Generating a HAR file for troubleshooting
When troubleshooting complex issues, it is sometimes necessary for our customer support team to obtain additional information about the network requests that are generated in your browser while an issue occurs. A customer support team member may request that you record a HAR file, or a log of network requests, while that issue is occurring and then provide that to them for further analysis.
Instructions on How to get a HAR capture for Chrome, Internet Explorer / Edge and Firefox are available at https://toolbox.googleapps.com/apps/har_analyzer/.
Warning: Keep in mind that HAR files contain sensitive data, including content of the pages you downloaded while recording, your cookies, which will allow anyone with the HAR file to impersonate your account, all the information that you submitted while recording ( personal details, passwords, credit card numbers, etc.).
