Are you calling DoExpressCheckoutPayment, and are you pointing to the Live API endpoint(s)?
(https://api-3t.paypal.com/nvp instead of https://api-3t.sandbox.paypal.com/nvp).
Since you mention “The PayPal service responds Success” I assume you’re looking at ACK=Success. This is merely an acknowledgement that the API call was processed successfully; for the transaction state I’d recommend looking at PAYMENTSTATUS=Completed. This is returned in the DoExpressCheckoutPayment API response.
