+title: "Generating a HAR file"
+description: "How to capture a HAR file from your browser to help the Lightdash support team troubleshoot issues"
+---
+
+When troubleshooting issues with Lightdash, our support team may ask you to provide a **HAR (HTTP Archive) file**. A HAR file records all network requests between your browser and Lightdash, helping us diagnose loading failures, slow queries, API errors, and other issues.
+
+## Before you start
+
+<Warning>
+  HAR files contain sensitive data including **cookies, session tokens, and the content of pages you visited** during the recording. Anyone with access to a HAR file could use this information to impersonate your session.
+
+  **Before sharing a HAR file:**
+  - Only record the minimum steps needed to reproduce the issue
+  - Do not share HAR files publicly (e.g. in GitHub issues) — send them directly to the support team
+  - If possible, use [Cloudflare's HAR sanitizer](https://har-sanitizer.pages.dev/) to strip cookies and authorization headers before sharing
+</Warning>

+## Sending the HAR file to Lightdash support
+
+1. **Sanitize** the file using [Cloudflare's HAR sanitizer](https://har-sanitizer.pages.dev/) to remove sensitive headers and cookies
+2. **Compress** the file — HAR files can be large, so zip the file before sending (right-click the file and select **Compress** on Mac or **Send to > Compressed folder** on Windows)
+3. **Send** the file to [support@lightdash.com](mailto:support@lightdash.com) with a description of the issue, including:
+   - What you were trying to do
+   - What you expected to happen
+   - What actually happened
+   - The URL of the Lightdash page where the issue occurred
+
+<Note>
+  If the compressed HAR file is too large for email (over 25 MB), let the support team know and they'll provide an alternative upload method.
