# Swell

Swell is a headless ecommerce backend designed for modern storefronts. Violet integrates via Swell's API using a store secret key.

## Connection

Merchants provide a **Secret Key** and their **Store ID**. The secret key is generated in the Swell dashboard under **Developer → API Keys**. The store ID is the subdomain used to access the store (e.g. `my-store` from `my-store.swell.store`).

## Webhooks

Swell webhooks are registered automatically when a merchant connects. Violet listens for product and order lifecycle events.

## Notable Behavior

* **Headless-first**: Swell is designed as a headless backend, meaning the merchant may not have a traditional storefront URL. The store URL is derived from the store ID during connection.
* **Inventory**: Swell tracks inventory at the variant level. Stock quantities are synced during catalog synchronization.
