[Answered ]-Chrome Postman – how to avoid unnecessary headers

In the settings dialog, there is a ‘Send postman-token header’ option.

This is only available in the packaged app (https://chrome.google.com/webstore/detail/postman-rest-client-packa/fhbjgbiflinjbdggehcddcbncdddomop?hl=en), though, not in the in-chrome version.
