how to form this REST request as a header, basic auth

Question

This is how I would do this http request with curl

curl -v --basic --user USERNAME:PASSWORD

how would I set this as a header in a different REST client?

I can create curl commands in php, but in other GUI based rest clients I am unsure what part of the rest call "basic authentication" really falls in, is it in the body? in a header structured a certain way? thanks for the insight

Answer 1

Basic authentication in HTTP is achieved by setting the Authorization header equal to Basic token where the token is equal the base64 of username:password. Follow the link for more details.
