Keywords are messages that are set-up to automatically respond to a predetermined word or set of words that a user might key in. They are words that the user is instructed to type or could type and to which they will receive an automatic message you have chosen.
Messages that your bot receives that do not match any keywords are shown in the Ignored Messages section of the platform. A user who has typed one of these messages should be shown the 'Default Reply' message that you set up in case this happens.
