This example shows how to supply custom headers for JSON Database. First, create the dashboard viewer and a new dashboard instance:

<script type="text/javascript">
	// Create the dashboard viewer with default options
	var viewer = new Stimulsoft.Viewer.StiViewer(null, "StiViewer", false);
	// Create a new dashboard instance
	var report = Stimulsoft.Report.StiReport.createNewDashboard();

...

Then, in onBeginProcessData event handler add custom HTTP headers:

...

	report.onBeginProcessData = function (args) {
		if (
			args.database === "JSON" &&
			args.command === "GetData" && 
			args.pathData && args.pathData.indexOf("/dashboard/ProtectedDemo.json") >= 0
		) {
		// Add custom header to pass through backend server protection
		args.headers.push({key: "X-Auth-Token", value: "*YOUR TOKEN*"});
	}
};
	
...

After that, load dashboard from URL and assign it to the viewer:

...
		
	// Load dashboard from url
	report.loadFile("../dashboard/DBSsimp.mrt");
	// Assign dashboard to the viewer
	viewer.report = report;
	// Show the dashboard viewer in this place
	viewer.renderHtml();	
</script>
