Downloading & Uploading HAR Files (Web)


HAR files, short for HTTP Archive, track the history of information passed between the website and the browser. These fairly large files contain a vault of useful information including the network requests fired from all of the events fired (page load, click, scroll, etc.) during a session.

Note: This feature might not be available to you currently. If so, reach out to your Customer Success Manager or our support team if you want to request access.

Downloading a HAR File

HAR files can be download easily from a Web Browser. 

Note: In this example, we'll show how to download the file in a Chrome browser, but it is accessible in other browsers as well.
  1. Open the DevTools and select the Network tab.
  2. Ensure the round button at the top left of the DevTools window is red and select the Preserve Logs option.
  3. Once you have recreated what you would like to capture, you can save the HAR file by right-clicking anywhere in the table and selecting "Save as HAR with content" or you can click the download icon highlighted in the image below.
Note:  If you want to see how this is done on a mobile device, click  here .
