Magento: how to get Paypal transaction ID?

Question

I'm trying to print the Paypal transaction ID on our invoice PDF files. Can you pull this information from $order, which is an instance of Sales_Order?

I did find some database tables with paypal_ prefix, but all of them are empty, even though we have a real Paypal transaction order in our installation. Any ideas?

Answer 1

Try : $transaction_id = $order->getPayment()->getLastTransId();
