HTTP Query smart service

Hello Folks,

I am planing on using the HTTP Query smart service to consume REST API on an external system. Here are my questions
1. Does this smart service allow to make HTTPS calls?
2. If so, is there some configuration that needs to be done in Appian?
3. I need to make POST and DELETE calls. From documentation, appears this can be done.
4. How does authorization work? Can I use in the header like this: name: Authorization, value: "Bearer sxyslesmsdyyxxx"

Thanks in advance and Happy New Year.
