                  1) Click on ‘Checkout with PayPal’ button and see the experience.
                  <br>
                  2) If you get any Firewall warning, add rule to the Firewall to allow incoming connections for your application.
                  <br>
                  3) Checkout with PayPal using a buyer sandbox account provided on this page. And you're done! Or you can use Proceed to Checkout for Express Checkout Mark flow.
                  <br>
                  4) The sample code uses default sandbox credentials which are set in paypal_config.php. You can create your own credentials by creating PayPal Seller and Buyer accounts on Sandbox  <i><a href="https://developer.paypal.com/webapps/developer/applications/accounts/create" target="_blank">here</a></i>.
                  <br>
                  5) Make following changes in paypal_config.php:<br>
                  - If using your own Sandbox seller account, update PP_USER_SANDBOX, PP_PASSWORD_SANDBOX and PP_SIGNATURE_SANDBOX values with your sandbox credentials<br>
                  - SANDBOX_FLAG: Kept true for working with Sandbox, it will be false for live.<br>
                  </p>
               <h4 id="incontext"> In-Context Checkout integration steps: </h4>
               1) Copy the files and folders under 'Checkout' package to the same location where you have your shopping cart page.
               <br>
               2) Copy the below  &lt;form&gt; .. &lt;/form&gt; to your shopping cart page.
               <br><br>
   <pre><code>&lt;form id="myContainer" action="paypal_ec_redirect.php" method="POST"&gt;
      &lt;input type="hidden" name="PAYMENTREQUEST_0_AMT" value="10.00"&gt;&lt;/input&gt;
      &lt;input type="hidden" name="currencyCodeType" value="USD"&gt;&lt;/input&gt;
      &lt;input type="hidden" name="paymentType" value="Sale"&gt;&lt;/input&gt;
      <i>&lt;!--Pass additional input parameters based on your shopping cart. For complete list of all the parameters <a href="https://developer.paypal.com/webapps/developer/docs/classic/api/merchant/SetExpressCheckout_API_Operation_NVP/" target=_blank>click here</a></i> --&gt;
&lt;/form&gt;</code></pre><br>
               3) Include the following script on your shopping cart page:
               <br><br>
   <pre><code>&lt;script type="text/javascript"&gt;

 var formdata = {PAYMENTREQUEST_0_AMT: 10 , paymentType:'SALE', PAYMENTREQUEST_0_CURRENCYCODE: 'USD'};

 paypal.Button.render({

        env: 'sandbox',  // sandbox | production

        locale: 'en_US',

        style: {
        size: 'small',   // tiny | small | medium
        color: 'gold',    // gold | blue | silver
        shape: 'pill',    // pill | rect
        label: 'checkout' // checkout | credit
        },

        payment: function(resolve) {
            jQuery.post(CREATE_PAYMENT_URL,formdata,function(data) {
                resolve(data); // no data.token, b/c data.token is json format
            });
        },

        /* Optional: show a 'Pay Now' button in the checkout flow rather than Continue */
        commit: true,

        onAuthorize: function(data, actions) {

            var EXECUTE_PAYMENT_URL = 'SetExpressCheckout_URL';

            jQuery.post(EXECUTE_PAYMENT_URL, { payToken: data.paymentID, payerId: data.payerID }, function(response) {

                //if funding error restart
                if (response === '10486') {
                    actions.restart();
                }
                //success
                actions.redirect();
            });
        },

        onCancel: function(data, actions) {

        }

    }, '#paymentMethods');
}
 &lt;/script&gt;
 &lt;script src="//www.paypalobjects.com/api/checkout.js" &gt;&lt;/script&gt;</code></pre><br>
               4) Open your browser and navigate to your Shopping cart page. Click on 'Checkout with PayPal' button and complete the flow.<br>
               5) Read more details on Express Checkout API <a href="https://developer.paypal.com/webapps/developer/docs/classic/products/#ec" target=_blank>here</a>.<br>
               6) Use of "commit: true" to see "Pay Now" on PayPal Checkout screen is highly recommended to increase buyer conversion rate. <br>
               7) For more upgrade details refer <a href="https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/upgrade-integration/" target=_blank>Checkout.js v4 Upgrade Guide</a>.
