This will primarily cover error replies, and only those generated by the
same Prosody instance using the `origin.reply()` method.

+Replies to other kinds of stanzas that are generated by the same Prosody
+instance *MAY* be returned in the HTTP response. Replies from other
+entities (connected clients or remote servers) will not be returned, but
+can be forwarded via the callback API described in the next section.

 ## Receiving stanzas
 
 TL;DR: Set this webhook callback URL, get XML `POST`-ed there.
