- User ID
- HS Credentials
Output:
- Profile info
- Whether the user exists.
Side effects:
- User is created on the HS if this response 200s.
- User is created on the HS by the AS via CS APIs during the processing of this request.
API called when:
- HS receives an event for an unknown user ID in the AS's namespace, e.g. an
invite event to a room.
Notes:
- The created user will have their profile info set based on the output.
- When the AS receives this request, if the user exists, it must create the user via
the CS API.
- It can also set arbitrary information about the user (e.g. display name, join rooms, etc)
using the CS API.
- When this setup is complete, the AS should respond to the HS request. This means the AS
blocks the HS until the user is created.
- This is deemed more flexible than alternative methods (e.g. returning a JSON blob with the
user's display name and get the HS to provision the user).
Retry notes:
- The home server cannot respond to the client's request until the response to
this API is obtained from the AS.

Room Alias Query ``[Draft]``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
@ -155,12 +157,20 @@ Output:
- The current state events for the room if any.
- The message events for the room if any.
Side effects:
- A new room will be created with the alias input if this response 200s.
- Room is created on the HS by the AS via CS APIs during the processing of
this request.
API called when:
- HS receives an event to join a room alias in the AS's namespace.
Notes:
- This can be thought of as an ``initialSync`` but for a 3P networked room,
which is lazily loaded when a matrix user tries to join the room.
- When the AS receives this request, if the room exists, it must create the room via
the CS API.
- It can also set arbitrary information about the room (e.g. name, topic, etc)
using the CS API.
- When this setup is complete, the AS should respond to the HS request. This means the AS
blocks the HS until the room is created and configured.
- This is deemed more flexible than alternative methods (e.g. returning an initial sync
style JSON blob and get the HS to provision the room). It also means that the AS knows
the room ID -> alias mapping.
Retry notes:
- The home server cannot respond to the client's request until the response to
this API is obtained from the AS.

Pushing ``[Draft]``
~~~~~~~~~~~~~~~~~~~
@ -345,13 +331,6 @@ Examples
--------
.. NOTE::
- User/Alias namespaces are subject to change depending on ID conventions.
- Should home servers by default generate fixed room IDs which match the room
alias? Otherwise, you need to tell the AS that room alias X matches room ID
Y so when the home server pushes events with room ID Y the AS knows which
room that is. Alternatively, do we expect ASes to query the HS via the room
alias APIs just like clients do? This doesn't get us the reverse mapping
though which is what we really want when events are pushed to the AS. Maybe
a special room_id_to_alias event poke is pushed to the AS?

"!irc.freenode.net/#matrix:hsdomain.com" with normal state events
(e.g. m.room.create). join_rules can be overridden by the AS if supplied in
"state".

"@irc.freenode.net/Bob:hsdomain.com" in AS namespace, so queries AS.
