Demystifying the Role of Product Managers in API Development

Building an API isn’t just about creating a tool—it’s about crafting a platform that excites developers and adds value to businesses. But as a Product Manager (PM), what’s your role in this process? Let’s break it down with a simple analogy.

Think about building a mobile app. You focus on engaging users, keeping them interested, and constantly tweaking the app to make it better. It’s all about experimentation and finding what works best to drive user engagement.

Now, let’s compare this to the API world. APIs aren’t like apps that users can see and interact with directly. They’re more like behind-the-scenes tools that help different platforms communicate with each other. The real value of an API comes from how well it integrates with other products.

Unlike apps, APIs need detailed documentation so developers know how to use them effectively. This documentation must stay up-to-date to ensure smooth integration. Stability is also crucial—constant changes can break existing integrations and erode trust.

Backward compatibility is another key consideration. Once customers integrate with your API, they’re unlikely to switch to a new version unless absolutely necessary. So any changes must be carefully managed to avoid disrupting existing integrations.

Despite these differences, some fundamentals remain universal. Customers expect your product to perform well and be secure. They also want an easy way to report issues and suggest improvements, so continuous feedback is essential.

As a PM, your job is to create value for customers, whether through apps, APIs, or other technologies. While each has its nuances, the goal remains the same: to build products that delight users and drive business success.

Understanding these nuances is crucial for navigating the challenges of API development. By sharing knowledge and investing in product management for APIs, we can unlock their full potential and pave the way for future innovation.
