The Complete Practical Course on API Strategy, Design, and PRDs
Learn to design, spec, launch, and govern APIs. A practical course for PMs covering contracts, versioning, security, monetization, and a capstone API PRD.
The API Is a Contract, Not a Technology
Why "I'm Not Technical" Is the Most Expensive Sentence in Product
The Three APIs You Will Actually Encounter: Internal, Partner, Public
Anatomy of a Request and a Response
Where PMs Actually Sit in the API Lifecycle
This module builds the mental model everything else in the course depends on — what an API is, why it functions as a contract between systems, and where product managers actually create value across its lifecycle.
HTTP Methods and Status Codes: The Vocabulary You Need
Authentication and Authorization, Explained Without Jargon
Rate Limits, Pagination, and Idempotency — Why These Words Cost You Money
Reading an API Spec (OpenAPI/Swagger) Without Panicking
The technical vocabulary needed to sit in any engineering discussion and ask a real question instead of a vague one, without becoming an engineer yourself.
Designing the Developer Experience (DX)
Versioning and Backward Compatibility: The Promise You Cannot Break
Writing API Documentation Developers Actually Use
REST vs. GraphQL vs. Webhooks: A Data-and-Use-Case Framework
How to treat API design as a product discipline — covering developer experience, the versioning promises you can never break, documentation that developers actually use, and choosing between REST, GraphQL, and webhooks.
Deciding What API to Build (and What Not To)
Writing an API PRD That Engineers Can Build From
Running an API Design Review
Beta, GA, Deprecation, and Sunset: Managing an API's Whole Life
How to manage an API across its full lifecycle — deciding what's worth building, writing a PRD engineers can build from, running a design review, and managing beta through deprecation and sunset.
Monetizing APIs: Four Models and When Each Works
Platform Strategy: Becoming the API Your Ecosystem Builds On
API Security and Privacy, in Plain English
Vocabulary Fluency: Fifteen Terms That Change How Engineers Treat You
How to think about APIs at the business level — monetization models, platform strategy, security and privacy fundamentals, and the vocabulary that changes how engineers treat you.

No. The course is built for PMs, APMs, and founders with zero technical background. It focuses on the product judgment behind API decisions, what to expose, how to name and shape things, versioning tradeoffs, not on writing code.
Write a real API Product Requirements Doc, run an API design review without embarrassing yourself, and answer API-specific PM interview questions with substance instead of buzzwords.
5 modules and 21 lessons (about 5 hours total), moving from foundations (what an API is) through how APIs work, designing APIs as a product, the API lifecycle, and strategy/security, followed by a capstone PRD and a 25-question interview appendix.
They're three different products with three different quality bars, internal APIs only need to satisfy your own engineering team, partner APIs must survive an outside engineer's first hour unaided, and public APIs must survive thousands of strangers, forever, with a formal deprecation policy for changes
Anything that could cause an existing, correctly-written integration to fail, including things that feel harmless, like changing a default behavior or a field's format, even if you didn't remove or rename anything.
Yes, Module 3 gives a decision framework based on the shape of the caller's need (fetch a thing, fetch a flexible slice of nested data, or get notified the moment something happens) rather than treating them as competing philosophies.
Yes, the capstone has you write a full 10-section API PRD for a real API, including worked request/response JSON, a versioning policy, and an auth/security review, meant to be ready to hand to an engineering team.
Yes, in Module 5. four monetization models (freemium, usage-based, tiered, revenue share) and what separates building an API as a feature versus building it as a genuine developer platform.
Yes, the appendix has 25 real interview questions organized by course topic, each with notes on what a strong answer actually demonstrates versus a weak one.
No, though it helps, most lessons include a "Your Move This Week" exercise you can apply to any API your product exposes or consumes, even one you don't directly own yet.
