Answers your bot already knows

There is a lot that your bot already knows about a person you are chatting with. These are published as Global variables that you can call like other variables you define within the chat. Besides knowing more about the user’s details, you can use the same variables within your chatflow dialogue or pass this to webhook for further transactions. Here is a list of these global variables:
