Hello @swathisarang98  and @Sohail Khilji ,

Below is my sample script and its output. In the screen shot we can see that two Software value came.

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    try {
        var requestBody = request.body.data;
        var caller = requestBody.caller;
        var category = requestBody.category;
		var shortdescription = requestBody.shortdescription;


        // Insert record into UserTable
        var gr = new GlideRecord('incident');
        gr.initialize();
        gr.setValue('caller_id', caller);
        gr.setValue('category', category);
		gr.setValue('short_description', shortdescription);
        gr.insert();
        response.setStatus(201); // 201 Created
        response.setBody({
            message: "Records created successfully in incident table"
        });
    } catch (ex) {
        response.setStatus(500); // 500 Internal Server Error
        response.setBody({
            error: "An error occurred while processing the request"
        });
    }
})(request, response);
