# How can I generate a HAR file for troubleshooting?

To help you diagnose an issue, Payhawk Support may occasionally require additional information about the network activity in your browser.

While the issue is occurring, a Support team member can ask you to generate a HAR file - a log of network requests. Along with the HAR file, it's also helpful to include browser console logs.

> [!WARNING]
> HAR files can contain sensitive information, including cookies, downloaded page content, and any data submitted during the recording, potentially including personal or confidential information. Anyone with access to the HAR file may be able to view this data. To protect your privacy and security, always handle HAR files with care.

## Generating a HAR file in Chrome

To generate a HAR file in Chrome:

1. Open Chrome and navigate to the page where the issue is occurring.
2. Click on the three-dot button (**⋮**) and select **More Tools** > **Developer Tools**.

## Sending a HAR file to Payhawk Support

Before sending a HAR file to Payhawk Support, make sure to both rename and compress the file, as uncompressed HAR files often exceed Payhawk's attachment size limits.

HAR files are typically named using the page URL by default, which results in file names ending with .com that can trigger spam or phishing filters. To avoid this, give your HAR file a clear, descriptive name that does not include the full URL, and compress it into a ZIP file.
