Hi everyone 
We’re building sales force integration to netsuite sales order. How can we work with external id for list items such as product or currency. 

You can map each product using the Salesforce product ID as the external ID for each corresponding item in NetSuite. This approach ensures a reliable link (mapping) and product validation between the two systems. You can construct sales orders in NetSuite using data from Salesforce by utilizing the IDs from Salesforce as reference points.

here's an example code block from the link
```POST <http://demo123.suitetalk.api.netsuite.com/services/rest/record/v1/customer>
BODY {
  "firstName": "John",
  "lastName": "Smith",
  "isPerson": true,
  "externalId": "CID001",
  "subsidiary": {
  "id": "1"
  }
 } 

        ```
