Get order_product_id from shipment
I'm trying to find the id, relating to the product of an order, from a shipment. When using the shipmentProduct endpoint I'm only getting an ID, I assumed this ID was related to the product ID from an order but this is not the case.
Your support sent me this screenshot, showing order_product_id:
What endpoint do I use to get this information? Support referred me to your API documentation, but I'm unable to find any reference to a order_product_id or anything that relates to that.
