 ** *summ* - payment amount, e.g. 10.22 
 ** *com* - description of this payment 
 ** _example_: 
 <pre> 
 <code class="HTML"> 
 <form method="post" action="http://w.qiwi.ru/setInetBill_utf.do"/> 
 <table> 
	 <tr><td>eCosway Shop ID:</td> 
		 <td><input name="from" type="text" value="2042"/></td> 
	
	 </tr> 
	 <tr><td>eCosway Order ID:</td> 
		 <td><input name="txn_id" type="text" value="test-order-1"/></td>

 # Prepare a <code>servlet</code> or <code>JSP</code> to capture the payment status callback. 
 ## the <code>servlet</code> or <code>JSP</code> must accept this query parameter, *paymentResponse* 
 <pre>String paymentResponse = request.getParameter("paymentResponse");</pre> 
 ## decrypt the parameter using *EncryptAES* utils: 
 <pre> 
 <code class="JAVA"> 
 String decryptedResponse = new EncryptAES().decryptSKey(request.getParameter("paymentResponse")); 
 </code> 
 </pre> 
 ## the decrypted <code>paymentResponse</code> parameter consists of *transaction ID*, *payment result*, and *from who* and delimited by <code>comma</code> 
 <pre> 
 test-order-1,true,qiwi 
 </pre>
