This article assumes that you have some NetSuite experience and have created a NetSuite Restlet. I have written a previous article that describes how to authenticate with NetSuite for calling a Restlet using token based authentication that should help you get up-to-speed.
To search for objects using NetSuite’s JavaScript Restlet implementation I will be using nlapiSearchRecord. Once the record has been found it will then be retrieved using nlapiLoadRecord.
