I am new in integration. I have created RESTlet script in Netsuite. Now I want to pass customer ids from Salesforce to Netsuite. How to make a call from salesforce to Netsuite? 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;
           }
  
  
   const put = (requestBody) => {
  
       log.debug("Get Request Triggered",JSON.stringify(requestBody));
       var id = record.submitFields({
           type: record.Type.CUSTOMER,
           id: requestBody.customerid,
           values: {
               email: '[email protected]'
           },
           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}
  

  });
