Learning objectives

  • Understand the fundamental principles of REST APIs and their architecture
  • Master essential HTTP methods and status codes
  • Design a simple REST API with resources and endpoints
  • Implement basic endpoints using Express.js
  • Test your APIs with Postman and validate responses
  • Apply initial security best practices

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without mastering REST APIs, 70% of junior developers lose up to 20 hours per project on basic implementation errors like recurring 404 or 500 codes, exposing your applications to critical security vulnerabilities with 40% of API breaches due to poor authentication, delaying product launches by 2-4 weeks and costing an average of 5000€ per incident according to Gartner, while poorly structured APIs cause 60% of microservices integrations to fail, hindering your career and the company's business objectives.

Program

Module 1REST API Fundamentals: Principles, HTTP, and First Structure (Postman, JSON, Express.js)

Discover the basics of REST APIs by exploring key concepts like resources, HTTP verbs, and response statuses; dive into practical exercises with Postman to send your first requests; structure your first API in Node.js with Express.js; create GET and POST endpoints on a concrete product inventory case; leave with a functional prototype and validated JSON schemas to boost your project tomorrow.

Module 2REST API Implementation and Testing: Advanced Endpoints, Security, and Validation (Postman, Middleware)

Move to intensive practice by implementing PUT, DELETE, and basic authentication with middleware; rigorously test your endpoints using automated Postman collections; analyze real-world common errors and fix them live; integrate a simple database like MongoDB for persistent data; produce a complete deliverable: a REST API deployable on Heroku, ready to integrate into your web and mobile applications.

Evaluation method

  • Continuous assessment through practical exercises and individualized feedback
  • Interactive quiz on HTTP and REST concepts
  • Final project: Functional API with test report
  • Qualiopi certificate issued

Learning method

  • Interactive lectures with live demonstrations
  • Pair practical workshops on real code
  • Case studies of company-produced APIs
  • Video recordings of sessions for review

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.
