Hi,
You can add following code into the On Load event of the first slide:
if (!prez.initReport) {
prez.initReport = true;
var fOldReport = prez.formatReportData;
prez.formatReportData = function(data, format) {
var result = fOldReport.call(this, data, format);
var isObject = typeof result == 'object';
if (!isObject) {
try {
var json = JSON.parse(result);
result = json;
} catch (ex) {
alert('The report is not a valid JSON');
return result;
}
}
result['customId'] = prez.variable('variable_name'); //Replace this line
return isObject ? result : JSON.stringify(result);
}
}
Regards,
