Events are raised when changes are made to prices and inventories, triggering the indexing of updated content.

## Price updated event from custom price service

The default price service, `PriceServiceDatabase`, raises an event when a price is changed. This allows `EPiServer.Find.Commerce` to re-index the variant content with updated prices.

To re-index variant content when a price is updated, modify a custom price service as follows:

1. Add a dependency to `Mediachase.Commerce.Engine.Events.CatalogKeyEventBroadcaster` in your service.
2. Call `OnPriceUpdated(priceValues, new PriceUpdateEventArgs(catalogKeys))` on the `CatalogKeyEventBroadcaster` instance when a price has been added, updated, or removed. Here, `catalogKeys` is an `{'IEnumerable<CatalogKey>'}` that references the variants to which the prices belong.

## Inventory updated event from custom inventory service

The default inventory service, `InventoryDatabase`, raises an event when an inventory is changed. This allows [EPiServer.Find.Commerce](https://world.optimizely.com/blogs/Jonas-Bergqvist/Dates/2015/11/new-version-of-episerver-find-commerce/) to re-index variant content with updated inventory information.

To enable re-indexing of variant content when an inventory is updated, a custom inventory service must be modified:

1. Add a dependency to `Mediachase.Commerce.Engine.Events.CatalogKeyEventBroadcaster` in your service.
2. Call `OnInventoryUpdated(inventory, new InventoryUpdateEventArgs(catalogKeys))` on the `CatalogKeyEventBroadcaster` instance when an inventory is added/updated/removed. Here, `catalogKeys` is an `{'IEnumerable<CatalogKey>'}` that references the variants to which the inventories belong.
   If the inventory is deleted, the event will contain an empty list of inventory items and a list of `CatalogKey`s for the deleted inventory.
