Create Google Calendar Event with File Attachment

Published in: Google Apps Script - Google Calendar

The Google Script will create a new event in the specified Google Calendar and will attach a file from Google Drive into the event.

Google Calendar API only allows file attachments from Google Drive and you can include a maximum of 25 attachment per event. The attachments can be specified either by File ID or by File URL. The Advanced Calendar API should be enabled from your Google Console.

function createEvent() {

  var calendarId = '{{Google Calendar Id}}';

  // April 20, 2016 10:00:00 AM
  var start = new Date(2016, 3, 20, 10, 0, 0);

  // April 20, 2016 10:30:00 AM
  var end = new Date(2016, 3, 20, 10, 30, 0);

  var fileName = "Appraisal Guidlines.pdf";

  // Get the Drive ID of the file attachments
  // Only Google Drive file are support in Google Calendar
  var fileId = DriveApp.getFilesByName(fileName).next().getId();

  var calendarEvent = {
    summary: 'Performance Appraisal',
    description: 'Submit Appraisal Document for March.',
    location: '10 Hanover Square, NY 10005',
    start: {
      dateTime: start.toISOString()

      'fileId': fileId,
      'title': fileName
    attendees: [{
      email: ''
    }, {
      email: ''

  // Set supportsAttachments to true
  // if the calendarEvent object has one or more file attachments
  calendarEvent = Calendar.Events.insert(calendarEvent, calendarId, {
    supportsAttachments: true

  Logger.log('Event with attachment created. Event ID is %s' + calendarEvent.getId());
