Installation and updates

Postman is available as a native app for Mac, Windows (32-bit / 64-bit), and Linux (32-bit / 64-bit) operating systems.

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

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

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 10.9.

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. The ARM version of Windows is not supported.

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:

~/.local/share/applications/Postman.desktop

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

[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=/opt/Postman/app/Postman %U
Icon=/opt/Postman/app/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;

Postman supports Ubuntu 12.04 and later, Fedora 21, and Debian 8 and later.

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

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.

Import Export Data

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

Updating Postman

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.

Update Ready

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.

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.

update-error-dialog

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.

Write Permission Issue in DevTools

  • 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.

Multiple Updates Running Issue in DevTools

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. It you are on Postman version 6, you will have to migrate to Postman 7 and change the Snap channel to get the latest updates. For more information see Migrating to Postman 7.
