### What are Relations?

On Amazon, **Relations** link main products with their variation sub-products (for example, a T-shirt available in multiple sizes and colors). Grouping variations helps customers easily discover, compare, and purchase different options on a single detail page.

### Key Behaviors & Scope

* **Targeted Updates:** Updating relations only affects the parent-child variation structure on Amazon.
* **Excluded Attributes:** Transmitting relations will **not** modify product details, product attributes, prices, inventory levels, discounts, or tax settings.
* **Adding New Variations:** When expanding a product range (for example, adding extra sizes or colors to an existing listing), sending relations attaches the new variation options to the existing product.
