User Input helps to collect text messages sent by users, images, and all other input formats supported by Facebook Messenger for further use.
User Input saves the data in an existing user attribute or creates a new attribute in case it does not exist yet.
The bot asks the questions, grab the data from their answers, save it to user attributes and you can reuse those user input values.
