FetchRequestAs an illustration, here is how reference expansion looks at the underlying JSON transport level. Given a customer object:
{
"name": "John Doe"
"customerGroup": {
"typeId": "customer-group",
"id": "7ba61480-6a72-4a2a-a72e-cd39f75a7ef2"
}
}{
"name": "John Doe"
"customerGroup": {
typeId: "customer-group",
