Installing and updating

Postman is available on the web at go.postman.co/home and as a native desktop app for Mac, Windows (32-bit / 64-bit), and Linux (64-bit) operating systems.

To get the latest version of the Postman desktop app, visit the download page and select Download for your platform.

• Installing Postman on the desktop
  • Mac
  • Windows
  • Linux
• Using Postman on the web
  • Browser requirements
  • Installing the Postman desktop agent
  • Web limitations
• Updating Postman
• Chrome app (deprecated)
  • Migrating to the native app
• Using Postman behind a firewall
• Troubleshooting your Postman installation
• Next steps

Note that the Postman team only tests, fixes bugs, and provides support for the app on Mac, Windows, Linux, and the web.

Installing Postman on Mac

Download and unzip the app using the built-in Archive Utility app. Double-click Postman. When prompted, move the file to your Applications folder—this will ensure that future updates can be installed correctly.

The minimum OS version supported is macOS 10.11 (El Capitan).

You may encounter a «Library not loaded» error if you attempt to unzip and install Postman using a third-party app—using the default Archive Utility for Mac should resolve this.

Installing Postman on Windows

Download the app. Double-click the exe file to install it.

Postman supports Windows 7 and above. Both ia32 (x86) and x64 (amd64) installers are available for Windows. Windows for ARM devices is possible by using the ia32 binary.

Installing Postman on Linux

You can install Postman on Linux by manually downloading it, using the Snap store link, or with the command snap install postman .

To install manually, download and unzip the app, for example into the opt directory. You will need sudo privileges.

To start the app from a launcher icon, create a desktop file, naming it Postman.desktop and saving it in the following location:

Enter the following content in the file—replacing opt if you extracted the file somewhere else—and save it:

Postman supports the following distributions:

• Ubuntu 14.04 and newer
• Fedora 24
• Debian 8 and newer

The support of certain Linux distributions depends on if they are supported by Electron. Refer to Electron’s documentation.

It is recommended you install Snap as it includes all the libraries that the app needs and they are bundled with the app itself.

Avoid starting Postman using the sudo command, as it will create permission issues on the files created by Postman.

Make sure you have read/write permission for the

/.config folder where Postman stores information.

If you are an Ubuntu 18 user, you will also need to install the libgconf-2-4 package with the command apt-get install libgconf-2-4

Using Postman on the web

You can use Postman in your web browser to carry out your API development and testing tasks in conjunction with the Postman Agent. To access Postman on the web, visit go.postman.co/home.

Postman’s web application is optimized for the following browsers:

• Chrome (78 and higher)
• Firefox (76 and higher)
• Edge (79 and higher)
• Safari (13.1.1 and higher)

Installing the Postman desktop agent

If you are using the Postman web client, you will need to also download the Postman desktop agent. You will be prompted to download and install the agent so that you can make requests from the web. You can also download the agent directly from the Downloads page.

The Postman agent overcomes the Cross Object Resource Sharing (CORS) limitations of browsers, and facilitates API request sending from your browser version of Postman. Once you have the agent installed you will be able to use it with web requests.

You can either enable Auto-select option or manually select the agent (Cloud, Desktop, or Browser) you would like to use for your requests.

Once you enable the option for Auto-select, Postman will automatically select the best agent for your requests.

You can select the Cloud Agent if you want to send HTTP requests via Postman’s secure cloud servers. While using the locally running Postman, it is recommended you use the Desktop Agent. Using the Browser Agent for your web requests has some limitations.

If you try to send a request and it isn’t successful because the agent is not selected, you will see a link in the response area which you can select to switch to the agent and try your request again. Read more about the agent.

Postman on the web is under active development, but there are a few features you can currently only access in the desktop app and not in your web browser:

• Live preview: You will not see all of your request headers update live as you enter your request configurations as you do in the desktop Postman app—you will only see Authorization headers update as you edit.
• Saving responses to file
• Certificates and Proxy: These will take the browser defined value and cannot be overridden by Postman.
• Postman Interceptor

The native Postman apps will notify you when a major update is available. For other updates you will see a dot on the settings icon. If the indicator is red instead of orange, it indicates a failed update.

Select the update option to download or install the latest update. You will see a notification when the download is complete, prompting you to restart the Postman app to apply the updates. If you’re not ready to update yet, choose Later to auto-update the next time you launch the app.

You can configure your preferences to enable automatic download for major updates in Settings > Update. Postman automatically downloads minor updates and bug fixes.

Postman Chrome app (deprecated)

The Postman Chrome app is deprecated—if you’re using the Chrome app, you can retain your data when you switch to the native app either by syncing with a Postman account you’re signed into, or by exporting from Chrome and importing into the native app.

The native app is built on Electron, and overcomes a number of restrictions of the Chrome platform.

• The native apps let you work with cookies directly.
• Unlike the Chrome app, no separate extension for the Interceptor is needed.
• The native apps come with a built-in proxy that you can use to capture network traffic.
• The native apps are not restricted by the Chrome standards for the menu bar. You can check for updates, create Postman Windows and tabs, and edit preferences.
• The native apps let you send headers like Origin and User-Agent . These are restricted in the Chrome app.
• The «don’t follow redirects» option exists in the native apps to prevent requests that return a 300-series response from being automatically redirected—doing this in the Chrome app requires the Interceptor extension.
• The native app has a built-in console, which allows you to view the network request details for API calls.

Migrating to the native app

To switch from the Chrome app to native, download Postman and sign in to your account. Start the native app, and your history and collections will be automatically synced.

