What is a Placeholder? What is an Expression?

A placeholder is the evaluation of a variable. babelforce uses an "Expression" as the way for you to refer to a variable.

Let's look at an example:

"You have a call from {call.from.number}".

You would be right in expecting this to actually appear something like this once actually evaluated:

"You have a call from +33178979877"

What are the different parts of that thing in curly brackets?

The Expression call.from.number is how to reference the variable that will hold the caller's number on an inbound call. And the curly brackets denote the evaluation of that expression. So {call.from.number} including the brackets is called a Placeholder.
