Orders API: "mixed usage of applied adjustments fields with deprecated adjustments fields is not supported"

Ah, I see. Thanks!

Any idea why it might be telling me it can’t find the catalog object ID even though I can see it using RetrieveCatalogObject?

Also, it’s telling me that applied_money for applied_discount is read only. What’s the correct way to change a discount amount from code if we want to use applied_discounts?
