ImpostorHQ is a plugin for the Impostor private Among Us server. It offers a way to monitor and administer the server remotely. It also provides an easy player chat interface for making command handlers.
Once the plugin is installed, you must run the server once. A configuration file will be created. In that configuration file, you can change your API keys, add more, remove keys, and change the ports. There are 3 parts to this plugin : the player chat command handler, which handles in-game commands, the web API server, which handles communication between dashboards and the server, and the HTTP server, which loads the client/dashboard onto browsers.
There also is an extension included, which handles bans. It is a good example of how to integrate with the API: sending commands to the dashboard, receiving them, overriding the command handler, and actually executing logic.
