proxy and forward the traffic over that connection without presenting a client certificate. Therefore, it is absolutely critical that the waypoint proxy not assume any identity from incoming connections, even if the ztunnel is hairpinning. In other words, all traffic over TLS HBONE tunnels must be considered to be untrusted. From there, traffic is returned to the ztunnel (still over the TLS HBONE tunnel) and forwarded to the destination workload.

The following diagram illustrates the flow of...

from typing import Union

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(
    hidden_query: Union[str, None] = Query(default=None, include_in_schema=False),
):
    if hidden_query:
        return {"hidden_query": hidden_query}
    else:

    "paid": true
}
```

and it would expect a response from that *external API* with a JSON body like:

```JSON
{
    "ok": true
}
```

/// tip

Notice how the callback URL used contains the URL received as a query parameter in `callback_url` (`https://www.external.org/events`) and also the invoice `id` from inside of the JSON body (`2expen51ve`).

///

### Add the callback router

On startup all remote servers must be specified. 
From that individual connections will be spawned to each remote server, 
or incoming requests will be hooked up to the appropriate connection.

To get a connection to a specific server, use `Manager.Connection(host)` to get a connection to the specified host.
From this connection individual requests can be made.
