Tagging SKU's in multipacks of primary bc on hand isn't on hand

We pull down the inventory but only the primary w 1 bottle has actual inventory.

How to tag the others so we can omit them from in our web app?

Hello @automate-it!
How are you pulling this information? Is it through our native integration, or have you built an API connection? If it’s the former, I suggest you submit a ticket by pressing the help button in the horizontal menu of the UI. This platform focuses on our Public API support. If it is the latter, please let me know how you handle the synchronization of inventory and products so I can look into it.
Have a great day!

Excellent will do. Can use the UI help for this and then pull what they recommend from the API.