Alternatively, if you don’t want to sign in to your Postman account, you can bulk export your Postman data from the Chrome app, and then bulk import into the new native app at Settings > Data.

Note that importing will overwrite your existing data. For more on bulk import, see Importing Postman data.

Using Postman behind a firewall

Postman’s infrastructure runs on Amazon’s AWS platform. If you are operating behind a network firewall, you will need to allow the following domains to make WebSocket connections for Postman:

By default, WebSocket connections use the same ports as HTTP (80) and HTTPS (443).

Postman does not have a fixed IP range that can be provided. If necessary, please refer to the current AWS IP ranges and allow the broad range provided.

Troubleshooting your Postman installation

If you encounter any issues installing and running Postman, check out the following tips. If these do not help, please refer to the installation posts on the community forum and create a new post if your issue is not already covered.

Update failed error

If you see an Update Failed notification in Postman, you can use the DevTools to investigate.

Open the DevTools using View > Developer > Show DevTools (Current View). Some known errors are as follows:

• Error message: Cannot update while running on a read-only volume
  • This error means that the app user does not have write permission in the directory where Postman is installed. To resolve the problem, move Postman to a directory where the user has write permissions, for example the /Application directory for Mac, and to the home directory for Linux.

• Error message: Code signature at URL file:///. did not pass validation: code object is not signed at all
  • This error means that there are multiple updates running at the same time. This can happen when the app is opened before the previous update could finish. To resolve the problem, quit and reopen the app.

Update button not available

If you are using Postman for Linux, and installed the app with the Ubuntu Software Center or Snap Store, you may not see a Check for updates button. This is because the updates are handled by the store, which should automatically update Postman on a regular cadence.

If you’re having trouble with installation or updates, reach out for Postman support. If your installation is working as expected, send your first request!

Download Postman and Install On Windows and MacOS

Download and Install Postman

Since you now know about the application and have become familiar with its working, its time to install the application on your system. In this chapter we will cover How to Download and Install Postman on Windows Machine.

Postman is available for Windows, Linux and Mac as a standalone application. You can install the application in two ways.

• As a Standalone Application.
• As a Chrome Extension

We will be discussing both the methods in detail.

Download POSTMAN as a Standalone Application

A native application means the application will not be supportive of any particular application on an operating system. For example if you install an extension from chrome webstore then that application or extension will only run on chrome and no other browser. A native application is like any software that you install like a game or IDM or any antivirus for instance. A native application takes support of just your operating system and not another application because they are written system specific and not application specific.

Note: If you are using windows then there is an option for downloading for 32 bit system and 64 bit system. If you are using 64 bit windows then select x64 and if you are using 32 bit system then select x86. Default value is x64.

1. Choose the Operating System on which you want to download PostMan and click on «Download» button. Since I have got Windows 64-bit machine, I am going to install x64-Windows.

3. Once you download the exe file, you will be need to install the application. Since I am using Chrome browser, the downloaded exe will appear at the bottom left of the browser.

1. Click on the exe file to install it on the system. First it will install the POSTMAN application.

1. There is no further steps for installing. After completion, it will automatically start opening the PostMan tool.

1. Once you have the application window up, click on Take me straight to the app. I’ll create an account another time as highlighted. Alternatively, you can sign up with google but it does not matter at present.

If you see this page then you have successfully installed Postman on your system.

Download POSTMAN as a Chrome Extension

1. This will display a pop up to add extension, click on Add app.

1. Now it will automatically open a Chrome Apps page, where it will display all the installed apps on your chrome browser. Simply click on the PostMan application.

1. It will take few seconds to start, hold on till then 🙂

1. Once done, you would see the PostMan application registration page. As mentioned above, we will ignore registration as of now but not to avoid, *Registration has its own benefits, as it always stores your data and which can be accessible from different machines and location. *But we will cover that later.

Why to prefer PostMan as a Stand Alone application

Although Postman was introduced first as a chrome application and was powerful earlier on, we highly recommend downloading postman as an application for your operative system(native application) rather than as an extension for chrome.

There are two main reason for this.

• First of all, postman as an application for chrome does not support all the features that the native app has. For example proxy cannot be captured in chrome app. You need to install another extension called postman interceptor in order to work the proxy through the browser. A proxy server acts as an intermediary that captures the requests that you send through your browser to the server. Requests are anything like any web address or any search query or anything that asks for a response from server. For example, when you hit «Search» in google after writing something in the search bar, it is an API request or you type www.google.co.in in the address bar, it is an API request. After installing postman interceptor only you can capture the requests that you send. Moreover, Postman features less menu options in its chrome app, only those which adhere to the chrome standards. Therefore you won’t be able to enjoy every feature of Postman while using it as an chrome application.
• The second reason is the main concern for us to not recommend you, download postman, for chrome. As stated on the Postman website, Postman builders have stopped the support for the chrome application. This in simple terms means that from January 2018 onwards, there will be no updates, no bug fixes, no improvements in the chrome application. The app that is currently available on the web store is the final application. Moreover, if you are stuck on any issue, there will be no one to resolve it from Postman. This step is taken by Postman after Google announced that it will be ending support for the Chrome apps for Windows, Linux and Mac.

As it can be seen in the below image taken from the postman website, the last update for Chrome app was in 18 Oct, 2017. So, it is better that you install the Standalone application and the same will be used by us for this course.

In the next chapter we will run through some basics and terminologies about the Postman.
