Prop

If you have been developing websites, you probably come across this word. Here, Props are custom variables that you can use however you'd like - to store data in the user session under that variable.

The engine keeps track of the user session props internally.

Defining a prop

To define a prop on a particular template, provide the prop attribute with your defined variable name

"ASK_NAME_STAGE":
  type: text
  prop: username
  message: "What is your name?"
  routes:
    "re:\\w+": "ASK_AGE_STAGE"

In the above template, when user provides a response, it will be saved in the user session props under the key username

You can then access this user session data in your bot business logic.
