Generating a HAR file for troubleshooting

When troubleshooting test transactions, it is sometimes necessary for us to obtain additional information about the network requests that are generated in your browser during the request.

Note: Keep in mind that HAR files contain sensitive data, including content of the pages you downloaded while recording and your cookies. This allows anyone with the HAR file to impersonate your account and all the information that you submitted while recording (personal details, passwords, credit card numbers, etc.).

 

Generation of the HAR file

In Chrome

  1. Open Chrome and go to the page where the issue is occurring.
  2. Look for the Vertical ellipsis button () and select More Tools > Developer Tools.
  3. From the panel opened, select the Network tab.
  4. Look for a round Record button ( ) in the upper left corner of the tab, and make sure it is red. If it is grey, click it once to start recording.
  5. Check the box Preserve log.
  6. Click the Clear button ( ) to clear out any existing logs from the Network tab.
  7. Reproduce the issue that you were experiencing before, while the network requests are being recorded.
  8. Once you have reproduced the issue, in Chrome, click Download. Then save the file to your computer: Save as HAR with Content

Note: The instructions are the same for a MAC computer or a Windows computer.
