The answer should be: [{"op": "increment", "path": "/items/0/OrderQty", "value": -5}] See: https://learn.microsoft.com/en-us/azure/cosmos-db/partial-document-update Increment This operator increments a field by the specified value. It can accept both positive and negative values. If the field doesn't exist, it creates the field and sets it to the specified value. Add If the target path specifies an element that already exists, its value is replaced. The value in the question is -5 so using Add would set the node to -5 not 5.

Path option is wrong. Here is the correct JSON [ { "op": "add", "path": "/items/0/OrderQty", "value": 5 } ]
