Existing website already running Worldpay and Paypal as payment processors needs to upgrade the Paypal installation to Website Payment Pro from Paypal.
This website is run on a custom script, there is no shopping cart software in use. All the payment pages are already in place and working. Only Paypal portion needs to be modified for Paypal Pro.
The website accepts payments in 3 currencies, Dollars, Pounds and Euros. Depending on the location of the shopper, the appropriate payment page is displayed. This functionality is also already in place.
When a shopper makes a payment, the payment processor sends a callback and the database is updated with the payment information. The website involves recurring transactions. So, for Paypal Pro this functionality has to work. Every time there is a renewal, a callback process has to update our database.
There are 4 websites that need to be modified, but they are EXACTLY the same. Once one is done and working it is a simple matter of copying over the changes.
ONLY PROGRAMMERS WITH PAYPAL PRO INTEGRATION EXPERIENCE NEED APPLY.
