How to Generate a HAR File

A HTTP Archive (HAR) records all web browser requests including the request and response headers, the body content, and the page load time.

A HAR file can include sensitive details such as passwords, payment information, and private keys. You can manually remove sensitive information from a HAR file via a text editor before providing to your Twelve Legs Marketing Support team.

Currently, only Chrome and Firefox can access the HAR feature by default. Other browsers either require a browser extension or cannot generate a HAR. When installing a browser extension, follow the instructions from the extension provider.
