APIs have become essential for companies that want to give internal and third-party users access to their databases without compromising security. Some APIs clearly work better than others, though. Help your business stand out by following these five ways to optimize your API.

Use Server-Side Script to Add Business Logic

You may have heard that all the code people write in the future is business logic. That statement came from Werner Vogels, VP and CTO of Amazon, during his AWS re:invent 2017’s keynote address. Plenty of technology professionals questioned this idea in 2017. By 2021, viewing code as business logic has started to look like an increasingly useful perspective.

Server-side scripting with Node.js gives your business opportunities to add more business logic to your APIs. DreamFactory supports Node.js, PHP, Python and V8JS so you can create custom logic that meets client needs. You can even configure your API script to call other APIs. From the user’s perspective, everything happens seamlessly. They get the data they need without going through multiple steps that could frustrate them.

Taking advantage of server-side scripting that integrates business logic into your APIs requires some technical skills. You can learn more about taking the right steps by reading the Guide to Integrating Business Logic Into Your DreamFactory APIs.

Adopt Multiple Approaches to Security

Since APIs can give outside users access to your data, it makes sense to worry about the security of SOAP and REST APIs. Ensuring security is one of the best ways to improve your API. Luckily, you have plenty of options that put you in control. DreamFactory makes it easy for you to add security features, including: Depending on your needs, you can use DreamFactory for:

  • SSO authentication
  • JSON web tokens
  • User management
  • OAuth
  • Role-based access control
  • Record-level permissions

Adding these security measures manually can take a lot of time and patience. The right platform lets you add the security measures you need within seconds. 

Break Monolithic APIs by Adding Microservices

When any piece of technology gets too big, it can become cumbersome to use. If you have a monolithic API, you will eventually find it challenging to manage. Tasks can get lost in the queue, limits become impossible to manage and you acquire so many users that you lose control of their access permissions. Take some of the burden off of your API so it can operate more efficiently without opening doors to security issues.

Adding microservices to your tech ecosystem can make your APIs much easier to manage while improving their functionality. Technically, adding microservices to your ecosystem doesn’t change your APIs. It does, however, give your APIs more opportunities to work the way you intended instead of letting a monolithic API get overloaded with constant requests.

Manage Functionality and Security With API Limits

You might assume that rate limits will hinder your API’s functionality by capping the number of requests a user can make. In reality, setting API rate limits helps your API work more efficiently for the vast majority of its users.

When you set API limits, you prevent a single user from dominating access to your API. Once users reach their cap, they need to wait before they can place more requests. This makes it easier for other users to request the data they need. Plus, they will get results faster from a limited API than one that has been overburdened by one user’s huge number of requests.

In some cases, API limits can even improve security by preventing denial-of-service (DoS) attacks that prevent scaling and the average user’s experience.  Many businesses forget about the importance of API limiting.

Try Different Parameters With Live Documentation

Your API documentation defines how your users use your API – and whether they can do so successfully. Live documentation lets you try different parameters so you can determine how your API should process requests and responses. It often helps to try several options so you know that you have chosen one that works well for your intended users.

Swagger UI is one of the most popular tools for interactive live API documentation. You can also use Swagger to auto-generate OpenAPI Specification (OAS) definitions. That way, you can get a good result without spending a lot of time testing parameters that will not work as expected.
