# Retrieve an Asset’s Content Protection Key

Provide the content key for a specific protected asset.

## Discussion

If your service implements content protection, the client requests an item’s content protection key from this endpoint after each of the following events:

- The client receives the queue’s initial item.
- The client preloads each subsequent item in the queue.
- The user manually transitions to an item in the queue.

For more information on providing your service’s content protection configuration, see [`ExtensionConfig.Media.Queues.ContentProtectionKey`](/documentation/SiriKitCloudMedia/ExtensionConfig/Media-data.dictionary/Queues-data.dictionary/ContentProtectionKey-data.dictionary).
