Constraint​

Example​

{
    "contextName": "appName",
    "operator": "STR_CONTAINS",
    "values": [],
    "inverted": false,
    "caseInsensitive": false
}

Description​

values and value

Some constraint operators only support single values. If a constraint uses one of these operators, the payload will contain a value property with the correct value. However, for backwards compatibility reasons, the payload will also contain a values property. If the operator accepts multiple values, the value property will not be present. Visit the strategy constraints documentation for more information on what operators support what number of values.

PropertyTypeRequiredDescriptionExample value
contextNamestringYesThe name of the context field targeted by the constraint."myContextField"
operatorstring, the name of one of the constraint operatorsYesThe operator to apply to the context field."DATE_BEFORE"
valuesa list of stringsYesThe list of values to apply the constraint operator to.["value a", "value b"]
valuestringNoThe value to apply the constraint operator to."15"
invertedbooleanNoWhether the result of the constraint will be negated or not.false
caseInsensitiveboolean stringNoWhether the constraint operator is case sensitive or not. Only applies to some string-based operators.false
