http://192.168.2.68/qiwi-provider/sample_payment_form.html

Steps-By-Steps¶

1. First, study the Payment Flow
2. To redirect the customer to QIWI, prepare the following HTML form:
   • action - must be http://w.qiwi.ru/setInetBill_utf.do
   • from - merchant ID
   • txn_id - unique transaction ID, e.g. order ID
   • to - customer's MSISDN, e.g. mobile phone number
   • summ - payment amount, e.g. 10.22
   • com - description of this payment
   • example:
     

     <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>
     
         </tr>
         <tr><td>Customer Mobile No.:</td>
             <td><input name="to" type="text" value="9161234567"/></td>
     
         </tr>
         <tr><td>Payment Amount (RUB a.k.a Rouble):</td>
             <td><input name="summ" type="text" value="2.15"/></td>
     
         </tr>
         <tr><td>Payment Description:</td>
             <td><input name="com" type="text" value="For registration fee"/></td>
     
         </tr>
         <tr>
             <td><input type="submit" value="Pay Now"/>
             </td>
     
         </tr>
     </table>
     </form>
     
     

3. Prepare a servlet or JSP to capture the payment status callback.
   1. the servlet or JSP must accept this query parameter, paymentResponse
      

      String paymentResponse = request.getParameter("paymentResponse");

   2. decrypt the parameter using EncryptAES utils:
      

      String decryptedResponse = new EncryptAES().decryptSKey(request.getParameter("paymentResponse"));
      
      

   3. the decrypted paymentResponse parameter consists of transaction ID, payment result, and from who and delimited by comma
      

      test-order-1,true,qiwi
      

   4. Important Note: This is your responsibility to persist this payment result into the respective interface table.
4. done.
