Campaign
A campaign is a predefined conversation flow that is delivered to users. The conceptual structure of a campaign resembles that of a directed acyclic graph, where each node represents a message in the conversation. A message node can have multiple edges, each leading to another node, that represent preset responses to the message.
The menu is a special campaign that is always accessible to users by sending "Menu" to the chatbot. It responds with a list of options that the user can use to access more information.
The onboarding campaign is the campaign that users interact with when they first sign up to use the chatbot. It asks them a series of questions about their content preferences and helps to demonstrate and explain how the service works.
