Webservice

Webservice


I would like to know if it is possible to use webservice? Is that in order to generate the invoice number, the number will be given to me by the supervisory government through webservice, I can not generate the correlative. Once it generates the correlative the inspection government will register the products of the invoice which will have to send them via webservice as well, it means that I receive and I just receive the invoice to create the invoice automatically. Has anyone done anything like this? Thank you very much.
