In this tutorial you will learn about the Message Node, what it does and how to use and its Settings
1. What it does
Adds a plain text or SSML message, which will be passed to the user at the end. Alexa or Google assistant will read out the message to the user
You can add more than one version of message, out of which only one will be selected randomly.
Handlebar-like syntax can be used to insert values of variables like from Project Data Store, by using {{msg.govocal.dataStore.config.WelcomeMessage}}
<speak></speak> tags.
2. How to use
Use this Node whenever you want to respond the user with some message.
- When using Message Node with Card Node(as shown above), Alexa will read out the message in Message Node along with displaying the card to the user.
- Make sure to add Respond Node, in order to send the response to the user
