API management refers to the practice of overseeing API-related tasks like developing, publishing, securing, and monitoring APIs. The top and best API management tools have a high level of security, rigorous testing, frequent version updates, and a high degree of stability, which are essential for their optimal use. However, in the process of developing and releasing free online API management tools, usage guidelines are enforced, access is restricted, the subscriber community is fostered, usage data is gathered and analyzed, and performance is reported. Web mechanisms and tools are provided by API Management components to help the developer and subscriber communities. Open-source API management tools will be discussed in this article.

API Management Tools Overview

The many API management solutions on the market assist businesses in making the most of their API integrations, with each offering particular advantages for developing, testing, and maintaining APIs:

  • JMeter

JMeter is an open source program that was first created for testing web applications and is a product of the Apache Software Foundation (the link is external to IBM).JMeter loads and monitors RESTful APIs. MongoDB, Express, and Node.js are their main components.

  • SoapUI

Another cross-platform API testing tool created to automate regression, compliance, and load testing of web APIs is SoapUI (link lies outside IBM). Developers may easily configure their scripts when working in a variety of settings, such as QA, development, and production environments, thanks to SoapUI’s user-friendly testing interface, which enables developers to drag and drop their scripts. Developers may check their APIs for the most recent security flaws, such as SQL injections, cross-site scripting, and XML bombs, using SoapUI.

  • Monitor & Test API Connect

API Connect Test & Monitor was built by IBM. It Connect Test & Monitor lets developers test API endpoints using OAuth and other authentication methods. API Connect Test & Monitor has advantages over other API testing and monitoring packages since it automates laborious tasks. These include collaborative testing models, intelligent API accuracy checking, automated test scheduling, codeless interfaces, and API health notifications.

What Is an API Management Tool? 

An API management tool is a technology used by developers in a business context to access, distribute, control, and evaluate APIs. Platforms for API administration help enterprises by centralizing control over their API integrations and ensuring that they always adhere to strict performance and security guidelines.

API Management Components

API management solutions come with a set of end-to-end services that make it easier to deploy API integrations and share their configurations with other development teams. The following elements make up API management solutions:

  • An API gateway acts as the access point to other linked systems and services. Its gateways route composes and translates client and external protocol requests. API gateways ensure API security by employing TLS encryption and OAuth (Open Authorization) protocols. API gateway lets developers use microservices as controlled APIs.
  • API developer portal: An API developer portal has several uses, but its main advantage is that it gives developers a place to view and distribute API documentation on their own. Developer portals enable developers to quickly explore, create, and test their APIs while also facilitating communication across teams.
  • Reporting and analytics: The ability for companies to measure user numbers in various ways is another crucial feature of API management tools. API platforms employ a synthetic technique to track the availability, response time, and general performance of an API. API systems can also incorporate analytics tools and make use of protocols for data extraction for automated reporting and long-term analysis. These analytics tools help businesses make better decisions about their apps and services by detecting and resolving potential integration problems.
  • API lifecycle management: API integrations are a vital component of strategies for digital transformation and are crucial to assisting businesses in growing their operations. Enterprises gain from API management solutions’ ability to manage an API’s complete lifespan, from conception through all of its development phases and eventual decommissioning. API management offers a long-term approach to developing, testing, onboarding, and administering APIs while providing sufficient version control at each stage.
