In the response Header section, I do not have "Allow" key

For all my requests, when I go to response, in the Header, there is no “Allow” key information, which tells what methods are allowed to be used for the specific request. it only shows Allow when I choose “Options”.
How can I see “Allow” in Header in the response section when I use GET or POST?

The headers are generally controlled by the API, so if it’s missing an element, its usually because that specific API isn’t generating it.

Do you mean the “Accept” header?

If not, can you screenshot an example using the options to confirm what element we are talking about. (I’m not sure what “options” you are talking about").

Example request\response using Postman Echo. (This is accepting everything).
