Learning objectives

  • Design scalable REST architectures and microservices
  • Implement advanced OAuth2 and JWT authentication
  • Optimize performance with caching and pagination
  • Secure against SQL injections and DDoS attacks
  • Exhaustively test with Postman and Jest
  • Deploy on AWS or Docker in production
  • Document via Swagger and OpenAPI

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 advanced REST API mastery, 70% of APIs remain vulnerable to breaches (source OWASP), exposing customer data to costly leaks averaging 4M€ (IBM).

  • Degraded performance hampers 40% of web apps, generating revenue losses up to 25%.

  • Developing without scaling?

  • Cap growth at 10k users.

  • Obsolete architectures lead to forced refactoring, +200h lost.

  • Invest 35h to avoid these pitfalls, secure your revenue and reputation today.

Program

Module 1REST Architecture: Modeling Scalable APIs (HATEOAS, versioning)

Dive into designing advanced REST APIs, model resources with UML, apply HATEOAS for hypermedia, version endpoints via URL or headers, complete exercises on real e-commerce cases, produce implementation-ready deliverable schemas, everything to build robust APIs that evolve without breaking clients.

Module 2Advanced Implementation: Handlers, Middlewares (Node.js/Express)

Code complex endpoints with Express or Spring Boot, integrate middlewares for logging and validation, handle HTTP 4xx/5xx errors with structured responses, simulate business flows via hands-on workshops, generate functional source code, test live for immediate mastery of professional REST patterns.

Module 3REST Security: OAuth2, JWT, Rate Limiting

Strengthen your APIs against threats, implement OAuth2 flows with Keycloak, sign JWT tokens, configure CORS and rate limiting via Redis, analyze OWASP Top 10 attacks on real cases, produce secure configurations ready for deployment, gain peace of mind with impenetrable APIs.

Module 4Performance and Scaling: Caching, Pagination, Async

Boost your APIs with Redis caching, offset/limit/cursor pagination, async management via Promises or RxJS, profile bottlenecks with tools like Artillery, optimize NoSQL database queries, run live benchmarks, deliver ultra-responsive APIs scalable to 10k req/s.

Module 5Testing, Deployment, Documentation (Postman, Docker, Swagger)

Test end-to-end with Postman collections and Newman CI, containerize with Docker Compose, deploy on Kubernetes or Heroku, generate interactive Swagger UI docs, integrate CI/CD with GitHub Actions, finalize personal capstone project, leave with production-ready API portfolio.

Methods, materials and delivery

The Advanced REST API Training - Secure and Scalable APIs program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Advanced REST API Training - Secure and Scalable APIs program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Advanced REST API Training - Secure and Scalable APIs program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

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.
