This sample retrieves information about a snapshot.

## Code sample

### Go


Before trying this sample, follow the Go setup instructions in the
[Compute Engine quickstart using
client libraries](https://docs.cloud.google.com/compute/docs/api/using-libraries).


For more information, see the
[Compute Engine Go API
reference documentation](https://docs.cloud.google.com/go/docs/reference/cloud.google.com/go/compute/latest/apiv1).


To authenticate to Compute Engine, set up Application Default Credentials.

    	}
    	defer snapshotsClient.Close()

    	reqSnapshot := &computepb.GetSnapshotRequest{
