@Madhu Welcome to the Camunda forum :partying_face:

you can configure it similarly groovy script the javascript in script task to validate the JSON using SPIN feature.

Script Format: javascript
ScriptType: Inline script(you can provide the code in Script area while modeling) or External Resource(you can refer from classpath)
ResultVariable: you can store the result of validation in a variable.

Example SPIN api use in Script Task:

var carJson = execution.getVariableTyped("car").getValueSerialized();
var price = S(carJson ).prop("price").numberValue();
execution.setVariable("price", price);
