Steps
Authenticate and obtain a FoodStorm API access token
Identify the item ID and the quantity change resulting from a completed POS sale
Send the adjustment to /v1/items/quantitylimits/adjustments with the item and quantity delta
Confirm FoodStorm's displayed remaining quantity reflects the adjustment before the next order is placed
Reconcile discrepancies if the POS and FoodStorm quantities drift out of sync
Known gotchas
This endpoint is specifically for quantity-limit adjustments tied to POS transactions, not for general item updates - use the Items API for catalog changes
Race conditions are possible if multiple POS terminals submit adjustments for the same item concurrently; serialize updates per item where possible
