The following php example helps you get the address verfication using the USPS web service. You only need to set the Lincence Number, User ID and Password.
Code Example:
<?php
$xml_string = "";
$xml_string = "<?xml version=\"1.0\" ?>";
$xml_string .= "<AccessRequest xml:lang=\"en-US\">";
$xml_string .= "<AccessLicenseNumber>LICENCE_NUMBER</AccessLicenseNumber>";
$xml_string .= "<UserId>USER_ID</UserId>";
$xml_string .= "<Password>PASSWORD</Password>";
$xml_string .= "</AccessRequest>";
$xml_string .= "<?xml version=\"1.0\" ?>";
$xml_string .= "<AddressValidationRequest xml:lang=\"en-US\">";
$xml_string .= "<Request>";
$xml_string .= "<TransactionReference>";
$xml_string .= "<CustomerContext>Address Validation Request</CustomerContext>";
$xml_string .= "<XpciVersion>1.0001</XpciVersion>";
$xml_string .= "</TransactionReference>";
$xml_string .= "<RequestAction>AV</RequestAction>";
$xml_string .= "</Request>";
$xml_string .= "<Address>";
$xml_string .= "<CountryCode>US</CountryCode>";
$xml_string .= "<City>Escondido</City>";
$xml_string .= "<State>CA</State>";
$xml_string .= "<PostalCode>92082</PostalCode>";
$xml_string .= "</Address>";
$xml_string .= "</AddressValidationRequest>";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,"https://onlinetools.ups.com/ups.app/xml/AV"); /// the url to post to without the ?query+string
curl_setopt ($ch, CURLOPT_HEADER, 0); /// header control
curl_setopt($ch, CURLOPT_POST, 1); // tell curl to do a POST, not a GET
curl_setopt($ch, CURLOPT_VERBOSE, 1); // tell curl to do a verbose
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // tell curl to do a verbose
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_string); /// the query string goes here as set in the variable above
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); /// allows it to set the response in a variable - $xyz
curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml;')); /// allows it to set the response in a variable - $xyz
$myresult = curl_exec ($ch); /// execute the curl session and store the response in the variable $xyz
curl_close ($ch); /// close the curl session
echo htmlentities($myresult);
?>
