User variable

Available in Classic and VPC

A chatbot can get meaningful information through conversations with users. Among these pieces of information, some should only be temporarily retained to respond to an answer, while others may be stored and used repeatedly throughout the duration of a conversation session. The information obtained through the conversation with the user during a conversation session is managed as variables.
