# NF-e 4.00 with authorisation protocol

Source: https://xmlvalid.com/schemas/nfe-4.00-proc

> An authorised NF-e (model 55) with the SEFAZ authorisation protocol, the XML file issuers keep and send to the buyer.

Once the SEFAZ authorises an NF-e, the issuer keeps the signed document together with the authorisation protocol (protNFe) in one nfeProc file. This is the XML a buyer receives and the file most systems export.
The schema is procNFe\_v4.00.xsd of Pacote de Liberação nº 9, unchanged, over the NF-e layout of package 010f, which still defines the nfeProc type.

## Notes

- The NF-e inside is checked against the schema and the SEFAZ authorisation rules that need only the file, as in NF-e 4.00. The protocol is checked for its structure only: whether the SEFAZ really issued it is not checked.
- The example is the NF-e 4.00 example with a placeholder protocol of the homologação environment.
