 * application data - do we need a dictionary for our applications like Apple does. We could easily
 * hook into this and this is the model we need to follow - how many of our REST services do not map

    * Por lo tanto, el manejo de **certificados y encriptación** se realiza **antes de HTTP**.
* **TCP no sabe acerca de "dominios"**. Solo sobre direcciones IP.
    * La información sobre el **dominio específico** solicitado va en los **datos HTTP**.
* Los **certificados HTTPS** "certifican" un **cierto dominio**, pero el protocolo y la encriptación ocurren a nivel de TCP, **antes de saber** con cuál dominio se está tratando.

But possibly the most important part of the callback is making sure that your API user (the external developer) implements the *external API* correctly, according to the data that *your API* is going to send in the request body of the callback, etc.

So, what we will do next is add the code to document how that *external API* should look like to receive the callback from *your API*.

        val localRepository = bucket("${prefix}TestLocalRepository", "Declare a local repository required as input data for the tests (e.g. :tooling-api)")
        val normalizedDistribution = bucket("${prefix}TestNormalizedDistribution", "Declare a normalized distribution (bin distribution without timestamp in version) to be used in tests")

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

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