How to call Netsuite RESTlet from salesforce or any other application?

I have created RESTlet script to perform CRUD operations. I am calling that RESTlet from Postman. I have no idea of how to call the RESTlet from salesforce or other application for integration purpose? How to pass application data to RESTlet parameters(requestParams, requestBody)? Please advice.

Below is sample RESTlet script,/**

• @NApiVersion 2.1

• @NScriptType Restlet*/define(['N/record'],

  (record) => {const get = (requestParams) => {log.debug("Get Request Triggered",JSON.stringify(requestParams));

       var objRecord = record.load({         type: record.Type.CUSTOMER,          id: requestParams.id,         isDynamic: true,     });     return objRecord;     //return "successful get request" } const put = (requestBody) => {     log.debug("Get Request Triggered",JSON.stringify(requestBody));     var id = record.submitFields({         type: record.Type.CUSTOMER,         id: requestBody.customerid,         values: {             email: 'monika.phalle@theblueflamelabs.com'         },         options: {             enableSourcing: false,             ignoreMandatoryFields : true         }     });     return{"status":"success","message":"successfully updated the customer with id"+id     } } const post = (requestBody) => {     //try{     log.debug("POST Request Triggered",JSON.stringify(requestBody));     var customerRecord = record.create({         type: requestBody.recordType      });      log.debug("customerRecord",customerRecord);      customerRecord.setValue({fieldId:'companyname', value:requestBody.companyname});      var cname=customerRecord.getValue({fieldId:'companyname'});      log.debug("cname",cname);      customerRecord.setValue({fieldId:'subsidiary', value:requestBody.subsidiary});      var customerId=customerRecord.save();      return JSON.stringify({'customerid':customerId,'message':'Craeted Successfully'}) } const doDelete = (requestParams) => {     record.delete({         type: record.Type.CUSTOMER,         id: requestParams.customerId,     }); } return {get, put, post, delete: doDelete}

  });
