SKU Collection not specified BUG/ERROR in Webflow API

I’m trying to use the Webflow API to update product inventory and I keep getting this error:

SKU collection not specified (HTTP Status Code: 400)

I even get it in the Webflow docs simulator, even though I’m 100% sure I’m entering the correct collection ID and product ID.

Seems like this is a bug or there is information about an additional parameter missing from the docs, but I’m hoping someone might be able to help or has faced this issue before

I had the same bug, had to get in touch with support and here’s what I found. The issue is with the docs.

It requires that you use the Collection ID for the SKU collection, and then item ID of a SKU item, rather than the Product Collection ID and item ID.
