        Gets a list of the third party identifiers that the homeserver has
        associated with the user's account.

        This is *not* the same as the list of third party identifiers bound to
        the user's Matrix ID in identity servers.

        Identifiers in this list may be used by the homeserver as, for example,
        identifiers that it will accept to reset the user's account password.

        and ``/3pid/bind`` endpoints.

        .. Note::
           Previously this endpoint supported a ``bind`` parameter. This parameter
           has been removed, making this endpoint behave as though it was ``false``.
           This results in this endpoint being an equivalent to ``/3pid/bind`` rather

        already associated with an account on this homeserver. This API should
        be used to request validation tokens when adding an email address to an
        account. This API's parameters and response are identical to that of
        the |/register/email/requestToken|_ endpoint. The homeserver should validate
        the email itself, either by sending a validation email itself or by using
        a service it has control over.
