What are Application Programming Interfaces (APIs)?

“API” is a broad term that encompasses a set of protocols, tools, and routines that allow businesses to harness the power of data.

APIs power most applications used today. This is because they enable developers to include core features of complex websites in the applications. Also, they allow those features to be integrated and used in different ways.

It is essential for businesses because it is through an API that they are able to get different programs to communicate with each other.

Since APIs are growing in popularity, it becomes extremely difficult and complex to manage them. This is where API management comes into the picture. It helps you design, analyze, document, and publish APIs in a secure environment.

It has become so popular that the API management market is expected to reach $3,436.16 million by 2022.

To make the best use of an API, you should document it well and secure it too. You can do this through consistent testing and regular updates. To simplify this process, you can use API management tools.

Why Do You Need API Management Tools?

While API management tools make it easy for your organization to develop, manage, and secure APIs, they offer a lot more than that.

They can also help with API planning and testing stages. This is important because after designing an API, you need to test it to ensure that it works the way you want it to.

Additionally, API management tools also help ensure that the APIs you previously deployed are compatible with the new ones. This can help reduce your app development costs. Finally, they simplify the process of publishing and deploying APIs.

Now, let’s take a look at how you can select the best API management tools for your organization.

How Do You Select the Best API Management Tools For Software Development?

There are a lot of API management tools out there. So, you need to be careful when selecting the one you want to use for developing software solutions.

Here are some factors you should consider while selecting API management tools for your organization.

1. Ease of Use

The first thing you check before selecting API management tools is the ease of operation. If the API management platform you choose isn’t easy to use, your team will find it difficult to manage your APIs.

Additionally, a good API management tool should make it simple for you to manage your developers. Apart from that, it should also integrate well with other infrastructure that you already have in place.

2. Scalability

This is yet another important factor to consider when choosing API management tools. Scalability is a crucial factor for growing your business, and the tools you use must be able to support that development.

It’s due to this reason that you need to check if your tool can support your organization’s growth or not.

Let’s say your software solution powers an ecommerce platform. When you use an API management platform that is scalable, it’ll be easy for you to perform optimally during peak periods (such as Black Friday). Else, your system may crash due to the increased activity.

3. Security

Before choosing an API management tool, you must check if it’s secure to use. You need to verify if it has strong single-sign-on (SSO) capabilities.

Also, it must have policies that make the use of an SSL (Secure Sockets Layer) compulsory. It should also protect you against web-based threats and disable login if a VPN isn’t turned on.

Additionally, it should be GDPR-compliant to foster trust and loyalty with your customers. After all, that can help improve your customer retention.

4. Comprehensiveness

The last factor that you need to consider before choosing an API management tool is its comprehensiveness. You must confirm if the API management platform covers both the API publisher and consumer components.

API publisher components include designing, creating, testing, securing, and managing.

On the other hand, API consumer components include discovering, developing, consuming, and monitoring.

An ideal API management tool should be able to effectively handle most, if not all, of these components.

Now, let’s take a look at the best API management tools and how you can use them effectively.

Q2. How does API management work?

A. API management enables businesses to monitor and control the visibility of APIs connecting data and applications across the cloud or enterprise. It enables them to enforce API usage policies, publish web APIs, nurture subscriber community, collect and analyze statistics on usage, control access, and report on performance.

Q3. Which is the best API testing tool in the market?

A. Some of the best API testing tools include:

  • Katalon
  • RapidAPI
  • Paw
  • Axway
  • Apigee API Management
  • SoapUI
  • Postman

Q4. How do you perform API Testing?

A. Follow these steps when performing API testing:

  • Start by determining test requirements and boundaries. Specify issues like the APIs' purpose, target consumers, API features and functions, testing aspects, etc.
  • Establish a test environment by configuring databases, servers, and all resources interacting with the API.
  • Run a trial call to ensure the API works and has no broken functionalities.
  • Define input parameters. Effectively authenticate results and determine that the API works as you expect by planning possible input combinations.
  • Create test cases. Write, execute, and compare the actual results of the test cases to the expected ones. You can either leverage API testing tools or write code that helps you run the tests. It's, however, recommended that you automate the process.

Q5. Why do you need API management?

A. Reasons why API management is crucial:

  • Insights from API analytics drive data-driven decisions.
