Fallback

Fallback is a special type that is used to define the id of the row from which the conversation will continue if the bot does not know how to respond. This happens when a user’s message doesn’t match any button or doesn’t fall under any FAQ question either. In such a case, Goto column of the fallback type will determine from where the conversation will continue.

Example:

IDTypeTextGoto
6.1DialogueSorry, I did not understand.1
fallback6

Recommended:
Fallback can be used to connect to a human if the bot couldn’t understand any input from the user.
