This example shows the report export service. First, check a report file in the Reports folder:

public HttpResponseMessage Get(string id, string reportName)
{
	// Check a report file in the 'Reports' folder
	var reportFilePath = Path.Combine(HttpRuntime.AppDomainAppPath, "Reports", reportName + ".mrt");
	if (!File.Exists(reportFilePath))
		reportFilePath = Path.Combine(HttpRuntime.AppDomainAppPath, "Reports", reportName + ".mdc");
	if (!File.Exists(reportFilePath))
		return GetHttpResponseMessage("The report file does not exist!");
				
...

Next, load and render the report template:

...

	// Load and render the report template
	var report = new StiReport();
	if (reportFilePath.EndsWith(".mrt"))
	{
		report.Load(reportFilePath);
		report.Render(false);
	}
	// Load the rendered report document
	else
		report.LoadDocument(reportFilePath);
				
...

After that, use ExportDocument() method to export document to necessary format:

...

	MemoryStream stream;
	HttpResponseMessage result;

	switch (id)
	{
		// Export to PDF
		case "pdf":
			var pdfSettings = new StiPdfExportSettings();
			// settings, if required

			stream = new MemoryStream();
			report.ExportDocument(StiExportFormat.Pdf, stream, pdfSettings);
			result = GetHttpResponseMessage(stream.ToArray(), "application/pdf");
			stream.Close();
			return result;

		// Export to Excel 2007+
		case "excel":
			var excelSettings = new StiExcel2007ExportSettings();
			// settings, if required

			stream = new MemoryStream();
			report.ExportDocument(StiExportFormat.Excel2007, stream, excelSettings);
			result = GetHttpResponseMessage(stream.ToArray(), "application/vnd.ms-excel");
			stream.Close();
			return result;

		// Export to HTML
		case "html":
			var htmlSettings = new StiHtmlExportSettings();
			// settings, if required

			stream = new MemoryStream();
			report.ExportDocument(StiExportFormat.Html, stream, htmlSettings);
			result = GetHttpResponseMessage(stream.ToArray(), "text/html");
			stream.Close();
			return result;

		default:
			return GetHttpResponseMessage($"The export format [{id}] is not supported!");
	}
}
