# Generating a HAR file

> Learn how to generate a HAR file to help troubleshoot issues with Dynamic

When troubleshooting issues, our support team may ask you to provide a HAR (HTTP Archive) file. This file captures all network requests made by your browser, helping us diagnose problems more effectively.

## What is a HAR file?

A HAR file is a JSON-formatted log of your browser's network activity. It records all HTTP requests and responses, including headers, cookies, timing information, and response content. This data helps identify issues like failed API calls, slow responses, or unexpected errors.

<Warning>
  HAR files contain sensitive data including cookies, authentication tokens, and page content. Before sharing, consider using a [HAR sanitizer](https://blog.cloudflare.com/introducing-har-sanitizer-secure-har-sharing/) to remove sensitive information.

## Sending HAR files to support

Before sending your HAR file:

1. **Rename the file** - HAR files often use the page URL as the filename, which can trigger spam filters. Use a descriptive name like `dynamic-issue-har.har`
2. **Compress the file** - HAR files can be large. Zip or compress the file before sending
3. **Remove sensitive data** - Consider using a [HAR sanitizer](https://blog.cloudflare.com/introducing-har-sanitizer-secure-har-sharing/) to strip cookies and tokens

Share the HAR file with our support team via [Slack](https://dynamic.xyz/slack) in the `#bug-report` channel, or attach it to your support ticket.
