# About the Inventory API

The Inventory API allows you to manage stock levels for products in a Wix Stores catalog. The API tracks inventory per variant, so you can manage stock separately for each size, color, or other product option.

With the Inventory API, you can:

- Retrieve inventory information for a specific product or variant.
- Update inventory tracking settings and stock status for product variants.
- Increment or decrement inventory quantities for up to 300 variants across multiple products in a single call.
- Query inventory items with filtering, sorting, and paging.

## Inventory track modes

The Inventory API supports 2 track modes that determine how a product's stock status works:

- **Tracked inventory**, where `trackQuantity` is `true`: The `quantity` field determines stock status. When the quantity reaches 0, the variant becomes out of stock. The system automatically decrements quantity when a customer completes a purchase. Use the Increment Inventory and Decrement Inventory methods to manually adjust quantities.
- **Untracked inventory**, where `trackQuantity` is `false`: The `inStock` field controls stock status manually. The system doesn't decrement quantity on purchase. Use the Update Inventory Variants method to toggle `inStock` for each variant.

## Terminology

- **Inventory item:** The inventory record for a specific product. Contains tracking settings, variant-level stock data, and preorder configuration.
- **Variant:** A specific version of a product, such as a particular size or color. Each variant maintains its own stock data. Products without variants have a single default variant.
- **Tracked inventory:** An inventory mode where the `quantity` field determines stock status. The system automatically decrements quantity on purchase.
- **Untracked inventory:** An inventory mode where the `inStock` flag controls stock status manually. The system doesn't track or decrement quantity on purchase.
- **Preorder:** A feature that allows customers to purchase out-of-stock items. Preorder is available only for tracked inventory, and you can set a limit on the number of preorder purchases.
