import {ok, notFound, serverError, created, badRequest} from 'wix-http-functions'; import wixData from 'wix-data'; // URL to call this HTTP function from your published site looks like: // Premium site - https://mysite.com/_functions/example/multiply?leftOperand=3&rightOperand=4 // Free site - https://username.wixsite.com/mysite/_functions/example/multiply?leftOperand=3&rightOperand=4
