Constraints Object

Represents the parameter constraints object.

Field	Type	Description
hidden	bool	This constraint is very powerful as it allows vendors to conditionally request information from the client. Since it is about “collecting” information it is obvious that the “hidden“ constraint is available only during the “order” phase. Example: true
required	bool	All defined parameters are mandatory by default, so to make the parameter optional we have to turn on this constraint. Example: false
readonly	bool	If the requirement is to prevent the Client from modifying a value of some parameter, then this constraint can be turned on which will disable the UI components effectively making them not editable. Example: true
capacity	capacityObject	Min and Max number of parameter values. Example: { min: 1, max: 2 }

Capacity Object

Field	Type	Description
min	number	Minimum specifies how many values the user must provide.
max	number	Maximum value shows how many values the user can provide.
