Summary

If you're experiencing technical issues with 7taps, our support team may request a HAR (HTTP Archive) file. This file captures detailed network activity in your browser and helps us diagnose what's happening behind the scenes. This guide walks you through creating a HAR file in Google Chrome—the entire process takes less than 2 minutes.


When You'll Need This

Our support team will ask for a HAR file when:

  • Pages aren't loading correctly

  • Features aren't working as expected

  • Error messages appear without clear explanation

  • We need to see exactly what's happening in your browser during the issue

Important: The HAR file captures network activity, so only record while reproducing the specific issue you're reporting.


Step-by-Step Instructions

1. Open Google Chrome and Navigate to the Problem Area

Go to the specific page where you're experiencing the issue. Don't try to reproduce the problem yet—just get to the right location.


2. Open Developer Tools

Click the three-dot menu (⋮) in the upper right corner of Chrome (all the way to the right of your address bar and extension icons).

Select: More Tools → Developer Tools

Keyboard shortcut:

  • Mac: Option + Command + I

  • Windows: Ctrl + Shift + I

3. Navigate to the Network Tab

The Developer Tools panel will open at the bottom or side of your browser window.

Look for the row of tabs at the top of this panel: Elements, Console, Sources, Network, etc.

Click the Network tab.

Can't see the Network tab? Click the double-right-arrow button (») on the right side of the tab row to reveal hidden tabs.

4. Enable Preserve Log

In the Network tab, check the box labeled Preserve Log.

This ensures that all activity is captured, even if the page refreshes during your testing.

5. Start Recording (If Not Already Active)

Look for a circular recording button near the top-left of the Network panel:

  • Red circle (🔴) = Recording is active

  • Black or grey circle (○) = Recording is stopped

If the circle is black or grey, click it once to start recording. It should turn red.

6. Reproduce the Issue

Now perform the actions that trigger the problem you're experiencing:

  • Refresh the page

  • Click the button that's causing issues

  • Complete the workflow that's failing

As you work, you'll see activity being logged in the Network tab—this is normal and expected.

7. Stop Recording

Once you've reproduced the issue, click the red circle (🔴) to stop recording.


8. Export the HAR File

Click the download button (↓) in the Network tab toolbar. When you hover over it, you'll see "Export HAR" appear.

  2. Give it a descriptive name (e.g., 7taps-issue-2024-01-15.har)

  3. Keep the .har file extension

  4. Click Save

10. Share with Support

Attach the HAR file to your support ticket or email it to our team along with a description of the issue you were experiencing.

You can now close the Developer Tools panel—just click the X in the upper right corner of the panel.


Privacy Note

HAR files contain details about your browser activity on the recorded pages, including URLs and potentially sensitive data.
