Installing and updating

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

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

Installing Postman on the desktop

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 10.10 (Yosemite).

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 provided for Windows. Windows for ARM devices is possible by using the ia32 binary.

Installing Postman on Linux

You can install Postman on Linux by downloading it—or via the Snap store link / using 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 12.04 and newer
• Fedora 21
• Debian 8 and newer

The support of certain Linux distributions depends on whether they are supported by Electron or not. 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 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 to ensure a smooth Postman run: 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/build in your browser. 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 this 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.

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 click 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

Postman for the Web is still under development. Please try it out and give the team feedback by joining in the discussion on the community forum.

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 via 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 whitelist the following domains to allow 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 whitelist 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 via 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 are on Postman version 6, you will have to migrate to Postman 8 and change the Snap channel to get the latest updates. For more information see Migrating to Postman 8.

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!
