1. If you place the order via PayPal (make the payment)

Go to System > Configuration > Payment Methods > PayPal [...] > Advanced Settings > Debug Mode > Yes

If Debug is enabled you'll find the request/response in var/log/payment_[method name].log

2. If you only get forwarded to Paypal and want to look into the request data (did not finish payment)

Go to Mage_Paypal_Model_Api_Nvp and edit public function call($methodName, array $request)

Add some logging code like


You'll find the file in var/log
