Signature Verification

To confirm that the data that we are sending is authentic and comes from VoPay rather than a party pretending to be VoPay we will send you a ValidationKey. This ValidationKey is a combination of your API shared secret key and the record ID (i.e., Transaction ID, eLinx Request ID, etc) codified by HMAC SHA1

function calculateKey($apiSharedsecret, $ID)  
{  
    return sha1($apiSharedsecret . $ID);  
}

$calculateKey = calculateKey('IUAz1NGoyM02VsoODfIzQA==', '1');  
if ($calculateKey == $validationKey) {  
    // Validation Key Ok.  
} else {  
    // Invalid Validation Key. Ignore the webhook  
}
