Generating a HAR file for troubleshooting

Modified on Wed, 8 Oct at 5:50 PM

Our support team may occasionally need additional information about the network requests that are generated in your browser. A member of the team may ask you to record a HAR file, or a log of network requests, while that issue occurs. It's also helpful to include any browser console logs in addition to a HAR file. 

Click the tabs below to read the instructions to generate a HAR file and console logs in the browser that you use.

Chrome
Firefox
Safari
Edge
To generate a HAR file in Chrome
  1. Open Chrome and go to the page where the issue is occurring.
  2. Look for the  button and select More Tools > Developer Tools.
  3. From the panel that appears, select the Network tab. You must keep the menu open while you reproduce the issue. 

    Optional: If Customer Support requests a HAR file with WebSockets, select the WS option in the Network tab. Reload your browser to start seeing the traffic over the WebSocket.

  6. Click the crossed circle button to clear any existing logs from the network tab.
  7. Reproduce the issue while the network requests are recorded.
