Thanks again @garyrgilbert for taking time to reply.
The issue I’m experiencing is if (for example) I request:
admin/api/2023-01/orders/4564975779888/fulfillment_orders.json
I get a valid response but no fulfillment orders:
{
“fulfillment_orders”:
}
The API documentation suggests there will always bee fulfillment orders automatically created when an order is made?
