Where to input authentication in REST API?

Hi everyone.
I have seen video (latest) about REST API so I have a question if a REST API not support Oauth but it need authentication (username and password) when we access it, where I should input it? As I see there is no option for this case.

Thanks

I got the answer now.
We have to use "Authorization" as parameter (basic authentication), no username and password as parameter.
