Upload file to REST Server

Could anyone tell me how to send data like name, id,etc and also file to REST Server?
The server is already ready, and I already can send form data from Postman application

use the vaRest plugin to form your JSON and sent it to your api backend. if you don’t want you can use regular http requests to transmit it

Thank you for your answer. I’ve tried that plugin and thats very useful. But now I have a problem to upload a CSV file to server. I want to send a data form that consists of fields: id (string), name (string), and file (.csv file). Could you tell me how to do that?
