How to Download and Install Postman and Fiddler

In this article, I will discuss How to Download and Install Postman and Fiddler. Please read our previous article, which discusses downloading and installing SSMS on the Windows operating system. At some point, we will work with the Web API, i.e., Restful Web Services; we also need one Web API client tool. We are going to use Postman and Fiddler in this course for the client tool.

What is Postman?

Postman is the most Popular API (Application Programming Interface) and the most powerful HTTP client tool developers and teams use to test restful web services. It provides a comprehensive environment for API development, enabling users to make HTTP requests, inspect responses, and automate testing processes.

How to Download Postman

• Visit the Postman Website: Open your web browser and go to the Postman download page: https://www.postman.com/downloads/
• Choose Your Platform: On the download page, select your operating system (Windows, macOS, or Linux).
• Download the Installer: Click the download button to download the installer for your selected platform.

How to Install Postman on Windows

• Run the Installer: Once the download is complete, locate the downloaded file (e.g., Postman-win64-setup.exe) and double-click it to run the installer.
• Follow the Installation Wizard: The installer will open. Follow the on-screen instructions to install Postman. Typically, you will need to agree to the terms and conditions and choose an installation location.
• Launch Postman: After the installation is complete, Postman will launch automatically. You can also find it in your Start menu.

Downloading and Installing Postman:

In order to install Postman, please visit the below link.

https://www.postman.com/downloads/

Once you click the above link, it will open the webpage below. From the page below, click on the Download the App link to download Postman on your machine. Depending upon your operating system, you can choose either 32-bit or 64-bit. I have installed the 64-bit operating system, so I chose Windows 64-bit, as shown in the image below.

Once you download it, then install it. While installing, it will ask you to sign in using your Gmail Credentials. Later. I will show you how to use Postman with ASP.NET Core Web API.

Key Features of Postman

• API Request Building: Create and send various types of HTTP requests (GET, POST, PUT, DELETE, etc.) to test and interact with APIs.
• Response Visualization: Inspect and visualize API responses with support for different formats like JSON, XML, HTML, and plain text.
• Collections: Organize API requests into collections for better management and reusability. Collections can be shared with team members.
• Environments: Create environments to manage different configurations (e.g., development, staging, production) and switch between them easily.
• Automated Testing: Write test scripts in JavaScript to automate testing and validation of API responses.
• API Documentation: Automatically generate and publish API documentation from collections, making it easier to share API details with others.
• Monitoring: Set up monitors to run API requests at scheduled intervals and track performance and uptime.

What is Fiddler?

Fiddler is a web debugging proxy tool that captures and inspects HTTP(S) traffic between your computer and the internet. It is widely used by developers, network administrators, testers, and IT professionals to diagnose issues with web applications, APIs, and services. Let’s see how to download and install Fiddler.

How to Download Fiddler?

• Visit the Fiddler Website: Open your web browser and go to the Fiddler download page.
• Choose Your Version: Fiddler offers different versions, such as Fiddler Everywhere, Fiddler Classic, Fiddler Jam, etc. For most users, Fiddler Everywhere or Fiddler Classic is suitable. Select the version that fits your needs.
• Download the Installer: Click the download button for the version you selected. This will download the installer to your computer.

How to Install Fiddler on Windows?

• Run the Installer: Once the download is complete, locate the downloaded file (e.g., FiddlerSetup.exe for Fiddler Classic or FiddlerEverywhere.exe for Fiddler Everywhere) and double-click it to run the installer.
• Follow the Installation Wizard: The installation wizard will open. Follow the on-screen instructions to install Fiddler. This typically includes agreeing to the terms and conditions and choosing an installation location.
• Launch Fiddler: After the installation is complete, Fiddler will launch automatically. You can also find it in your Start menu or desktop shortcut.

To Download Fiddler Classic, please visit the following URL.

https://www.telerik.com/download/fiddler

Once you visit the above website, it will ask you what purpose you want to use Fiddler, your email ID, and your country, as shown in the image below. Once you provide this information, click on the Download button.

Later, I will show you how to use Fiddler to capture the request and response.

Key Features of Fiddler

The following are some of the key features and benefits of using Fiddler:

• Traffic Capture: Fiddler captures all HTTP and HTTPS traffic between your computer and the internet, making it easy to see what data is being sent and received.
• Request and Response Inspection: Detailed inspection of HTTP requests and responses, including headers, cookies, caching information, and payloads.
• Traffic Manipulation: Modify HTTP requests and responses on the fly. This is useful for testing how changes impact web applications.
• Session Analysis: Analyze sessions to identify performance bottlenecks, security issues, and other problems. View timing details, session statistics, and more.
• Decryption of HTTPS Traffic: Fiddler can decrypt HTTPS traffic, allowing you to inspect encrypted sessions.
• Performance Testing: Measure and analyze the performance of web applications by inspecting load times and other performance metrics.
• Security Testing: Test web applications for security vulnerabilities by inspecting and manipulating SSL/TLS traffic.
• API Testing: Test and debug RESTful APIs by capturing and inspecting API requests and responses.

In the next article, I will discuss the .NET Core vs. .NET Framework Code Execution Process. In this article, I try to explain how to download and install Postman and Fiddler. I hope you enjoy this Download and Install Postman and Fiddler article.
