Negative Line items are the way to do it https://developer.paypal.com/docs/classic/api/merchant/SetExpressCheckout_API_Operation_NVP/
For a new integration using Express Checkout, I would advise using https://github.com/paypal/PayPal-PHP-SDK and the PayPal payments option.
I don't see any way to declare coupon or discount value for express checkout other than adding a item line with negative value or i missed something?
