Why this program matters

Without Postman mastery, development teams lose an average of 50% of their time on manual API debugging, causing deployment delays of 2 to 4 weeks per sprint.
API errors not caught early cost up to 20 000€ per incident in business losses for e-commerce companies.
In 2026, 85% of DevOps roles require Postman, sidelining untrained candidates and blocking internal promotions.
Every quarter without Postman skills exposes your company to talent loss to more agile competitors.

Program

Module 1Postman Fundamentals: Installation and First API Requests

Quick installation of Postman on your machine, creation of your first professional workspace, sending simple GET/POST requests to public APIs like JSONPlaceholder, exploration of essential HTTP methods, basic OAuth and API key authentication, practical exercises on real enterprise cases with saving reusable collections to immediately boost your API testing productivity.

Module 2Postman Collections: Organization and Dynamic Variables

Structuring Postman collections for scalable projects, defining global and environment variables tailored to your enterprise APIs, managing pre-requests and post-response scripts with simple JavaScript, automated JSON response testing with pm.expect assertions, hands-on practice on a fictional e-commerce REST API, production of your first complete and shareable collection for effective team collaboration.

Module 3Advanced Postman Testing: Scripts and Automated Validations

Developing JavaScript scripts to validate JSON schemas and API performance, using Test Scripts for chaining dependent requests, integrating dynamic data via pm.iterationData for data-driven tests, interactive debugging with the Postman console, exercises on real scenarios like 4xx/5xx error validation, creation of detailed test reports to demonstrate your professional skills at a glance.

Module 4Postman Mocking and Monitoring: Realistic API Simulations

Creating Postman mocks to simulate unavailable or slow APIs, configuring dynamic responses based on custom rules, real-time monitoring with Postman Monitors to alert on API downtimes, integration with Slack or email for proactive notifications, practical cases on your enterprise red thread project, generation of persistent mock servers to accelerate development cycles without waiting for backends.

Module 5Postman CI/CD Integration: Newman and Enterprise Automations

Exporting collections to Newman for command-line execution, integration into Jenkins or GitHub Actions pipelines for automated testing, generating HTML/JUnit reports for CI/CD dashboards, optimizing performance with parallel collections, code review on your final Postman project, deployment of a production monitor and delivery of a certifying action plan to deploy Postman in your enterprise immediately after the training.

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.
