title: How to enter x-auth header in postman?
body: <p>So I receive an API credential that asks me to enter an X-AUTH-HEADER and Content-Type.</p>
  
  <p>In my postman, on the "Headers" tab, there's a "Content Type" key but I can't see an "X-Auth-Header" key. I only have "Authorization" key. Where to I enter the X-Auth-Header key then?</p>
