm trying to add payments to an iOS App I'm developing, where some people sell physical goods, and other ones buy them, but I didn't find any solution that fits my needs.</p>
  
  <p>Currently, I've added the <a href="https://developer.paypal.com/webapps/developer/docs/classic/mobile/gs_MPL/">PayPal MPL SDK</a>, as described <a href="https://developer.paypal.com/webapps/developer/docs/classic/mobile/ht_mpl-itemPayment-iOS/">here</a>. </p>
  
  <p>However, the MPL library seems to <strong>not</strong> provide Credit Card support, furthermore its graphic is so outdated on iOS7.</p>
  
  <p>Other options I found are:</p>
  
  <ul>
  <li><p><strong><a href="https://github.com/paypal/PayPal-iOS-SDK">PayPal iOS SDK</a></strong>, but it's based on the <em>REST API</em>, while I need to support third-party payments and eventually chained/parallel payments, and all these features are not available with the <em>REST API</em>.</p></li>
  <li><p><strong><a href="https://developer.paypal.com/webapps/developer/docs/classic/products/mobile-express-checkout/">PayPal MEC</a> (Mobile Express Checkout)</strong>, using it inside an <code>UIWebView</code>.</p>
  
  <p>Even if it does provide both Credit Card &amp; PayPal Account as payment methods, I didn't find any way to support third-party payments (a.k.a. me/the app being the <code>API Caller</code> with another PayPal account being the <code>Receiver</code>).</p>
  
  <p>Furthermore, MEC <a href="https://developer.paypal.com/webapps/developer/docs/classic/express-checkout/integration-guide/ECOnMobileDevices/#id3817a5d1-ab29-41d1-89bb-5d71370409d0">does not support parallel payments</a>, multiple receivers, etc., but for now this would not be a problem, If I only could use it with <strong>third-party</strong> payments.</p></li>
  <li><p><strong>PayPal Adaptive Payments API</strong>, I even tried to use PayPal <strong>AP API</strong> without the SDK given by PayPal, obtaining the <code>payKey</code> server-side and loading <code>https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&amp;paykey=AP-KEY</code> inside an <code>UIWebView</code> by myself. </p>
  
  <p>However this page hasn't a <strong>mobile</strong> version, so it's simply unusable. </p>
  
  <p>I've tried even using the <em>embedded webflow</em>, the one with <code>&amp;extType=mini</code>, but it looks awful. Just not designed for this.</p></li>
  </ul>
  
  <p>In conclusion my question is: </p>
  
  <p>How can I support both <strong>credit cards &amp; paypal accounts</strong> payment methods, on <strong>mobile devices</strong>  (iOS in this case), if I need to handle them as a <strong>third-party merchant</strong>?</p>
