Learning objectives

  • Master the design of checkout sessions through professional API design for secure flows
  • Develop advanced skills in OpenAPI and Swagger for specifying payment endpoints
  • Implement robust webhooks to manage real-time checkout notifications
  • Optimize checkout sessions to reduce cart abandonment in business settings
  • Design certifying payment APIs compliant with PCI-DSS standards

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1API Design: Designing Secure Checkout Sessions (OpenAPI, Swagger UI)

Discover advanced principles of API design applied to checkout sessions, modeling OpenAPI schemas to define endpoints for creation, validation, and payment management. Practice with Swagger Editor to generate interactive documentation, test complete flows via Postman, analyze real e-commerce cases like Stripe Checkout, and produce a deliverable OpenAPI specification for your company, strengthening your professional skills in certifying API development.

Module 2Checkout Sessions: Implementation and Integration (Node.js, Webhooks)

Dive into the practical implementation of checkout sessions with APIs like Stripe or Adyen, configure dynamic sessions with custom metadata, manage redirections and asynchronous payments via secure webhooks. Practice coding exercises in Node.js to validate HMAC signatures, integrate retry and idempotency workflows, simulate real error scenarios, and deploy a functional prototype, acquiring certifying skills to optimize payment flows in business.

Module 3Optimizing Checkout Sessions: Security, Scalability, and Monitoring (Advanced Webhooks)

Optimize your checkout sessions for maximum scalability, implement fanout webhooks to notify multiple services, strengthen security with tokenization and 3D Secure 2.0, monitor performance via Prometheus and Grafana, test resilience with Chaos Engineering, analyze cart abandonment metrics, and finalize a cloud-ready deployment plan, consolidating your expertise in professional training for performant and compliant payment APIs.

Evaluation method

  • Advanced technical quiz on API design and webhooks
  • Practical project: complete implementation of a checkout session
  • Company case study with oral presentation and OpenAPI deliverable

Learning method

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.
