Schedule Google Meet Using HTML and JavaScript.

In order to schedule a Google Meet with the attendees, first you need to create a event in your calendar and share with all the attendees.

For the same I had previously wrote a blog on how to create a event using HTML and JavaScript. Refer to this Blog.

In this blog I will guide you to create a website using simple HTML and JavaScript through which you can automatically schedule a Google Meet in your calendar and also share the same with the attendees.

Creating an Event in Google Calendar.

This is a very short explanation of creating an event. To read a brief explanation go here

  1. Enable Google Calendar API
  2. Create API key and Client ID
  3. Configure your OAuth Consent Screen and Publish your app
  4. Add the following code in your index.html.

    <!DOCTYPE html>
    <title>Google Calendar API Quickstart</title>
     <meta charset="utf-8" />
       form {
         margin: 10px;
       fieldset {
         width: fit-content;
       input {
         margin-block: 10px;
    <!--Add buttons to initiate auth sequence and sign out-->
    <button id="authorize_button" onclick="handleAuthClick()">Authorize</button>
    <button id="signout_button" onclick="handleSignoutClick()">Sign Out</button>
    <br />
    <form id="event_form">
        <input type="text" name="title" id="title" placeholder="Add Title" class="input-title" />
        <br />
        <textarea type="text" name="desc" id="desc" placeholder="Add Descreption" class="input-title"></textarea>
        <br />
        <input type="date" name="date" id="date" />
          <label>Start Time</label>
          <input type="time" name="st" id="st" />
          <label>End Time</label>
          <input type="time" name="et" id="et" />
        <button type="button" onclick="addEvent()">Schedule</button>
    <pre id="content" style="white-space: pre-wrap;"></pre>
    <script src="./index.js" type="text/javascript"></script>
    <script async defer src="" onload="gapiLoaded()"></script>
    <script async defer src="" onload="gisLoaded()"></script>
  5. Add the following code in your index.js and set your API key and Client Id.

// TODO(developer): Set to client ID and API key from the Developer Console
const API_KEY = "<YOUR_API_KEY>";

// Discovery doc URL for APIs used by the quickstart

// Authorization scopes required by the API; multiple scopes can be
// included, separated by spaces.
const SCOPES = "";

let tokenClient;
let gapiInited = false;
let gisInited = false;

document.getElementById("authorize_button").style.visibility = "hidden";
document.getElementById("signout_button").style.visibility = "hidden";
document.getElementById("event_form").style.visibility = "hidden";

function gapiLoaded() {
  gapi.load("client", initializeGapiClient);

async function initializeGapiClient() {
  await gapi.client.init({
    apiKey: API_KEY,
    discoveryDocs: [DISCOVERY_DOC]
  gapiInited = true;

function gisLoaded() {
  tokenClient = google.accounts.oauth2.initTokenClient({
    client_id: CLIENT_ID,
    scope: SCOPES,
    callback: "" // defined later
  gisInited = true;

function maybeEnableButtons() {
  if (gapiInited && gisInited) {
    document.getElementById("authorize_button").style.visibility = "visible";

function handleAuthClick() {
  tokenClient.callback = async resp => {
    if (resp.error !== undefined) {
      throw resp;
    document.getElementById("signout_button").style.visibility = "visible";
    document.getElementById("event_form").style.visibility = "visible";
    document.getElementById("authorize_button").innerText = "Refresh";
    await listUpcomingEvents();

  if (gapi.client.getToken() === null) {
    // Prompt the user to select a Google Account and ask for consent to share their data
    // when establishing a new session.
    tokenClient.requestAccessToken({ prompt: "consent" });
  } else {
    // Skip display of account chooser and consent dialog for an existing session.
    tokenClient.requestAccessToken({ prompt: "" });

function handleSignoutClick() {
  const token = gapi.client.getToken();
  if (token !== null) {
    document.getElementById("content").innerText = "";
    document.getElementById("authorize_button").innerText = "Authorize";
    document.getElementById("signout_button").style.visibility = "hidden";
    document.getElementById("event_form").style.visibility = "hidden";

async function listUpcomingEvents() {
  let response;
  try {
    const request = {
      calendarId: "primary",
      timeMin: new Date().toISOString(),
      showDeleted: false,
      singleEvents: true,
      maxResults: 10,
      orderBy: "startTime"
    response = await;
  } catch (err) {
    document.getElementById("content").innerText = err.message;

  const events = response.result.items;
  if (!events || events.length == 0) {
    document.getElementById("content").innerText = "No events found.";
  // Flatten to string to display
  const output = events.reduce(
    (str, event) =>
      `${str}${event.summary} (${event.start.dateTime ||})\n`,
  document.getElementById("content").innerText = output;

const addEvent = () => {
  // Refer to the JavaScript quickstart on how to setup the environment:
  // Change the scope to '' and delete any
  // stored credentials.

  const title = document.getElementById("title").value;
  const desc = document.getElementById("desc").value;
  const date = document.getElementById("date").value;
  const start = document.getElementById("st").value;
  const end = document.getElementById("et").value;
  var ISOstartdate = "";

  const startTime = new Date(date + "," + start).toISOString();
  const endTime = new Date(date + "," + end).toISOString();

  var event = {
    summary: title,
    location: "Google Meet",
    description: desc,
    start: {
      dateTime: startTime,
      timeZone: "America/Los_Angeles"
    end: {
      dateTime: endTime,
      timeZone: "America/Los_Angeles"
    recurrence: ["RRULE:FREQ=DAILY;COUNT=2"],
    attendees: [{ email: "" }, { email: "" }],
    reminders: {
      useDefault: false,
      overrides: [
        { method: "email", minutes: 24 * 60 },
        { method: "popup", minutes: 10 }

  var request ={
    calendarId: "primary",
    resource: event

  request.execute(function(event) {
Enter fullscreen mode Exit fullscreen mode

Schedule Google Meet

You can associate calendar events with Google Meet conferences to allow your users to meet remotely via a phone call or a video call.

The conferenceData field can be used to read, copy, and clear existing conference details; it can also be used to request generation of new conferences.

To create schedule a Google Meet while creating the calendar event we require

  1. The requestId which can be a random string.
  2. The calendarId of the event creator that we will get from the responce after the event is created.
  3. The eventId which is a combination of the Id and the start date of the event created.

We need to create a new function within addEvent function in our index.js

 async function createMeet(calendarId, eid) {
    const eventPatch = {
      conferenceData: {
        createRequest: { requestId: "7qxalsvy0e" }

        calendarId: calendarId,
        eventId: eid, // id + startdate.toISOString()
        resource: eventPatch,
        sendNotifications: true,
        conferenceDataVersion: 1
      .execute(function(event) {
        console.log("Conference created for event: %s", event.htmlLink);
Enter fullscreen mode Exit fullscreen mode

Now we need to call the createMeet function in request.execute method inside the addEvent function in our index.js add pass calenderId and eventId as the parameter. Therefore replace the request.execute method with this code.

request.execute(function(event) {
    var ISOstartdate = new Date(event.start.dateTime).toISOString();
    var eid = + "_" + ISOstartdate.replace(/[:-]/g, "").replace(".000Z", "Z");
    var calendarId =;
    createMeet(calendarId, eid);
Enter fullscreen mode Exit fullscreen mode

I have pushed my code in this GitHub Repo on gmeet branch you can fork it and add your innovations or if you want to contribute to this repository you can create a pull request.
