### `Optional`session[](#session)

session?: boolean

Specifies whether the geocoding request runs with a session logic. A "session" is started at the initialization of the SDK and finished when the browser page is being closed or refreshed. When this option is enabled, extra URL param `mtsid` is added to queries to the MapTiler Cloud API. This allows MapTiler to enable "session based billing".

Default: value of this option in global config (which is `true` by default).
