title: How can I process Apple pay in react native
body: <p>It's my first time to use apple pay. I'm using react-native-payments library and I could get paymentToken but I cant understand how I can perform a payment process.
  The payment provider companey <strong>hyperpay</strong> provided me <strong>entity Id</strong> and <strong>Access token</strong> but I don't know how to use them, which information I'll send, for any link I will send information and which response I'll get. This is the function does Payment process as documentation mentioned</p>
  <pre><code>paymentRequest.show()
   .then(paymentResponse =&gt; {
     const { paymentToken } = paymentResponse.details;  
  
     return fetch('...', {
       method: 'POST',
       body: {
        paymentToken
       }
    })
  .then(res =&gt; res.json())
  .then(successHandler)
  .catch(errorHandler);
  });
  </code></pre>
