API testing in software development: rules and stages

24.10.2025

In modern software development, API testing is a fundamental step. Postman is a widely used tool for this purpose, but the increasing emphasis on privacy and data protection has led to increased interest in alternative solutions, such as HITOP. This modern HTTP client for developers has become incredibly popular.

HITOP Key Features

The service offers features that are simply irresistible:

  1. With a sleek design, HITOP enables rapid request generation and sending. Users can easily customize headers, parameters, and request content, significantly increasing testing productivity.
  2. HITOP does not store user data on its own servers. All request and response processing is performed directly in the browser, minimizing the risk of compromising sensitive data.
  3. The tool is compatible with all key HTTP methods, including GET, POST, PUT, DELETE, and others, allowing for comprehensive testing of various API types.
  4. The service includes functionality for working with JSON and other data formats, simplifying the analysis of API responses. Users can easily transform and visualize data, making the testing process more understandable and visual.

Furthermore, HITOP supports plugins and extensions, allowing you to customize the tool to your needs and integrate it with other services.

How to test a REST API with HITOP?

Using the tool is truly simple and straightforward. Here are the main points:

  1. Using HITOP does not require installing additional software, as it runs directly in the browser. Simply open the tool in your web browser.
  2. Specify your preferred HTTP method and enter your API address. If necessary, configure parameters and request headers.
  3. Click the “Submit” button to send the request to the server. HITOP will display the received response, including the status code, headers, and response body. This allows for a quick assessment of the API’s response to your request.
  4. HITOP offers intuitive tools for analyzing the received information. You can view the response in various formats, such as JSON or XML, and use built-in functions to format and visualize the data. This makes it easier to understand the response structure and helps identify potential issues.

While Postman is a powerful tool for API testing, HITOP offers several key advantages, especially when it comes to privacy. HITOP requires no registration and doesn’t store user data, making it a safer choice for developers working with sensitive information. Furthermore, its simplicity and ease of use make it an excellent alternative for those looking for a quick and effective way to test APIs without unnecessary complications!
