When you need to send data from a client (let's say, a browser) to your API, you send it as a **request body**.

A **request** body is data sent by the client to your API. A **response** body is the data your API sends to the client.

## 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.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:

                        logger.debug("Sent {} to {}.", body, url);
                    }
                } else {
                    logger.warn("Failed to send {} to {}. HTTP Status is {}. {}", body, url, response.getHttpStatusCode(),
                            response.getContentAsString());
                }
            } catch (final IOException e) {
                logger.warn("Failed to send {} to {}.", body, url, e);
