Shipment Orders API issue

Shipment Orders API issue

Hi!

I'm trying to extract  shipmentorder_id from the Shipment Orders API, so to be able to mark as delivered a package.
Problem is that I cant find where this key is.

I also tried by listing all packages but no key like that one is given, so how can i  POST /shipmentorders/{shipmentorder_id}/status/delivered ?

Thanks :)
