Build Child Nodes · Stella Platform Documentation

Let's continue to follow the tree diagram to build the remaining child nodes and you are very close to completing your first chatbot!

Sample tree diagram

Child Nodes are the nodes that come after the first node and they can be in the second layer, the third layer or even the layers after. Users cannot access any Child Node if they are not on the designated path.

In the above example, "Make a booking" is the Child Node of "Hi, what do you want to do?"" and can only be triggered when user types "1".

Add Child Node

Go to "Node Inspector" and fill in the node details.

Create a trigger that allows user to make a booking. Remember the keyword we ask users to type when they want to make a booking? It's 1. So create a trigger with keyword defined as "1".

Create trigger 1

Create a response to display the question to ask user's name. Select Text as the response type and fill in "What's your name?".

Create new response

Remember to enable "Save User Position" and now you can save the node. You should now have your ask name node created.

Build 3rd-Layer Child Node: Ask Email Address

Create a trigger when users type in their name, that is an Any Text Trigger. However first, you must create a condition. On the right side of the trigger modal, click "+ New Condition".
