Example Request (JSON)

Example Code (PHP)

    $request = array(
        'command' => 'channel.currentchannels',
        'api_key' => '##API Public Key##',
        'timestamp' => time(),
        'cdn' => 158,
        'stream' => 'my_channel_stream_name',
        'appinst' => 'live'                     /* optional */
        
    );
        //Create request signature
    $json_request = json_encode($request);
    $sig = base64_encode(hash_hmac('sha256', $json_request,
        '##API Secret Key##', true));
    $request['signature'] = $sig;
    $json_request = json_encode($request);
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.scaleengine.net/stable/'); // Set the URL
    curl_setopt($ch, CURLOPT_POST, true); // Perform a POST
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // If not set, curl prints output to the browser
    curl_setopt($ch, CURLOPT_HEADER, false); // If set, curl returns headers as part of the data stream
    curl_setopt($ch, CURLOPT_POSTFIELDS, array('json' => $json_request)); //'Json' string or 'PHP' serialized return
    
    //If your PHP host does not have a proper SSL certificate bundle, you will need to turn off SSL Certificate Verification
    //This is dangerous, and should only be done temporarily until a proper certificate bundle can be installed
    //curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); // Turns off verification of the SSL certificate.
    //curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Turns off verification of the SSL certificate.
    
    $response = curl_exec($ch); //Execute the API Call
    if (!$response) {
        die('Failed to connect to ScaleEngine API');
    }
    
    //Decode the response as an associative array 
    $arrResponse = json_decode($response, true); 
    if ($arrResponse) {
        //Operation completed successfully
        //TODO Add work here
        print_r($arrResponse);
    } else {
        //Operation failed
        echo 'An error occured processing your request:';
        print_r($response);
    }
