How to Collect HAR Files in HubSpot for Support

When you run into technical issues with Hubspot, support may ask you to collect a HAR (HTTP Archive) file. This file records network activity in your browser and helps diagnose errors such as pages not loading, timeouts, or unexpected behavior in your account.

This step-by-step guide explains how to generate a HAR file in the most common browsers so you can quickly share it with HubSpot support or a technical partner.

What is a HAR File and Why HubSpot Support Needs It

A HAR file is a log of all network requests your browser makes while you interact with a page. It includes details such as URLs called, response codes, load times, and possible failures.

When HubSpot tools do not behave as expected, a HAR file helps support teams:

  • Reproduce intermittent issues more accurately.
  • See failed or slow network requests.
  • Identify conflicts with browser extensions or caching.
  • Understand how your browser loads HubSpot resources.

You should only record a HAR file when requested or when you are ready to share it securely with an authorized support team.

Before You Start: General Tips for HubSpot Troubleshooting

Before collecting a HAR file, follow these best practices to capture useful data for your HubSpot troubleshooting session:

  • Use an incognito or private browsing window if possible.
  • Disable unnecessary browser extensions during testing.
  • Make sure you are logged into your HubSpot account.
  • Reproduce the issue from the exact page or tool where the problem occurs.

Once you are ready, follow the browser-specific instructions below.

How to Collect a HAR File in Chrome for HubSpot

Google Chrome is one of the most common browsers used to access HubSpot. Use these steps to record a HAR file while reproducing your issue.

Chrome: Step-by-Step Instructions for HubSpot Pages

  1. Open Chrome and go to the specific HubSpot page where the problem occurs.

  2. Right-click anywhere on the page and select Inspect, or press Ctrl+Shift+I (Windows) or Cmd+Opt+I (Mac).

  3. In the Developer Tools panel, click the Network tab.

  4. Check that the Preserve log option is enabled so the log is not cleared when the page reloads.

  5. Reload the HubSpot page by pressing Ctrl+R (Windows) or Cmd+R (Mac), or by clicking the refresh icon.

  6. Perform the exact actions that cause the issue within your HubSpot account, such as opening a record, submitting a form, or running a workflow.

  7. After the issue appears, right-click anywhere in the list of network requests and choose Save all as HAR with content or Save as HAR with content.

  8. Save the HAR file to your computer with a descriptive name, for example, hubspot-issue-chrome.har.

You can now attach this file to your HubSpot support ticket or send it securely to a technical contact.

How to Collect a HAR File in Firefox for HubSpot

If you use Mozilla Firefox to work in HubSpot, you can also generate a HAR file with its built-in developer tools.

  3. Select the Network tab in the Developer Tools panel.

  4. Ensure logging is enabled and clear any previous results if necessary.

  5. Reload the HubSpot page so Firefox starts capturing the full sequence of requests.

  6. Reproduce the HubSpot issue: click, navigate, or submit forms exactly as you did when the problem appeared.

  7. When the issue has occurred, right-click in the list of network entries and choose Save all as HAR or a similar option.

  8. Save the file to your computer and give it a clear name, such as hubspot-issue-firefox.har.

Include this HAR file with any screenshots or error descriptions you are sending to support.

  7. Save the HAR file with a descriptive name and include it with your support request.

Sharing Your HAR File with HubSpot or a Partner

Once you have collected your HAR file from any browser, follow these common guidelines:

  • Attach the HAR file directly to your HubSpot support ticket if file uploads are enabled.
  • If sending via email, compress the HAR file into a ZIP archive when possible.
  • Share the file only with trusted teams, such as HubSpot support or a certified solutions partner.
  • Do not publish HAR files publicly, as they can include sensitive data such as URLs, tokens, or form submissions.

Many organizations also work with external experts for complex implementations and troubleshooting. For example, you can find advanced CRM and RevOps help from partners like Consultevo.
