## Await for messages and send messages { #await-for-messages-and-send-messages }

In your WebSocket route you can `await` for messages and send messages.

{* ../../docs_src/websockets/tutorial001_py39.py hl[48:52] *}

You can receive and send binary, text, and JSON data.

## Try it { #try-it }

If your file is named `main.py`, run your application with:

}

func getBucketTrafficSentBytes() MetricDescription {
	return MetricDescription{
		Namespace: bucketMetricNamespace,
		Subsystem: trafficSubsystem,
		Name:      sentBytes,
		Help:      "Total number of S3 bytes sent for this bucket",
		Type:      gaugeMetric,
	}
}

func getBucketUsageTotalBytesMD() MetricDescription {
	return MetricDescription{
		Namespace: bucketMetricNamespace,
		Subsystem: usageSubsystem,

Wie dem auch sei, in jedem der oben genannten Fälle wird FastAPI immer noch asynchron arbeiten und extrem schnell sein.

Wenn Sie jedoch den oben genannten Schritten folgen, können einige Performanz-Optimierungen vorgenommen werden.

    And this path operation will:

    * Send the invoice to the client.
    * Collect the money from the client.
    * Send a notification back to the API user (the external developer), as a callback.
        * At this point is that the API will somehow send a POST request to the
            external API with the notification of the invoice event
            (e.g. "payment successful").
