Understand the statements and conditions

Statements

if

An if statement is a fundamental control structure that allows you to make decisions based on certain conditions. Depending on whether a condition (see below) is true or false, your chatbot will execute one of the blocks of code you make available.

For example, your if statement could check whether a variable contains a value.

for

A for statement, also known as a loop, is a fundamental control structure that allows you to repeat an action multiple times. It's commonly used when you want to perform a task a specific number of times or iterate over a collection of items.

For example, your for statement could create as many cards in a carousel as there are values in your database.

Conditions

starts with / ends with

Checks whether the value inside a variable starts or ends with a specific (set of) character(s). Example:

• {% if custom.get.variable starts with 'H' %}

• {% if custom.get.variable ends with '.com' %}

in / not in

Checks whether the value inside a variable is contained (or not) as part of a series of value. Example:

• {% if custom.get.variable in [1, 2, 3] %}

• {% if custom.get.variable not in [1, 2, 3] %}

is even / is odd

Checks whether the value inside a variable is an even or odd number. Example:

• {% if custom.get.variable is even %}

• {% if custom.get.variable is odd %}

is defined

Checks whether a variable has been declared or assigned a value. Example:

• {% if custom.get.variable is defined %}

is divisible by()

Checks whether the value inside a variable is divisible by another value (number). Example:

• {% if custom.get.variable is divisible by(3) %}

is empty

Checks whether a variable is empty. Example:

• {% if custom.get.variable is empty %}
