Status Envelope
Name Type Description
mtstatus Status object Status
Status Object
Name Type Required Description

status string Required Billing/delivery status
hash string Required Hex (lowercase) encoded SHA1 HMAC from (id +

And these two sample demo codes:

FIRST:

<?php

define('CONFIG_HASH_KEY', 'ABCDEFGH');

try {

        // read json data
        $postdata = file_get_contents("php://input");
        $json = json_decode($postdata);
        $mosms = $json->mosms;

        // check hash
        $hashedStr = $mosms->id . $mosms->src_no . $mosms->dst_no . $mosms->gtw_type . $mosms->message;
        $hashedStr = hash_hmac('SHA1', $hashedStr, CONFIG_HASH_KEY);
        if($hashedStr != $mosms->hash) {
                throw new Exception('Hash error');
        }

        ////////////////////////////////////////////////////////////////////
        // process SMS
        // your code

        // response example
        $response = array(
                'status' => 'ok',
                'mtsms' => array(
                        'message' => 'Dakujeme za platbu',
                        'bill_key' => 'MYPAY-01-00',
                ),
        );

        // or
        $response = array(
                'status' => 'ok',
                'mtsms' => array(
                        'message' => 'SMS ste nenapisali v spravnom formate, prosim opravte sa...',
                        'bill_key' => 'MYPAY-00-00',
                ),
        );

        ////////////////////////////////////////////////////////////////////

        $hashedStr = $response['mtsms']['message'] . $response['mtsms']['bill_key'];
        $response['mtsms']['hash'] = hash_hmac('SHA1', $hashedStr, CONFIG_HASH_KEY);


}
catch(Exception $e) {                
        $response = array(
                'status' => 'error',
                'mtsms' => null,
        );
}

echo json_encode($response);

SECOND:

<?php

define('CONFIG_HASH_KEY', 'ABCDEFGH');

try {

        // read json data
        $postdata = file_get_contents("php://input");
        $json = json_decode($postdata);
        $mtstatus = $json->mtstatus;

        // check hash
        $hashedStr = $mtstatus->id . $mtstatus->status;
        $hashedStr = hash_hmac('SHA1', $hashedStr, CONFIG_HASH_KEY);
        if($hashedStr != $mtstatus->hash) {
                throw new Exception('Hash error');
        }

        ////////////////////////////////////////////////////////////////////
        // process status
        // your code

        if($mtstatus->status === 'D') {
                //SMS was billed and delivered
        }
        else if($mtstatus->status === 'E') {
                //SMS was NOT billed and delivered
        }
        else if($mtstatus->status === 'S') {
                //SMS was billed
        }
        else if($mtstatus->status === 'U') {
                //SMS was NOT  delivered
        }


        // response example
        $response = array(
                'status' => 'ok'
        );


        ////////////////////////////////////////////////////////////////////

}
catch(Exception $e) {                
        $response = array(
                'status' => 'error'
        );
}

echo json_encode($response);

Can anyone help me/guide me with implementing this into site, as i already said i want to "hide" either element of site behind this paywall or link, thanks in advance :)
