### Watch configuration items
### Get configuration items using gRPC API
Using your [favorite language](https://grpc.io/docs/languages/), create a Dapr gRPC client from the [Dapr proto](https://github.com/dapr/dapr/blob/master/dapr/proto/runtime/v1/dapr.proto). The following examples show Java, C#, Python and Javascript clients.

##### Watch configuration items
Create a Dapr gRPC client from the [Dapr proto](https://github.com/dapr/dapr/blob/master/dapr/proto/runtime/v1/dapr.proto) using your [preferred language](https://grpc.io/docs/languages/). Then use the proto method `SubscribeConfigurationAlpha1` on your client stub to start subscribing to events. The method accepts the following request object:

Using this method, you can subscribe to changes in specific keys for a given configuration store. gRPC streaming varies widely based on language - see the [gRPC examples here](https://grpc.io/docs/languages/) for usage.
### Stop watching configuration items
##### Stop watching configuration items
After you have subscribed to watch configuration items, the gRPC-server stream starts. This stream thread does not close itself, and you have to do by explicitly call the `UnSubscribeConfigurationRequest` API. This method accepts the following request object:
