The State of API Quality in 2024: Insights for Developers

Introduction


Calling all tech-savvy kids! Have you ever wondered how companies create all the cool apps and websites you use every day? A big part of it has to do with something called "APIs" (which stands for Application Programming Interfaces). APIs are like secret handshakes that allow different software programs to talk to each other and share information. 


However, developing and maintaining high-quality APIs is no easy feat. That's why the team at SmartBear decided to survey over 1,100 API experts from around the world to get the scoop on the current state of the API industry. Their findings, published in the "State of Software Quality API 2024" report, reveal some fascinating insights that can help developers like you create even better APIs in the future.


Let's dive in and explore what this report has to say!


State of API Quality in 2024

The Scope of the API Quality Survey


The "State of Software Quality API 2024" report is based on a survey of more than 1,100 API professionals working in over 17 different industries around the globe. That's a whole lot of people sharing their experiences and expertise!


The goal of the survey was to uncover the latest trends, best practices, and challenges when it comes to designing, testing, and maintaining high-quality APIs. The report covers everything from how APIs are documented and tested to the tools and methodologies used to manage the entire API lifecycle.


This isn't the first time SmartBear has conducted this kind of survey. They've been doing it annually since 2016, although there was a break last year. So the 2024 report marks a return to this important industry analysis, giving us a chance to see how things have changed over time.


API Quality Is a Top Priority


One of the key findings from the report is that API quality and standardization are becoming increasingly important for businesses and developers. As more and more companies rely on APIs to power their applications and connect with their customers, there's a growing focus on ensuring those APIs work smoothly and reliably.


According to the survey, 70% of respondents said that API quality is a top priority for their organization. That's a big jump from previous years, showing that companies are really starting to recognize the critical role APIs play in delivering great products and services.


Part of this shift is driven by consumer expectations. Customers these days expect apps and websites to work seamlessly, with no glitches or frustrating errors. And since APIs are often the backbone of these digital experiences, companies know they need to get API quality right.


So how are they doing it? The report highlights a few common strategies, including:


- Implementing more rigorous testing and quality assurance processes

- Adopting standardized API design and documentation practices

- Using specialized tools and technologies to manage the API lifecycle


Let's take a closer look at some of these trends and best practices.


Designing and Documenting APIs for Quality


One of the keys to building high-quality APIs is getting the design and documentation right from the start. After all, if an API is confusing or hard to use, it's going to be a nightmare for developers to work with.


According to the SmartBear survey, 62% of respondents said they use an API design and documentation tool, like Swagger or Postman. These tools make it easier to create clear, comprehensive API documentation that developers can reference when building their applications.


But it's not just about the documentation - the API design itself is crucial too. Many companies are adopting standardized API design patterns and frameworks, like the OpenAPI Specification, to ensure consistency and usability across their entire API ecosystem.


In fact, the report found that 71% of respondents said they use a standardized API design approach. This helps them create APIs that are more intuitive and easier to integrate, which is a big time-saver for dev teams.


Testing and Monitoring APIs for Quality


Of course, great API design is only half the battle. You also need to thoroughly test your APIs to catch any bugs or performance issues before they reach your customers.


The SmartBear survey revealed that 77% of respondents said they use automated API testing tools to validate their APIs. This includes everything from functional testing to security and load testing. Automated testing helps dev teams save time and catch problems early in the development process.


But testing isn't just a one-time thing - it needs to be an ongoing process. That's why many companies are also investing in API monitoring solutions to track the health and performance of their APIs in production. The report found that 66% of respondents use some form of API monitoring.


By continuously monitoring their APIs, companies can quickly identify and fix any issues that pop up, ensuring a smooth experience for their users.


Managing the API Lifecycle


Creating a high-quality API is just the beginning. Companies also need robust processes and tools to manage the entire API lifecycle, from design and deployment to maintenance and retirement.


The SmartBear survey found that 73% of respondents said they have a formal API management strategy in place. This typically involves using specialized API management platforms to handle tasks like:


- Cataloging and organizing all of a company's APIs

- Enforcing security and access controls

- Analyzing API usage and performance data

- Automating the API release and deployment process


By taking a more structured, strategic approach to API management, companies can ensure their APIs remain reliable, secure, and up-to-date over time.


Industry Trends and Benchmarks


Beyond just the overall focus on API quality, the "State of Software Quality API 2023" report also uncovered some fascinating industry trends and benchmarks.


For example, the survey found that the most common API architectures are REST (used by 82% of respondents) and GraphQL (used by 36%). And when it comes to API versioning, 57% of companies said they use semantic versioning to indicate compatibility changes.


The report also delved into the specific tools and methodologies used by API teams. It found that Agile development (used by 70% of respondents) and DevOps practices (used by 60%) are becoming the norm for managing the API lifecycle.


In terms of testing, unit testing (used by 72% of respondents) and integration testing (used by 65%) are the most widely adopted approaches. This helps ensure that individual API components and their interactions work as expected.


These industry insights can be really valuable for companies looking to benchmark their own API practices and see how they compare to their peers. It can also help guide future investments in API tools, training, and process improvements.


Looking to the Future of API Quality


The "State of Software Quality API 2023" report paints a picture of an API industry that is increasingly focused on quality, standardization, and efficiency. As more and more companies recognize the critical role APIs play in their business success, they're putting a greater emphasis on getting API development right.


This trend is likely to continue in the years ahead, with companies investing even more in automated testing, API monitoring, and lifecycle management tools. They'll also likely double down on standardized design practices and documentation to make their APIs more user-friendly for developers.


At the same time, we may see more innovation in areas like API security, scalability, and edge computing as companies strive to deliver APIs that are fast, reliable, and secure.


So if you're a budding young developer, keep an eye on the API space - it's an exciting and rapidly evolving field that's only going to get more important in the years to come. With the right skills and tools, you could be the one building the next generation of high-quality APIs that power the digital experiences we all love.
