How to set custom segment header / main value of a sales order in a rest web service payload /request?

AI generated answer (using internal Slack threads):

To set a custom segment header or main value of a sales order in a REST web service payload/request, you would need to include the custom segment in the payload of your request. Here is a general example of how you might structure your payload:

json
{
  "recordType": "salesOrder",
  "fields": {
    "entity": {
      "id": "123"
    },
    "customSegment": {
      "id": "custom_segment_id",
      "value": "custom_segment_value"
    }
  }
}

In this example,

custom_segment_id

would be the internal ID of your custom segment, and

custom_segment_value

would be the value you want to set for that custom segment. Please note that the actual field name for your custom segment may vary depending on how it was set up in NetSuite. You may need to refer to your NetSuite account or the SuiteTalk WSDL to find the correct field name. Also, if you're using a version of the SuiteTalk API that's older than 2019.2, setting a value for a custom segment may be more complicated. You might need to modify your schema or use scripting to write to a regular custom field and then use a script to push that value to the custom segment. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
