[GregW (accepted answer)] I am trying to do the same thing (different programming language). I have a call into their support. It seems like you still must reference the product_id. You cannot update simply by SKU. You must know the product_id. I got around this by requesting all products and loading the response into an array (product_id, sku, etc.). I then read thru the array, get the quantity from our system using the SKU, and post (PUT) the inventory_level using the associated product_id. IMHO this is a huge oversight on their part. Who cares what the product_id is on the website? I have asked for an enhancement that allows updating by SKU.
