The 7 Commandments for a Successful API Program

APIs are the backbone of modern business strategies, enabling organizations to accelerate digital transformation and deliver value to customers efficiently. However, despite the critical role APIs play, many companies struggle to harness their full potential. According to Google’s “Digital Crunch Time 2022: State of API and Application” report, only about 20% of companies are realizing the full benefits of their digital transformation efforts, and merely 34% of leaders consider their API programs to be highly mature.

So, what sets successful API programs apart from the rest? It’s not just about following a set of steps but understanding how to implement them effectively. Here are the seven commandments that can guide you toward a successful and high-maturity API program.

1. Know the Real Problem

Every organization is unique, with its own set of challenges and goals. While standard API strategies emphasize implementing API management platforms, governance models, and developer ecosystems, these may not address the core issues hindering your API program’s success.

To truly know your real problem, engage with all stakeholders—developers, API consumers, architects, and quality assurance teams. Conduct surveys and gather feedback to identify pain points. For instance:

• Developers may struggle with outdated tools or excessive boilerplate code.
• Architects might be concerned about technical debt and lack of standards.
• API Consumers could be facing difficulties discovering APIs or dealing with redundant and slow APIs.

By digging deeper into these issues, you can identify underlying problems such as API sprawl, lack of standardization, and insufficient documentation, which can significantly hamper your API program’s maturity.

2. Design an API Ecosystem Upfront by Business Domain

One of the biggest challenges in API management is API sprawl—the uncontrolled proliferation of APIs, leading to redundancy and confusion. To combat this, design your API ecosystem based on your business domains from the outset.

Utilize your organization’s conceptual business model, breaking down capabilities into levels (e.g., Level 1, Level 2, Level 3). Develop data APIs aligned with these business domains, institutionalizing domain-driven design and treating APIs as products. This approach ensures:

• Streamlined data API implementation.
• Reduction in API redundancy.
• Intuitive API endpoints that reflect business logic (e.g., /parties for party APIs, /trades for trade APIs).

By structuring your API ecosystem around business domains, you foster clarity and efficiency, making it easier for developers and consumers to understand and utilize APIs effectively.

3. Prevent Real Problems from the Ground Up

Understanding your real problems is the first step; the next is to prevent them proactively. This involves integrating solutions into your architecture, processes, and tools to address issues such as:

• API Sprawl: Implement consistent API design and development standards. Establish an API implementation framework and promote code reuse.
• API Silo: Enhance API discoverability through a centralized repository and developer portal.
• Lack of Standards: Define and enforce API standards and best practices across the organization.
• Under-Fetching and Over-Fetching: Optimize APIs to fetch the right amount of data, improving performance and reducing redundancy.

To achieve this, invest in technology accelerators and frameworks that automate and standardize API development tasks. For example, create an API scaffolding engine that generates standardized code structures and CI/CD pipelines, incorporating your API standards and implementation frameworks. This not only accelerates development but also ensures consistency and adherence to best practices.

4. Embrace API Democratization

An API that isn’t discoverable might as well not exist. API democratization ensures that every API is accessible, discoverable, and usable by everyone in the organization. Achieve this by:

• Publishing API Documentation: Automate the generation and publication of API documentation to a developer portal as part of your CI/CD pipeline.
• Enabling Self-Service: Allow developers and consumers to search for and try APIs without barriers, reducing dependencies and breaking down silos.
• Standardizing Metadata: Encourage developers to include essential metadata, such as technical details, business context, and operational information, making APIs easier to understand and consume.

By democratizing your APIs, you promote reuse, reduce redundancy, and foster a culture of collaboration and innovation.

5. Implement Federated API Governance

Centralized governance models can become bottlenecks, especially in large organizations with numerous APIs. Instead, adopt a federated, decentralized governance model:

• Appoint API Product Owners: For each business domain, designate subject matter experts as API product owners responsible for overseeing APIs within their domain.
• Establish Governance Communities: Create communities of practice where API product owners collaborate to define standards, review APIs, and ensure compliance.
• Automate Governance Processes: Integrate governance checks into your CI/CD pipeline. For instance, when an API is developed, it enters a pending state until the necessary metadata is provided and approved by the API product owner.

This approach ensures that APIs are developed consistently, adhere to standards, and serve the organization’s broader goals without overwhelming any single team.

6. Build Security and Operational Controls into Your API Architecture

APIs are prime targets for security attacks. Protect your organization by embedding security and operational controls into your API architecture:

• Infrastructure Isolation: Separate API gateways and infrastructure based on API types (e.g., public vs. internal) and environments (e.g., development vs. production).
• Standardize Security Policies: Define and enforce security policies consistently across all APIs, utilizing your API management platform’s capabilities.
• Automate Security Testing: Incorporate security testing into your CI/CD pipeline, running standard tests for vulnerabilities like SQL injection, header attacks, and payload validation.
• Leverage Out-of-the-Box Features: Utilize built-in features of your API management platform for policy enforcement, analytics, and more.

By making security an integral part of your API development lifecycle, you reduce risks and enhance the reliability of your APIs.

7. Cultivate a Culture of Developer Evangelism

Developers are the driving force behind any API program. To ensure widespread adoption and continuous improvement:

• Foster Communities of Practice: Create forums where developers collaborate to define standards, share best practices, and discuss anti-patterns.
• Encourage Ownership: Involve developers in the decision-making process, empowering them to take ownership of the API program’s success.
• Promote Knowledge Sharing: Encourage developers to write blogs, host tech talks, and participate in office hours to disseminate knowledge and assist others.
• Recognize and Reward Contributions: Acknowledge the efforts of developers who contribute significantly to the API program, reinforcing positive behaviors.

By building a strong developer community, you create ambassadors for your API program who can drive adoption, innovation, and continuous improvement throughout the organization.

Implementing these seven commandments requires dedication, collaboration, and strategic investment. However, the rewards are significant: a mature, efficient, and effective API program that accelerates digital transformation, fosters innovation, and delivers tangible business value.

By knowing your real problems, designing your API ecosystem thoughtfully, preventing issues proactively, democratizing access, implementing federated governance, embedding security, and cultivating a supportive developer culture, you position your organization to be among the elite few that truly harness the power of APIs.
