I am using php soap api to create OTRS tickets . Tickets gets created but autoreply is not going to the customers. here is my code.

$url = "https://otrs.com.np/otrs/rpc.pl"; // URL for OTRS server
$username = "ctdeveloper"; // SOAP username set in sysconfig
$password = "ctdeveloper"; // SOAP password set in sysconfig

$typeID = 2; // id from ticket_type table
// $queueID = 2; // id from queue table
// $priorityID = 1; // id from ticket_priority table
$ownerID = 1; // id from users table


### Form Fields

$user = $_POST['username_id'];
$queueID = $_POST['queue'];
$issue_type = $_POST['issue_type'];
$subject = $_POST['subject'];
$title = $user.'-Issue With'.' '.$issue_type.' -'.$subject;
$description = $_POST['description'];
$category = $_POST['category'];
$priorityID = $_POST['priority'];
$to = $_POST['to'];

'style' => SOAP_RPC,
'use' => SOAP_ENCODED
)
);

#### Create a new ticket shell. The function returns the Ticket ID ####
$TicketID = $client->__soapCall(
"Dispatch", array($username, $password,

"TypeID", $typeID,

)
);

# Use the Ticket ID to retrieve the Ticket Number.
$TicketNum = $client->__soapCall("Dispatch",

));


# Make sure the ticket number is not displayed in scientific notation
$big_integer = 1202400000;
$Formatted_TicketNum = number_format($TicketNum, 0, '.', '');


# Print the info to the screen.


echo "<script>alert('You have successfully created ticket number $Formatted_TicketNum.')</script>";
