Description

---

Every product manager is expected to "understand APIs" - but most PM courses either skip the topic entirely or drown you in engineering jargon that doesn't stick. This course closes that gap.
What you'll learn

---

In this course you'll explore how APIs are built, tested, and used in real products-through clear explanations, hands-on demos, and a real-world case study drawn from a live fintech API. Each section combines conceptual grounding with practical, tool-based exercises to make learning stick.
You'll start with the fundamentals of how APIs work, then dive into the mechanics of
HTTP requests and responses-methods, headers, endpoints, status codes, and error structures
REST API design and how to think in resources, not actions
Authentication - API keys, OAuth, and tokens, and when each is used
Testing anddebugging APIs using a professional API client
Reading realAPI documentation like an engineer would
Real-world APIobjects,resources, andversioning in a production system
Idempotency,pagination, andrate limiting-and why they matter for product decisions
Webhooks andevent-driven architecture, including signature verification and failure handling
You'll also learn how to translate these concepts into sharper specs, better technical conversations, and faster debugging-without ever needing to write code.
What's Inside
4 core modules with 25+ practical lessons
Real API workflows using industry-standard tools and a live production-grade API
Concepts explained with diagrams, analogies, and hands-on exercises
Designed for learners with no prior technical or coding background
Taught by a Product Manager & Instructor with industry experience
By the end of the course, you'll have a practical and complete understanding of APIs-from how they're structured to how they fail and recover. You'll be able to confidently contribute to technical discussions, write better specs, and work alongside engineering teams with real fluency.
