SWP - Checkout

A date-time value (since 01/01/0001 00:00:00) that marks the day and time the request was sent to Checkout in ticks. Checkout will only accept utc_time values that are 20 minutes before the current time or 10 minutes after the current time. Requests expire after 10 minutes to prevent malicious users from capturing requests and resubmitting them at a later time.

Checkout provides an API that returns the correct UTC time from Forte’s server. Using this server-side value prevents inadvertent expiration errors from client PCs that do not have the correct local time set.

Use the following getUTC API URLs in your code to retrieve UTC ticks from Forte's servers:

• https://checkout.forte.net/getUTC?callback=? //production

• https://sandbox.forte.net/checkout/getUTC?callback=? //sandbox

The following script returns the correct UTC time for the hash:

<script>  var button = $('button[api_access_id]');  $.getJSON('https://sandbox.forte.net/checkout/getUTC?callback=?').done(function (utc) {  button.attr('utc_time', utc);  });  </script>

You can also use the following PHP/Curl code sample to fetch the UTC time from the getUTC API URL displayed above (e.g., ?(XXXXXXXXXXXX643793); where XXXXXXXXXXXX643793 is the UTC time value).

<?php
    function utc() {
        $curlUTC = curl_init();
        curl_setopt($curlUTC, CURLOPT_URL, 'https://checkout.forte.net/getUTC?callback=?');
        curl_setopt($curlUTC, CURLOPT_BINARYTRANSFER, true);
        curl_setopt($curlUTC, CURLOPT_RETURNTRANSFER, true);
         $curlData = (curl_exec($curlUTC));
        $positionOfOpeningParenthesis = stripos($curlData,"(");
        $positionOfClosingParenthesis = stripos($curlData,")");
        $utc =  substr($curlData,$positionOfOpeningParenthesis+1,$positionOfClosingParenthesis-2);
        return $utc;
        curl_close($curlUTC);
    }
