Paypal Integration Help Docs

We have to follow the following steps:

1. Define API Information
2. Redirect to Paypal [with some POST value for payment information]
3. Redirect Back to Our Application with an IPN[Instance Payment Notification]
4. Process and handle the payment on our app [validate , store and update the payment information]

 

Here is an Example Form:

<form id="paypal-form" action="https://www.sandbox.paypal.com/cgi-bin/webscr" accept-charset="UTF-8" method="post" >
 

 
 
 
 
 
 
 
 
 
 ">
 
 
 
 
 

 
 </form>
