How does API work? Tools for API development

May 14, 2021By Rakshit Patel

Let’s look at an example to better understand how the API works. Assume you’ve gone to the ABC website or downloaded the ABC app to book a flight. You completed the form by entering all of the necessary information, including the departure and return dates, flight numbers, cities, and other relevant information.

As soon as you apply, a list of flights with information such as seat availability, timings, pricing, and other details will appear. But how did it happen in the first place? The APIs are to blame.To provide such precise data, the platform sends a request to the website, which then uses API to access the database and retrieve all relevant data. The data that was distributed via API is then returned to the website.

The API serves as an intermediary in this case, streamlining the data sharing process. The airline website and flight booking portal, on the other hand, serve as endpoints. When it comes to communicating endpoints, APIs function in two different ways: SOAP and REST.

Let’s take a look at the basic terminologies used in API development now that we’ve gotten a better understanding of how APIs function.

Terminologies used in the API development process

API Access Code

It’s a one-of-a-kind code that’s passed between computer programmes to identify the user, creator, or calling programme.


Endpoints are the points of interaction between the server and the API.


JSON (JavaScript Object Notion is a Data Format) is a data format for transferring data between APIs. This data exchange can happen between a web application and a server, or between two apps and the AngularJS Development and ReactJS Development.


GET is a tool for requesting information from a server at a specific resource.


It’s a way to submit data to the API server in order to update or build a resource.


It’s an API authorization system that’s based on an open standard. It provides safe and limited access to end-user data that is to be used by the application or third-party websites without the end-permission. user’s


Rate-limiting is the method of regulating the rate of both incoming and outgoing traffic. It’s also known as the cumulative number of API requests made by a user.

API Throttling

API throttling is a mechanism in which consumers’ access to APIs is limited for a set period of time.

Tools for API development

When it comes to API development, there are numerous tools available. The following are some of the most common tools and products used by API developers:


Google’s Apigee is an API creation management tool. When an organisation is upgrading legacy Mobile App or enabling data sharing between apps and services, this tool comes in handy. Aside from that, it’s also useful when a new product is being developed.


Dredd is a platform for checking HTTP APIs. It’s used in the backend to verify an API’s definition. It also extensively examines the API’s definition and determines whether or not the API has been validated.


APIMatic is a website API developer interface tool. It is used by developers to build SDKs for their APIs on ten different platforms. It’s also used to keep it in line with the rest of the system.Developers may use this tool to translate API descriptions into a variety of formats, including WADL, Swagger, RAML, OAI format, IO Docs, API Blueprint, HAR 1.4, Postman Collections, and others.


Sandbox generates a mock RESTful API from API definitions quickly and easily. It also lowers the risk and cost of calling third-party APIs during testing.

SoapUI is a free and open-source testing application. It is cross-platform compatible. It’s also capable of automating both functional and non-functional checks. Regression, enforcement, execution, security, and load tests are all performed with it.


Swagger is an API development tool that is open-source. Swagger is used by big tech companies like Getty Images, Apigee, PayPal, and Microsoft.


JMeter is a free and open-source programme. It’s used in RESTful API performance checking.
