PayPal

PayPal
PayPal is currently in BETA.
PayPal is a popular eWallet, whereby their users are able to send and receive money using funds directly from their wallet and / or from their credit / debit card. 
Link your existing PayPal account to Judopay, to enable an easy integration of PayPal alongside other payment methods. 
Reconcile your PayPal payments within the Judopay Portal.
﻿
Integrating PayPal (BETA)
Integrate PayPal using our Web SDK.
Contact Developer Support to link your production PayPal account to your Judopay account.
Currently, you are only able to link your production PayPal account.
For more details on testing, contact Developer Support.
Prerequisites
Make sure you are using Web SDK Version 0.0.18 (or higher).
Make sure you have implemented the following prerequisites from the Web SDK integration guide:
﻿Create a paymentSession﻿﻿
﻿Add the Payment Form to your Website﻿﻿
The payment form iFrame must be loaded onto the page in order for payments to work. 
However displaying the form to the consumer is not required for this transaction type.
To hide the payment form iFrame, use: 
<div id="payment-iframe" style="position:absolute;width:0;height:0;border:0;"></div>
﻿
﻿
Step One: Display the PayPal Button
﻿
Currently /payments (immediate capture) is supported when implementing PayPal via the Web SDK.
Make sure the following parameters are the same values as those entered in Creating a paymentSession﻿ otherwise the transaction will fail:
merchantPaymentReference
merchantConsumerReference
JudoID
Currency
Amount
This is used to cross reference the validity of the transaction.
Your backend server should store the paymentSession response reference returned by Judopay's API. 
Use this reference from the response to populate yourPaymentSession.
Make sure you replace the payPalConfiguration object values with your own.
