Automatically Send SMS to customers after finishing a call

Use Toky webhooks to send an SMS after a customer finishes an inbound or outbound call

What you can get

This is what you can get with this sample:

  1. After an inbound or outbound call finish in your Toky call center, our system will automatically report the event to a registered service for the new_call event.
  2. Your registered service will receive the new_call data and it will send a custom SMS to the caller's phone number.

This sample can be used to automatically send surveys, marketing information, coupon codes etc.

Server code in PHP

You need to create a REST web service that you can't register later as a Toky webhook for the new_call event. This is a typical request for this event:

    "callid": "6a3c8sd112ochev3ru9b",
    "direction": "Outbound",
    "web_call": "no",
    "agent": "[email protected]",
    "duration": "12",
    "state": "completed",
    "contact_name": "Jhon Doe",
    "contact_email": "[email protected]",
    "contact_id": "247578",
    "to_number": "+1-202-5550174",
    "from_number": "+16175550115",
    "date": "2019-11-26 14:24",
    "record_url": "",
    "record_url_raw": "",
    "caller_name": "",
    "caller_email": "",
    "caller_country": "",
    "caller_phone_number": "",
    "reply_code": "200",
    "error_message": "",
    "ivr_option_pressed": null,
    "answered_time": 17,
    "in_queue_duration": 0


API Endpoint used


Parameters you need to replace in this web service:

  • [[TOKY_API_KEY]]: You can get the Toky API on this link:
  • [[TOKY_SMS_PHONE_NUMBER]]: This is the phone number in Toky, enabled to send SMS text messages. It should be entered in the international format, for example: + 18443326433
  • [[AGENT_EMAIL]]: It is the email of the agent to whom you want to be assigned SMS sent in Toky.
//header("Content-Type: application/json; charset=UTF-8");
//get request data
$data =file_get_contents('php://input');
//Convert data to object
$obj = json_decode($data,true);

//Ignore web calls
if ($obj["web_call"]=="no"){
    //Define destination phone number
        //If Inbound the SMS is sent to the source phone number
        $destPhoneNumber =$obj["from_number"];
      //If Outbound the SMS is sent to the destination phone number
        $destPhoneNumber =$obj["to_number"];
    // Message to send to the customer, it can be customized with the webhook data
    $message ="Hello, thank you for contacting Toky, visit to learn more about us.";

//function to send SMS
function sendSMS($phoneNumber,$textMessage)
  // create a new cURL resource
  $ch = curl_init();
  $smsPhoneNumber = "[[TOKY_SMS_PHONE_NUMBER]]";
  $api_key = '[[TOKY_API_KEY]]';
  $headers = array();
  $headers[] = "X-Toky-Key: {$api_key}";
   $data = array("from" => $smsPhoneNumber, "email" => "[[AGENT_EMAIL]]",
                   "to" => $phoneNumber,
                   "text" => $textMessage);

   $json_data = json_encode($data);

    // set URL and other appropriate options
    curl_setopt($ch, CURLOPT_URL, "");
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch,CURLOPT_POSTFIELDS, $json_data);
    curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
    curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/cacert.pem");

    $curl_response = curl_exec($ch); // Send request
   curl_close($ch); // close cURL resource

   $decoded = json_decode($curl_response,true);
   //Return error message if the message can't be sent
   if (!$decoded["success"]){
     $result= "Error sending SMS '$textMessage' to $phoneNumber: ".$decoded["error_message"];
     $result='SMS sent successfully';
	return $result;


Now that you have a web service you can register it in Toky to start receiving events after every call is finished. To register your webhook you can follow the steps on this article
