Would it please be possible to add the 'incoming' property which is already available on the GraphQL endpoint to the REST endpoint?
(On a side note, I'm noticing quite a lot of discrepancies between GraphQL and Rest APIs.
There are numerous properties which are available in GraphQL and not REST, and vice versa.
It would be great to have more consistency and full parity...)
+1 We also need this information in InventoryLevel webhook.
