Variables

Variables are used to store any information the bot knows about a user. This can be their preferred language, or the channel they're using, but also information coming from external data sources like, for example, an API. All variables are stored in what is called a user's session.
Sensitive variables - GDPR
Our platform allows you to make sure that some variables are processed differently. This is useful when the conversation between a bot and a user contains sensitive information, such as the user's bank account number.
To make sure variables are not stored in the conversation history, you can click on 'Variables' in the Settings tab. Here you can add a variable to the list of variables by clicking on Create Variable. 
If you put the Sensitive toggle to true, the values of your variable will never be shown in Chatlayer. Instead, any user of our platform will only see a placeholder with the variable name. This information can only be retrieved through an API request.
Incrementing variable counter
If you want to incrementally increase the value of a variable, you can use the following steps:
Define a variable, for example variableName, and give it a numeric value such as 0
At the point in the flow where you want to increment the value of variableName, enter variableName as the variable and {variableName|increment} as the value
This method will increase the value of counter by 1 each time, for example when a specific bot dialog is passed or a button is clicked. How to use this increment functionality in a bot dialog, see this tutorial.
Upper case and lower case variables
Variables and values are case sensitive. For example:
capitalVariable
will be regarded as a separate variable from:
CapitalVariable
The same goes for values. If you check in a Go To if a value for variableX is equal to valueY it will not be triggered if the value for variableX is equal to valuey
You can transform a value from upper case to lower case and vice versa by adding these modifiers to the value name:
{name|toUpperCase}
{name|toLowerCase}
{name|capitalize}
