Create a Global Node

Now you can see your first node in the workspace, how about on your testing chatbot? In this section, we will teach you to create another type of node: Global Node. It allows you to trigger the same node at any point of your conversation flow.

Once added to Channel, Global Node is often used as a "door" to kickstart a conversation. For example, we will trigger the global node with the Ice Breakers feature in Instagram messaging.

Without a Global Node, no one can ever kick-start your chatbot.

Expected Outcome

You should also be able to trigger the first node on your testing chatbot in two ways: by clicking the Ice Breakers button.
