Every invoice in Brazil's economy runs on SOAP 1.2. We mapped it all

This article highlights a practical integration asset for companies operating in Brazil: a complete, production-tested Postman catalog of SEFAZ webservices for NF-e, NFC-e, CT-e, and MDF-e, including SOAP 1.2, mTLS, and e-CNPJ requirements. For CIOs and technology leaders, the strategic value is reducing the complexity, risk, and time-to-integrate around mission-critical tax and logistics document flows that are tightly coupled to revenue recognition, compliance, and business continuity. IT organizations should note the operational nuances called out in the mapping—such as differing SOAP envelopes, regional endpoints, and signing requirements—because these details can materially affect implementation quality, support burden, and audit readiness.
