How can I automatically track PayPal donations and display it on my site?

I would like to automatically track PayPal donations and di开发者_StackOverflowsplay the current donation amount in my site.

So, How can I do it?

Should I use PHP?

Do you know tutorials for it?

Thanks

You might take a look at the Instant Payment Notification system https://cms.paypal.com/cms_content/en_US/files/developer/PP_OrderMgmt_IntegrationGuide.pdf . It would allow you to setup a receiver page that would be notified of each paypal payment.
