This is the first post in a series I’m starting about API docs, APIs, and Product. This idea came from my master’s final project (TFM) during my internship at Salsa, where I got to work with talented engineers. I’m excited to share my research in a more engaging way than just reading a thesis. Plus, writing this will help me improve my skills and keep learning more about the tech world. Stay tuned for more posts!

API Docs & API Economy

APIs have revolutionized the way we build software. By enabling the shift from clunky monolithic apps to sleek cloud-based microservices, they’ve opened the door to a whole new world of agility and innovation. The “API economy,” where companies are no longer just creating products for users but are also building for other companies. These businesses play two roles: API consumers and API producers.

The goal? Build faster, innovate smarter, and deliver value with fewer resources.

The Secret Sauce of API Success: Documentation

Imagine companies like Stripe, Twilio, or Salsa—big players in the digital infrastructure game. They’ve embraced APIs not just as tools but as the very foundation of their products. APIs have become building blocks, empowering developers to create faster, more efficiently, and with fewer resources. But there’s a twist:

APIs are not just for tech experts anymore; they are now important for businesses. In this new world, the key to success is definitely good documentation.

Yes, you read that right. Documentation isn’t just a sidekick—it’s the hero of the story. A well-crafted API doc isn’t just a user manual; it’s a deal closer.

Here’s the truth:

• Bad documentation = Frustration 😡
• Good documentation = Trust 🛠️

Bad documentation is like a GPS with missing streets—it’s frustrating and makes people turn back. Good documentation, on the other hand, can win over even the most skeptical developers. It builds trust, simplifies integration, and makes your product stand out in an increasingly crowded market.

What Developers Want (and Why Your Docs Might Be Failing)

Developers are busy, so your documentation needs to work for them. This means:

• A developer portal that’s easy to navigate.
• A sandbox environment for testing APIs directly in the browser.
• Real-world examples that show how to solve common problems.

🚨🚨 Why? Because developers—your new customers—rely on it to understand, evaluate, and ultimately decide whether your product is worth integrating.🚨🚨

But what does great API documentation actually look like? (I’ll dive deeper into that in my next post!)

Docs: A Living Part of Your Software Lifecycle

Good documentation isn’t static. It needs to evolve with your product, integrating seamlessly into modern software practices like:

• Code reviews to keep examples accurate.
• Version control for tracking changes.
• CI/CD pipelines to ensure updates are delivered in real-time.

By treating documentation as part of the development lifecycle, you’re not just helping developers—you’re creating a better product experience for everyone.

Great documentation doesn’t just happen.

Why This Matters More Than Ever

In the API economy, your competition isn’t just about features or pricing—it’s about the experience you deliver. If your documentation makes life easier for developers, they’ll be more likely to adopt your API, recommend it to others, and build amazing things with it.

On the flip side, poor documentation can ruin even the best product. Don’t let that happen.

Final Thoughts

If your business depends on APIs, it’s time to give your docs the attention they deserve. Make them clear. Make them useful. Make them part of your process.

Because in today’s world, great docs aren’t optional—they’re your competitive advantage.
