Workflow: Generating a HAR file for troubleshooting

In this tutorial, you'll learn how to generate network requests and error logs requested by Zendesk Customer Support. A member of the team may ask you to record a HAR file, or a log of network requests, while that issue occurs. To help troubleshoot any issues, include any browser console logs in addition to a HAR file.

Similarly, you may also collect Windows log files in addition to HAR files.

Note: A HAR file includes data such as the content of your cookies and the pages you downloaded while making the recording. Anyone with access to the HAR file can view the data submitted while recording, which may include personal data or other sensitive data. Secure your HAR files accordingly. Cloudflare released a HAR sanitizer to strip any sensitive information.

From the panel that appears, select the Network tab. You must keep the menu open while you reproduce the issue.

Optional: If Zendesk Customer Support requests a HAR file with WebSockets, select the Socket option in the Network tab. Reload your browser to start seeing the traffic over the WebSocket. Note that the Socket option does not capture all logs when downloading the HAR file, but for display filter purposes and download WebSocket logs only.

Look for a round record button in the upper left corner of the tab, and make sure it is red. If it is grey, click the button once to start recording.

If it isn't, check the Preserve log box.

Click the grey crossed circle button to clear any existing logs from the network tab.

Instructions for sending HAR files

Before you send a HAR file to Zendesk:

Rename AND zip or compress your HAR files.

Uncompressed HAR files are often over Zendesk attachment limits.

By default, HAR files use the page URL as the name of the file.

Files with .com extensions look suspicious to spam and phishing filters, give the HAR file a descriptive name that doesn't include their full URL.
