The nice thing about the http command in Nushell is that you can interact with HTTP endpoints without the need to install any external tools. You can use several subcommands like get, post, put, delete and patch. Each of these commands has the options to specify request headers. You can use the option --headers or the short version -H followed by a list of header keys and values.

The http command in Nushell can be used to interact with HTTP endpoints. You can post data to an endpoint using the post subcommand. If you want to post JSON data than you can simply use a record data structure and use the argument --content-type application/json (or the shorthand -t application/json). Nushell will automatically convert the record data structure to JSON and use it as the body of the HTTP request.
