What you'll learn

Collect & Organize Developers' API Requirements

We'll take data and ideas collected from existing users and use AI to organize into patterns & use cases you can act on.

Break Down Use Cases into Automation Outcomes

Translate what users' needs into specific API endpoints and payloads they can use, including useful error messages.

Generate an API Design as a Hypothesis

You'll use my prompts to generate a blueprint for an API, using your context and market insights.

Get Ready to Validate the API with Real Users

Once you have a solid design, we show you how to validate it against standards and how to get feedback from your users.

Why this topic matters

A public API turns your product into a platform. It reduces churn as users build your product into their workflows, whether they code, or use tools like Zapier. In 30 minutes, I'll show you how to go from raw user feedback to an API design. We'll come up with an API for Maven students like you as our example. Bring your own use case or follow along. You'll leave with a process you can repeat.

Founder, Level 250 | 3x VP, API Products

I’m Emmanuel, an entrepreneur, product management executive, and consultant at Level 250 with over 15 years of experience shaping API products.

I’ve led large API programs in fintech for Verisk, Moody’s, and Precisely, and served as VP of Product for some of the world’s most influential API tools—like API Blueprint at Apiary (550,000+ APIs), Oracle’s first Cloud-Native API Gateway, and Swagger at SmartBear (750,000+ APIs).

Over the years, I’ve consulted with everyone from Fortune 500 CEOs to startup founders, engaging with thousands of API providers and consumers to help them build winning products and exceptional developer experiences.

My passion is to make APIs more impactful and developer-friendly, which is why I created API Fundamentals for Product Managers: to share my lessons learned and help Product Managers fast-track their careers.

Join me to gain practical insights, avoid common pitfalls, and learn how to deliver API Products that enable great user experiences—without repeating the mistakes I’ve already made along the way.
