Simple payment example that uses the 'echo' feature to return the created resource data.

paymentEcho.php

<?php

  require 'ConfigFactory.php';
  require 'OAuthRequest.php';
 
  $c = new Creds();
  $creds = $c->creds();
  $links = $c->links();
  $accessTokenData = getAccessToken($links, $creds);
  
  $info = array(
     "merchantId" => $c->merchantId(),
     "tenderType" => "Card",
     "amount" => '',
     "cardAccount" => array(
       "number" => '',
       "expiryMonth" => '',
       "expiryYear" => '',
       "CVV" => '',
       "avZip" => ''
     )
  );
  /*
  * Without including the echo=true query parameter, you're returned the Id of the payment in the Location Header
  * Including it, it is returned with the response. Uncomment the below associative array to see affect on response.
  */
  $queryParams=array(
      "echo"=>"true"
  );
  $postPayment = new OAuthRequest($links['payment'],$creds, $accessTokenData, $queryParams);
  $postPayment->createHeader($info);
  echo $postPayment->sendRequest($info);
