This day deepens complex schemas, example management, and security flows. Learners design robust API contracts, use automated linting tools, and deliver an enriched specification ready for integration in a professional context.

Module 3Theme: OpenAPI 3.1 Generation and Testing (Codegen, Mocks, CI Integration) (OpenAPI Generator, Prism, GitLab Pipelines)

Trainees generate SDKs and mock servers, configure contract tests, and integrate the specification into CI/CD pipelines. They produce executable deliverables and measure the impact on backend team productivity.

Module 4Theme: OpenAPI 3.1 Governance (Style Guides, Versioning, Publication) (Spectral, API Portal, Enterprise Strategy)

The final day covers style guides, semantic versioning, and centralized publication. Participants define complete API governance, deploy a documentation portal, and finalize a certifying project for their company.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
