Hello, I’ve been doing a lot of research, but I haven’t found any documentation, I would like to know how to download the data from an electronic invoice (customer and product list) of the state of Rio Grande do Sul (apparently each state has its own system), from the bar code. I have an application that already reads the barcode, but returns a link to an interface page. From what I read, I should use a Sefaz api, but the urls and parameters I should send are not specified anywhere I found. Would anyone know how to do this or where to find this information?
What is the degree of your doubt ? how to connect ? only the addresses of the services ? is easier to know what to answer, otherwise it is too wide
