Using the system is relatively straight forward once it has been set up.
Swagger is used to document the APIs. Run the application and go to /docs on the correct port, for example, http://localhost:3000/docs. Here you will see all API methods and examples on how to use them.
You can search for .publish( in the code base to find events being published. You can then create an application and queue that listens to the messages being published.
If you are using TypeScript to create your applications, you can use the provided types and constants from the bot-data and bot-manager-data libraries.
An example can be found here for getting the inventory from a bot, using the bot-data types and constants.
