PHP+BillDesk payment gateway integration issue

Question

I am trying to integrate BillDesk payment gateway with my PHP website. I am getting this below error when I run my simple PHP code

{"status":422,"error_type":"invalid_data_error","error_code":"GNIDE0004","message":"Invalid Content-type header"}

Here is my PHP code. Please note this is only for testing purpose

<?php
$str = "<MerchantId>|order45608988|NA|300.00|NA|NA|NA|INR|NA|TypeField1|<ClientID>|NA|NA|TypeField2|Txtadditionalinfo1|Txtadditionalinfo2|http://google.com";

$checksum = hash_hmac('sha256',$str,"<secretkey>", false); 
$checksum_value = strtoupper($checksum);


echo '<form action="https://pguat.billdesk.io/payments/ve1_2/orders/create" method="post" id="billdesk_payment_form">';
echo '<input type="hidden" name="MerchantId" value="<MerchantId>"/>';
echo '<input type="hidden" name="CurrencyType" value="INR"/>';
echo '<input type="hidden" name="SecurityId" value="<ClientID>"/>';
echo '<input type="hidden" name="txtCustomerID" value="order45608988" />';
echo '<input type="hidden" name="txtTxnAmount" value="300.00" />';
echo '<input type="hidden" name="txtAdditionalInfo1″ value="" />';
echo '<input type="hidden" name="RU" value="http://returnURL.com" />';
echo '<input type="hidden" name="CheckSumKey" value="<secretkey>"/>';
echo '<input type="hidden" name="CheckSum" value="'.$checksum_value.'"/>';
echo '<input type="hidden" name="msg" value="'.$str.'" />';
echo '</form>';

echo '<script>document.getElementById("billdesk_payment_form").submit();</script>';
?>

I have referenced the BillDesk docs and I am not getting exactly what changes I have to do.

Thank you in advance.
