title: Credit card processing with Quickbooks Payments API
body: <p>I've been trying for several days to find PHP sample code or a PHP-based SDK for <a href="https://developer.intuit.com/docs/0100_QuickBooks_Payments" rel="nofollow noreferrer">Quickbooks Payments API</a> to integrate credit card processing into an e-commerce site to no avail.</p>
  
  <p>I have found the <a href="https://github.com/intuit/QuickBooks-V3-PHP-SDK" rel="nofollow noreferrer">Quickbooks Online API PHP SDK</a> but it doesn't seem to handle the raw credit card processing I need, only a way to log general payments into Quickbooks Online.</p>
  
  <p>Does anyone have an example of authentication, token generation, and subsequent credit card processing using PHP for Quickbooks Payments API?</p>
