What is an API?

An application programming interface (API) is a collection of software development tools, subroutine definitions, and communication protocols. It is, in general, a set of well-defined communication ways between diverse components. A good API simplifies the development of a computer program by giving all of the necessary building components, which the programmer then assembles.

In simple terms, an API can be for a web-based system, operating system, database system, computer hardware, or software library.

APIs aren't just limited to web services. Operating system calls, database system interactions, hardware signals, and software libraries are all fall into APIs because they all have a well-defined, well-understood interface and protocol set.

Things to Look for When Choosing an API Monitoring Tool

Before you choose an API monitoring tool, it's crucial to understand the elements that go into making that decision. This list will assist you in organizing your selection criteria and making the best decision for your specific application.

  • User-friendly
    When you're monitoring hundreds of APIs, you have to think about how easy it is to use. To test a single API, write multiple different request payloads and repeat the process for the others. Managing all of those numerous testing situations can be difficult if your tool isn't user-friendly.
  • Price
    There is a cost associated with the best tools available. You must examine the price tag and discuss it with your team in order to get an agreement on the pricing. Don't pay the bill right away because some tools have a trial period. Make use of it.

  • Monitoring Dashboard
    You'll want to verify the monitoring status and take action as soon as the tool discovers an issue. Monitoring productivity and visibility will increase if a monitoring tool gives an intuitive dashboard where you can monitor many APIs. You'll want to get alerts sent to your email or phone in addition to the visual support.
  • Scalability
    Scalability is a must-have when you have to monitor tens or hundreds of APIs with the potential to grow. Ease of use and scalability may not always go hand in hand. Before making a final decision, take some time to see if you can grow with the tool you've chosen.
  • Team Collaboration
    You're probably not alone in your team, and you'll want to share a monitoring tool update with your colleagues. A monitoring tool must be able to support a collaborative environment that includes good account management and shared workspaces. You can use this tool to keep track of modifications made by colleagues and add comments to their work.
  • Security
    You might want to interface with the APIs that handle essential processes and sensitive data using your monitoring tool. This is why security is so crucial because you don't want your APIs to be exposed to unauthorized third parties. You should not enable abnormal requests to hit your APIs for testing, in addition to access control.
  • Integration
    A tool that is isolated from the rest of the world will not be able to thrive. Companies already have their own IT resources, and when they select a new tool, they want it to work seamlessly with their existing systems. Make sure to check if an API monitoring tool can communicate with your core resources before deciding on one.
  • Community Support
    When selecting a monitoring tool for your company, you may not want to be an early adopter. It's difficult to locate beneficial advice and information on the Internet when a tool is a brand new to the market. In most cases, a lack of community support translates to a lower-quality product. Always check to see how extensively a tool is used and whether there are any readily available tips.

Postman is one of the most widely used API monitoring tools. It comes with a few options for running and monitoring API tests. You can use Newman or the Collection Runner to test API calls locally. Most clients, on the other hand, are likely to prefer utilizing a Postman monitor. This uses Postman's cloud to execute the API collection.

Each monitoring instance (probably for each API) is referred to as a monitor by Postman. Postman monitors can only connect to endpoints that are publicly accessible. You can run collections in the cloud, view, and plan API requests per collection if you have access to the Postman cloud. The results may then be filtered and graphs showing response time for each test can be viewed.

The ability to create a compilation of integration tests is perhaps the tool's most significant feature. Postman provides access to the command-line tool, the Postman API, the API Network, and integrations.
