- **Effective:** 2026-04-01
- **Severity:** medium
- **Change:** version-sunset

## What changed

As of Admin API version 2026-04, inventoryActivate without an available or onHand argument keeps an inventory level's earlier quantities instead of resetting them to zero.

## What to do

Pass available or onHand explicitly to inventoryActivate if your app relied on activation resetting quantities to zero.
