The parameter billnumber can be passed either in ordinary format (when there was only one successful payment on this order) or in extended format in the confirmation. While using the extended format it is required to provide the exact number of the successful authorization operation (in some cases it can be not a first operation in the order, 5111111000965142.2 for example).
