The authentication header is typically included in the “Request Headers” section of the Network tab. However, if you’re not seeing the authentication header there, there are a few possible reasons and solutions:
Check the correct request: Ensure that you’re looking at the correct network request in the Network tab. If the authentication header is sent with a different request, you might need to locate and inspect that specific request.
Enable “Preserve log”: By default, Chrome DevTools clears the network log on page refresh. To preserve the log and capture the authentication header, right-click anywhere on the Network tab and make sure the “Preserve log” option is checked. This allows you to view the headers of all requests, including subsequent ones.
