Before You Begin

Global fallback will occur if a user reply node is configured and an invalid response is triggered by the user after all local fallbacks are exhausted.

Overview

As implied by its name, a global fallback can be triggered on any user reply node in case of an invalid user response. You can repeat the parent bot reply for the invalid response.

Fallback Settings

A global fallback setting is important in such cases when the user's response does not match any of the expected answers and there is no local fallback set. With a fallback, the bot can provide a default response or ask the user to rephrase their answer. This ensures that the conversation does not come to a halt and the user does not get frustrated with the bot. A well-designed fallback setting can help maintain a positive user experience and keep the conversation going in the right direction.

Note that if a node has a local fallback set up, it will take priority over the global fallback settings. For more information, see handle invalid user reply.
