If you’re planning to upgrade your business technology, this almost certainly means working with an effective API. Either you’re building your own to integrate your on-premises technology, importing a third-party API for added functionalities, or monetizing your current capabilities. Regardless, you may find yourself working with a lot of APIs in the near future. But you may not know what to look for in searching for a high-quality API. In this article, we’ll look at some basic characteristics of a good API to give you a head-start on your API development process.

What Is an API?
An API is an essential tool in today’s business technology. APIs facilitate integration between apps and services regardless of programming language, operating system, or file type. Effective use of APIs can open your business to a new economy of data and microservices. Or it can give you a new revenue stream by exposing your business capabilities. The best APIs have a few traits in common.
How do you choose the correct API for your business?
When you’re looking for an API to power your business, there are a few key characteristics you should look for:
- Ease of use: The best APIs are intuitive and easy to use. They don’t require a lot of training or docs to get started.
- Flexibility: The best APIs can be used in a variety of ways. They’re not limited to a single use case or integration scenario. For example, an API that can be used to build a mobile app, a web application, or an IoT device is more flexible than one that can only be used for a single purpose.
- Reliability: The best APIs are built on stable, reliable platforms that won’t break down when you need them most. You need an API to handle the load and boost in api calls if you expect lots of traffic.
- Security: The best APIs use industry-standard security measures to protect your data and transactions.
How do you create an effective API strategy?
There are a few key steps you can take to ensure your API design and strategy is effective:
- Start with your business goals: What are you trying to achieve with your API? This will help you determine which features and capabilities are most important.
- Identify your audience: Who will be using your public API? This will help you understand what they need and how they want to use it.
- Define your scope: What data or functionality will your API expose? This will help you keep your API focused and avoid feature creep. If you plan to build a web API, which web services do you intend to fulfill.
- Choose the right platform: Which technology platforms will support your API development and operations? This includes an app’s entire ecosystem with both the backend infrastructure and the frontend tools.
- Design for success: How will you design your API to ensure it’s easy to use and scalable? This includes both the API itself and the API documentation.
- Test, test, test: How will you test your API to ensure it meets your quality standards? This includes both functional testing and load testing.
It’s important to remember that an effective API doesn’t happen by accident. It takes careful planning and execution to create an API that is both well-designed and well-supported. By crafting an effective API strategy, you can ensure your API meets your business goals and delivers the right experience to your audience.
Outside-In Strategy
The most important characteristic of your API starts before it’s even built. When planning for your new business strategy and the structure of your API, you want to look at it from an outside-in perspective. This means considering the end-user experience first and planning your technology around it. It is also called a “design first” or “top-down” API strategy.
Steve Jobs once said, “You’ve got to start with the customer experience and work back toward the technology — not the other way around.” Putting the user and their experience first ensures that your API (or any other technology) will be accessible, intuitive, and easily adoptable. There’s no hard playbook for this, but most methods in software development for accomplishing it revolve around the same basic framework:
- A prioritization model for making decisions
- An understanding of your audience and their needs
- A value proposition that fits those needs
If you have trouble getting into your audience’s mind, you could make a user persona or two to help. Once you understand your target audience, it’s time to evaluate your technology and what you can introduce to meet their needs.

User-First Execution
The following traits play into the user experience. When someone works with your finished API, you want to show that you value their time and effort.
Accessibility
Your API needs to be designed so that users want to interact with it. A poorly designed API will turn off your users, but great API design will engage them. An accessible API will be more successful than a complicated one with more features. It is important to remember that several stakeholders within your organization will be “consumers” of your API. Making it easy to access and use is therefore critical to the effectiveness of your API.
Consistency
This is key when working with multiple APIs. Your authentication and security measures must be consistent across all of them. Consistency also matters when users are connected with different devices. Ensuring consistency will mean that your development processes are standardized — reducing the risk associated with the development and deployment of APIs.
Discoverability
You won’t be able to hold your user’s hand through the API, and you shouldn’t have to. An effective API is also discoverable, meaning the user can intuitively learn how to work within it. It’s also essential for programmers to find which of your API offerings they need. An API management platform can help by providing an API catalog that details your organization’s suite of APIs.
Documentation
Your API is only as good as its documentation. This is true whether you open it up to the greater API economy or keep it in-house. One way or another, someone new will need to look at your new API and work with it. You want to ensure it’s documented in a way that follows convention and is easy to understand. Good documentation and tutorials will also help with the discovery mentioned above. Adding resources like a code library, SDK, or an API sandbox will make it easier for developers in software engineering to work with your API and facilitate new innovations.
The importance of testing and monitoring APIs
After you’ve built your API, you can’t just set it and forget it. You need to have a plan for how you will test and monitor it on an ongoing basis. This is important for several reasons:
- You need to ensure that the API is functioning as expected and that there are no errors.
- You need to be able to track usage and performance metrics to optimize the API user experience.
- You need to identify any security vulnerabilities so they can be addressed quickly.
Businesses can use automation tools to help with continuous testing so that teams can focus on building a better API.
