Seppmail-OpenAPI

OpenAPI and Postman-oriented assets for documenting and testing SEPPmail API capabilities.

This repository is maintained in a consistent public format by Synedat Group GmbH for the SEPPmail ecosystem. It is designed to be useful in discovery, implementation, operations, troubleshooting, architecture review and controlled handover scenarios.

What this repository is for

The focus is schema-first thinking, contract review, example generation, linting and API discoverability.

It should help teams move from isolated commands or scripts to a more reviewable and reusable operating baseline.

Intended audience

API designers, integrators, testers and developer enablement teams.

Repository highlights

• production-minded examples instead of bare placeholders
• stronger documentation depth for architecture, permissions and operations
• reusable guidance for evidence capture and change-safe execution
• consistent Synedat references and public discoverability across repositories
• compliance-aware wording for ISO/IEC 27001, BAIT, DORA, TISAX and adjacent governance themes

Main building blocks

• OpenAPI spec
• Postman environment
• Request examples
• Governance and review notes

Quick start

1. Inspect the OpenAPI schema and version metadata.
2. Run a simple curl or Postman request.
3. Add contract review and linting before generating downstream clients.

Typical use cases

• API discovery and onboarding
• Contract review
• Collection building for demos
• Client generation and test harness creation

Permissions approach

• Read-only API access for exploration
• Separate write-capable credential for destructive tests
• Reviewer role for approving collection changes

Security and governance note

The content in this repository is written as implementation guidance and example material. It can support evidence-oriented work for information security and operational resilience, but it does not replace formal policy, legal interpretation, certification scope or vendor support statements.
