 | `is_dm` | `bool` | No | Flag which only returns rooms present (or not) in the DM section of account data.<br/><br/> If unset, both DM rooms and non-DM rooms are returned. If False, only non-DM rooms are returned. If True, only DM rooms are returned. |
 | `spaces` | `[string]` | No | Filter the room based on the space they belong to according to `m.space.child` state events. <br/><br/> If multiple spaces are present, a room can be part of any one of the listed spaces (OR'd). The server will inspect the `m.space.child` state events for the JOINED space room IDs given. Servers MUST NOT navigate subspaces. It is up to the client to give a complete list of spaces to navigate. Only rooms directly mentioned as `m.space.child` events in these spaces will be returned. Unknown spaces or spaces the user is not joined to will be ignored. |
 | `is_encrypted` | `bool` | No | Flag which only returns rooms which have an `m.room.encryption` state event. <br/><br/> If unset, both encrypted and unencrypted rooms are returned. If `false`, only unencrypted rooms are returned. If `True`, only encrypted rooms are returned. |
-| `is_invite` | `bool` | No | Flag which only returns rooms the user is currently invited to. <br/><br/> If unset, both invited and joined rooms are returned. If `False`, no invited rooms are returned. If `True`, only invited rooms are returned. |
+| `is_invite` | `bool` | No | Flag which only returns rooms the user is currently invited to. <br/><br/> If unset, both invited and joined rooms are returned. If `false`, no invited rooms are returned. If `true`, only invited rooms are returned. |
 | `room_types` | `[string \| null]` | No | If specified, only rooms where the `m.room.create` event has a `type` matching one of the strings in this array will be returned. <br/><br/> If this field is unset, all rooms are returned regardless of type. This can be used to get the initial set of spaces for an account. For rooms which do not have a room type, use `null` to include them. |
 | `not_room_types` | `[string \| null]` | No | Same as `room_types` but inverted.<br/><br/> This can be used to filter out spaces from the room list. If a type is in both `room_types` and `not_room_types`, then `not_room_types` wins and they are not included in the result. |
 | `tags` | `[string]` | No | Filter the room based on its room tags.<br/><br/> If multiple tags are  present, a room can have any one of the listed tags (OR'd). |
