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 ``username``\s which do 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`_. 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.html#user-identifiers>`_. operationId: register parameters: - in: query name: kind type: string # swagger-UI overrides the default with the example, so better make the # example the default. x-example: user required: false default: user enum: - guest - user description: The kind of account to register.

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. examples: application/json: { "errcode": "M_USER_IN_USE", "error": "Desired user ID is already taken." } schema: "$ref": "definitions/errors/error.yaml" 401: description: |- The homeserver requires additional authentication information. schema: "$ref": "definitions/auth_response.yaml" 403: description: |- The homeserver does not permit registering the account.
