Every invoice in Brazil's economy runs on SOAP 1.2
summary
Integrating with SEFAZ webservices for electronic fiscal documents is difficult because the required information is scattered across various manuals and portals. This repository provides a pre-configured Postman collection with ready-made SOAP 1.2 envelopes and variables to streamline the process. By centralizing the technical requirements and providing tested requests, it removes the need for developers to manually scavenge for URLs and envelope structures. The project aims to simplify the issuance and distribution of NF-e, NFC-e, CT-e, and MDF-e documents.
key points
- The collection includes specific configurations for NF-e, NFC-e, and CT-e, handling the a-CNPJ A1 certificate via mTLS and disabling SSL certificate verification to accommodate ICP-Brasil certificates.
- Certain requests requiring XMLDSig signatures cannot be performed directly in Postman, meaning developers must use external signers for authorization and event requests.
- The collection documents critical differences between the various fiscal documents, such as the distinct SOAP body structures for CT-e and MDF-e distributions and the unique GZip+base64 encoding for MDF-e 3.00 authorization.
who should read it

discussion mixed
consensus
Commenters generally agree that while SOAP and XML are outdated and cumbersome, they remain practical for large-scale government and enterprise integrations due to their rigid schemas and maturity. Many argue that replacing these legacy systems is unrealistic given their lifespan and the high cost of migration. However, there is a strong consensus that the primary pain point is not the protocol itself, but poor documentation and inconsistent implementations by different agencies.
top insight
The most valuable perspective comes from the user describing Brazil's e-invoicing system, revealing that the real-world challenge is the gap between official documentation and actual server behavior. They highlight that critical details are often omitted from manuals, and different services may implement the same spec incompatibly, necessitating the creation of community-driven Postman collections to ensure successful integration.
