How a Service Catalog Empowers API Product Owners to Maximize Value

A few years ago, the term API Product Owner wasn’t widely recognized, but hearing it for the first time signaled a fundamental shift in how companies approach APIs. Today, organizations are treating APIs as full-fledged products, not just technical byproducts of applications. Managing these APIs effectively often involves leveraging a service catalog to ensure they remain organized, discoverable, and valuable.

Think about the early days of your organization’s API journey. APIs were often considered a supporting element of an application—created to enable functionality but quickly forgotten once the application was live. Over time, these neglected APIs became liabilities: outdated, duplicated, and difficult to maintain.

Thankfully, this mindset has changed. Companies now recognize that APIs are cornerstones of their digital ecosystems. As API ecosystems grow in size and complexity, managing them effectively has become one of the greatest challenges—and opportunities—for API Product Owners.

Just like applications, APIs have their own lifecycle. From initial design and development to deployment, maintenance, and eventual retirement, APIs require thoughtful management at every stage. This is where API Product Owners come in, steering the lifecycle and strategy to ensure APIs deliver value to both the business and its users.

Benefits of a Service Catalog for API Product Owners

One of the most valuable tools in an API Product Owner’s arsenal is the Service Catalog. This central resource helps teams streamline API management, enhance discovery, and guide APIs throughout their lifecycle. Let’s dive into how a Service Catalog can empower API Product Owners and their teams:

1. Centralized Discovery- A Service Catalog serves as a single source of truth for APIs within an organization. It enables teams to quickly find and understand existing APIs, reducing duplication and improving collaboration across departments.
2. Governance and Compliance- With APIs scattered across various teams, maintaining governance can be daunting. A service catalog helps enforce standards by providing visibility into each API's status, owner and compliance with organizational policies.
3. Streamlined Lifecycle Management- APIs, like products, require active management throughout their API lifecycle. A Service Catalog can track key metadata—such as API versioning, deprecation timelines, and usage metrics—ensuring APIs remain effective and aligned with business goals.
4. Enhanced Developer Experience- By making APIs easy to discover and understand, a Service Catalog boosts productivity for both your internal and external developers. Clear documentation, consistent standards, and a structured directory make it easier to integrate with APIs and reduce onboarding time. Happier developers = a quicker time to market and better quality products (your APIs), so wherever you can smooth out friction points for them, the better.
5. Driving API Strategy- Beyond operational benefits, a Service Catalog helps API Product Owners take a strategic and proactive approach. By providing a holistic view of the API portfolio, it highlights opportunities for optimization, innovation, and new business models. As an API Product Owner, often your main goal is to deliver the maximum amount of value by ensuring your team’s API meets all business objectives and stakeholder needs–meaning you need that visibility of your entire API portfolio to make key decisions to propel your API strategy in the best direction.

Potential Downsides and Alternatives to Using a Service Catalog

While service catalogs offer significant benefits, it might not be for everyone. Maintaining an API Service Catalog can be resource-intensive. It requires ongoing updates to ensure accuracy, relevance, and alignment with evolving APIs, which can strain smaller teams.

If you’re not using a service catalog, you could explore decentralized approaches, such as team-specific API registries, or adopting lightweight solutions like API portals or wikis, which might be easier to set up and maintain. However, note that these alternatives then sacrifice the centralized governance and standardization that a dedicated service catalog offers (which is a big no-no in the API Product Owner space). Also, lighter-weight options pose a threat of fragmentation and inefficiency down the line as your API team scales.

Ultimately, service catalogs remain the best option for API Product Owners seeking to scale effectively, ensure consistent quality, and provide a single source of truth for APIs that fosters collaboration and innovation across teams and stakeholders.

As the role of APIs continues to expand, tools like the Service Catalog will play a critical role in empowering API Product Owners to meet the challenges of the modern API ecosystem and act as your single source of truth. By treating APIs as products and leveraging tools designed for their unique needs, organizations can unlock the full potential of their API strategy. Product owners can use tools like Blackbird to host their API Service Catalogs.
