# UpdateMediaStorageConfiguration
<a name="API_UpdateMediaStorageConfiguration"></a>

Associates a `SignalingChannel` to a stream to store the media. There are two signaling modes that you can specify :
+ If `StorageStatus` is enabled, the data will be stored in the `StreamARN` provided. In order for WebRTC Ingestion to work, the stream must have data retention enabled.
+ If `StorageStatus` is disabled, no data will be stored, and the `StreamARN` parameter will not be needed. 

**Important**  
If `StorageStatus` is enabled, direct peer-to-peer (master-viewer) connections no longer occur. Peers connect directly to the storage session. You must call the `JoinStorageSession` API to trigger an SDP offer send and establish a connection between a peer and the storage session.
