I need to get information from a company through the CNPJ, however, when searching the internet, I realized that there are several web services of the sefaz, each one facing the Brazilian state.
In this way, if the webservice is from RIO I can not retrieve information from a CNPJ from São Paulo.
I learned that there is a 'universal' web-service and I would like to find it ... can you tell me where I find this blessed? otherwise the program would be prone to crashes, as I would be required to work with a webservice for each state.
