Token Variables - along with the [Gauge API](../gauge-api/) - have been deprecated in Microsoft Flight Simulator 2024 in favour of the new [Vars API](../../vars-api/vars-api/) and [Event API](../../event-api/event-api/), which work with the more extensive and supported [Simulation Variables](../../../simvars/simulation-variables/) and [Key Events](../../../key-events/key-events/).

{{< /callout >}}

This page lists the available **engine** [Token Variables](token-variables/) for use when creating gauges using {{< glossterm >}}wasm{{< /glossterm >}} / C++.
