Promise = require("bluebird");

const RN_USER = process.env.RN_USER;
const RN_PASSWORD = process.env.RN_PASSWORD;
const RN_HOSTNAME = process.env.RN_HOSTNAME;
const RN_WSDL = process.env.RN_WSDL;
const SOAP_WSS_SECURITY = new soap.WSSecurity(RN_USER, RN_PASSWORD, {hasTimeStamp: false, hasTokenCreated: false});
const APP_API_ID = 'kobaton';

module.exports = class RightNow {

    static bot_rate_answer(interaction_id, content_id, rate, scale){
        debug("bot_rate_answer() started.");

        return RightNow.get_client().then(
            // Rate the content.
            (client) => {
                return RightNow.rate_content(client, interaction_id, content_id, rate, scale);
            }
