Spring MVC Application with Paypal Integration

[angad jha]

Hello Guys.

I'm using Payment gateway in our Spring Application.
let you know what I have done.
1: I created two account in https://developer.paypal.com/
2: and then we got two email id *[email protected] and *[email protected]
3: Now for Integration We added paypal configuration in Web.xml like below:
<context-param>
<param-name>posturl</param-name>
<param-value>https://www.sandbox.paypal.com/cgi-bin/webscr</param-value>;
</context-param>

<context-param>
<param-name>cmd</param-name>
<param-value>_donations</param-value>
</context-param>

<context-param>
<param-name>business</param-name>
<param-value>[email protected]</param-value>
</context-param>

<context-param>
<param-name>password</param-name>
<param-value>TL45FT5EQWYGLB</param-value>
</context-param>

<context-param>
<param-name>signature</param-name>
<param-value>AFcWxV21C7fd0v3bYasdadsadORY4DvFa</param-value>
</context-param>

<context-param>
<param-name>returnurl</param-name>
<param-value>http://localhost:8080/paypal/success</param-value>;
</context-param>

<context-param>
<param-name>cancelurl</param-name>
<param-value>http://localhost:8080/paypal/cancel</param-value>;
</context-param>

4: Now I made donation form in JSP page

<form action="${initParam['posturl']}" method="post">
<!-- Saved buttons use the "secure click" command -->
<input type="hidden" name="cmd" value="${initParam['cmd']}"/>
<input type="hidden" name="business" value="${initParam['business']}"/>
<input type="hidden" name="password" value="${initParam['password']}"/>
<input type="hidden" name="cert_id" value="${initParam['signature']}" />
<!-- Saved buttons are identified by their button IDs -->
<input type="hidden" name="amount" value="30"/>
<!-- Saved buttons display an appropriate button image. -->
<input type="hidden" name="cancel_return" value="${initParam['cancelurl']}" />
<input type="hidden" name="return" value="${initParam['returnurl']}" />
<input type="submit" name="Donate" value="Donation" />
</form>

5 : then When I'm donating money after login with palpay then we are getting receipt in Paypal page , but I want my page will directly redirect to my Success page with Transaction value.
but It's not happening like that. Please favour me.

Thanks

I don't think you can disable paypal receipt page but you can definitely get the transaction values and the confirmation the payment was really made.

Here is the process:

When paypal redirect to your success page you read the following values:

String payerId = request.getParameter("PayerID");
		String token = request.getParameter("token");

-Before showing your success page to the user, you connect to paypal in the background and confirm the transaction with them and you will get even more details about the transaction.

-Then you can show the success page to the user.

You can also look at paypal IPN to get asynchronous notification but it is not needed. It just add another layer of robustness.

Just look at the documentation.
