# NF-e Issuance Scenario

According to FISCO requirements, communication with the government must take place through an XML file with information about the issuer, recipient, products, taxes, transportation information, payment, etc. This XML document is digitally signed using a digital certificate compliant with ICP-Brasil standards. Having the digital certificate in the A1 standard is essential for this step to be completed. Finally, communication with government servers takes place, using SOAP technology.

As it is an asynchronous transaction, it is necessary to make status verification calls with the government services until a final status of the NF-e (authorized, rejected, or denied) is obtained. In the case of rejected notes, the reason may be technical or business rules and must be corrected before a new submission.
