JSON_GetArray (JSON_object, id [, id, ... ])

Result type:  array

Definition:  Works like JSON_Get, except if the identified node is an object or an array rather than a simple value, the result will be an associative array containing the structured object data. You can pass just the top-level JSON handle from JSON_Parse to get the entire structure 

on LoadFromScriptEditor
    let jsontext = <<JSON
{
    "shipmentId": "SH12345",
    "origin": {
        "address": "123 Warehouse Lane",
        "city": "New York",
        "state": "NY",
        "zip": "10001",
        "country": "USA"
        },
    "destination": {
        "address": "456 Delivery Blvd",
        "city": "Los Angeles",
        "state": "CA",
        "zip": "90001",
        "country": "USA"
        }
    }
JSON
    
    let jsonhandle = JSON_Parse(jsontext)
    let a = JSON_GetArray(jsonhandle, "destination")
    foreach k in array a
        syslog(k + " = " + a[k]) 
    endfor
    JSON_Free(jsonhandle)
end

output: 

address = 456 Delivery Blvd
city = Los Angeles
country = USA
state = CA
zip = 90001

Availability:  available within MWScript handlers in MoneyWors v9.2.3 and later.
