A Checkout configuration has a number of parameters activated by default and the option to activate additional predefined parameters as well as create custom parameters. Parameters can be used to set up conditions in the Rule Engine. 

If a parameter is used in a condition and you do not set a default value, the parameter value must be set in the API call. Parameters connected to the sender are set automatically, for example, from_postal_code and from_country.

• Activate a parameter and set a default value
