# Warnings And Failures<no value>

{{< callout context="caution" title="IMPORTANT!" icon="outline/alert-triangle" >}}

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-index/).

{{< /callout >}}

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