Netsuite Restlet Script

Hi there,

This post will cover everything about  Netsuite's Restlet script. Restlet Script is used to get data from Other System to Netsuite and also send data from Netsuite to external application securely. Restlet can perform any function what other suite script can.

Restlet can retrieve, add, or manipulate data within NetSuite, from an external source. In this sense, RESTlets can be seen as an alternative to NetSuite’s SOAP-based web services.

Restlet can customize the behavior of pages and features within NetSuite. In this sense, RESTlets can be seen an alternative to other script types, such as server-side Suitelets.

There are multiple advantage of restlet over suitelet.

Pros:
1. Restlets are more secure than suitelet in data transfer
2. Restlets have more type of methods and functionality compare to suitelet.
3. Can be used as an alternative to SOAP Based web services.
4. Login details are required to make a call.


Cons:
Restlets can not be used to show data as a form.

Restlets have 4 methods:
1. PUT
2. POST
3. GET
4. DELETE

 nlauth_email="myemail@gmail.com", nlauth_signature="mypass",

 nlauth_role="-4"

How to create Netsuite's Restlet in 2.0:

/**
 *@NApiVersion 2.x
 *@NScriptType Restlet
 */
define(['N/record', 'N/error'],
    function(record, error) {
       
        // Get a standard NetSuite record
        function mget(context) {
           
            return JSON.stringify(record.load({
                type: context.recordtype,
                id: context.id
            }));
        }
        // Delete a standard NetSuite record
        function mdelete(context) {
           
            record.delete({
                type: context.recordtype,
                id: context.id
            });
            return String(context.id);
        }
        // Create a NetSuite record from request params
        function mpost(context) {
          
            var rec = record.create({
                type: context.recordtype
            });
            rec.setValue(fldName, fieldValue);
                       
            var recordId = rec.save();
            return String(recordId);
        }
        // Upsert a NetSuite record from request param
        function mput(context) {
              var rec = record.load({
                type: context.recordtype,
                id: context.id
            });
          rec.setValue(fldName,fieldValue);
                       
            rec.save();
            return JSON.stringify(rec);
        }
        return {
            get: mget,
            delete: mdelete,
            post: mpost,
            put: mput
        };
    });


How to call suitelet?
If you use GET method , it should use params like below:
GET YRLofRestlet&recordtype=salesorder&id=1122 HTTP/1.1 HOST: URL authorization: NLAuth nlauth_account=12345, 
nlauth_email=netsuiteguru@netsuiteguru.com, nlauth_signature=URPassword content-type: application/json

How to know which Content-Type you need?

application/json :: JSON is the appropriate choice for most RESTlets that require a request body,

 because it lets you map values to fields.

application/xml :: XML is supported only for the get method.

text/plain :: Because plain text does not let you map values to fields, this choice should be used only

 for RESTlets that require limited and simple input.
