version: 1.0.0

/register:
post:
summary: Register for an account on this homeserver.
description: |-
This API endpoint uses the [User-Interactive Authentication API](/client-server-api/#user-interactive-authentication-api), except in
the cases where a guest account is being registered.
Register for an account on this homeserver.
There are two kinds of user account:
- `user` accounts. These accounts may use the full API described in this specification.
- `guest` accounts. These accounts may have limited permissions and may not be supported by all servers.
If registration is successful, this endpoint will issue an access token
the client can use to authorize itself in subsequent requests.
If the client does not supply a `device_id`, the server must
auto-generate one.
The server SHOULD register an account with a User ID based on the
`username` provided, if any. Note that the grammar of Matrix User ID
localparts is restricted, so the server MUST either map the provided
`username` onto a `user_id` in a logical manner, or reject any
`username` which does not comply to the grammar with
`M_INVALID_USERNAME`.
Matrix clients MUST NOT assume that localpart of the registered
`user_id` matches the provided `username`.
The returned access token must be associated with the `device_id`
supplied by the client or generated by the server. The server may
invalidate any access token previously associated with that device. See
[Relationship between access tokens and devices](/client-server-api/#relationship-between-access-tokens-and-devices).
When registering a guest account, all parameters in the request body
with the exception of `initial_device_display_name` MUST BE ignored
by the server. The server MUST pick a `device_id` for the account
regardless of input.
Any user ID returned by this API must conform to the grammar given in the
[Matrix specification](/appendices/#user-identifiers).

The basis for the localpart of the desired Matrix ID. If omitted,
the homeserver MUST generate a Matrix ID local part.

device_id:
type: string

ID of the client device. If this does not correspond to a
known client device, a new device will be created. The server
will auto-generate a device_id if this is not specified.
example: GHTYAJCE

A display name to assign to the newly-created device. Ignored
if `device_id` corresponds to a known device.

If true, an `access_token` and `device_id` should not be
returned from this call, therefore preventing an automatic
login. Defaults to false.

the access token has expired a new access token can be
obtained by using the provided refresh token. If no
refresh token is provided, the client will need to re-log in
to obtain a new access token. If not given, the client can
assume that the access token will not expire.
Omitted if the `inhibit_login` option is true.

home_server:

The server_name of the homeserver on which the account has

it. Note also that `homeserver` is not spelt this way.

* `M_INVALID_USERNAME` : The desired user ID is not a valid user name.
* `M_EXCLUSIVE` : The desired user ID is in the exclusive namespace
claimed by an application service.
These errors may be returned at any stage of the registration process,
including after authentication if the requested user ID was registered
whilst the client was performing authentication.
Homeservers MUST perform the relevant checks and return these codes before
performing User-Interactive Authentication, although they may also return
them after authentication is completed if, for example, the requested user ID
was registered whilst the client was performing authentication.

An access token should be submitted to this endpoint if the client has
an active session.

valid access token is provided. The homeserver SHOULD NOT revoke the
access token provided in the request. Whether other access tokens for

If not provided, the homeserver MUST use the `id_server`

it must return an `id_server_unbind_result` of

Whether the user would like their content to be erased as

Erasure means that any users (or servers) which join the
room after the erasure request are served redacted copies of
the events sent by this account. Users which had visibility
on those events prior to the erasure are still able to see
unredacted copies. No redactions are sent and the erasure
request is not shared over federation, so other servers
might still serve unredacted copies.
The server should additionally erase any non-event data
associated with the user, such as [account data](/client-server-api/#client-config)
and [contact 3PIDs](/client-server-api/#adding-account-administrative-contact-information).
Defaults to `false` if not present.

An indicator as to whether or not the homeserver was able to unbind
the user's 3PIDs from the identity server(s). `success` indicates
that all identifiers have been unbound from the identity server while
`no-support` indicates that one or more identifiers failed to unbind
due to the identity server refusing the request or the homeserver
being unable to determine an identity server to unbind from. This

summary: Checks to see if a username is available on the server.
description: |-
Checks to see if a username is available, and valid, for the server.
The server should check to ensure that, at the time of the request, the
username requested is available for use. This includes verifying that an
application service has not claimed the username and that the username
fits the server's desired requirements (for example, a server could dictate
that it does not permit usernames with underscores).
Matrix clients may wish to use this API prior to attempting registration,
however the clients must also be aware that using this API does not normally
reserve the username. This can mean that the username becomes unavailable
between checking its availability and attempting to register it.
