Money Transfer

When transferring money, our server requests four parameters. This variable is Receiver Account Number User Account Number Pin Number Transfer Amount

• Money Transfer Request Look Like This:

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://localhost/SP/server.php">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:transfer_money soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <details xsi:type="ser:Bookcatalog.Transfer">
            <!--You may enter the following 4 items in any order-->
            <account_number xsi:type="xsd:int">1</account_number>
            <money_amount xsi:type="xsd:int">20000</money_amount>
            <pin xsi:type="xsd:string">12345</pin>
            <to xsi:type="xsd:int">4</to>
         </details>
      </ser:transfer_money>
   </soapenv:Body>
</soapenv:Envelope>

• Request Look like this:

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost/SP/server.php" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>
      <ns1:transfer_moneyResponse>
         <return xsi:type="xsd:string">Money Transfer To Finished, Current Account Balance Is : 27000</return>
      </ns1:transfer_moneyResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

• Before transferring money, the server verifies three logics. The user's account number and pin must be entered correctly, and the revisionist's account number must already exist in the bank. DB. The conclusion is that the account balance cannot be insufficient. The system's response will appear as follows when the user enters the wrong user account number and pin.

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost/SP/server.php" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>
      <ns1:transfer_moneyResponse>
         <return xsi:type="xsd:string">Wrong Pin Number Please Double Check Pin Number</return>
      </ns1:transfer_moneyResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

• If an account has insufficient funds, the system will respond as follows:

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost/SP/server.php" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>
      <ns1:transfer_moneyResponse>
         <return xsi:type="xsd:string">Insufficient Account Balance For Money Transfer</return>
      </ns1:transfer_moneyResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
