Connect Google Meet and Google Calendar

When you need it

• You meet clients on Google Meet and want each booking to get its own Meet link.
• Your team uses Google Calendar and wants bookings to appear there, with busy times blocked.
• You use free Gmail or Google Workspace: both work.

Before you start

• Free Gmail and Google Workspace both work. On free Gmail, Meet calls with three or more people stop at 60 minutes; one-to-one calls are not cut short in this way.
• Your website's address must start with https:// (Google accepts http:// only for localhost).
• No card is needed. Ignore any free-trial offer in Google Cloud.
• This is done once, by the business. Team members never make apps or keys: they only press Connect and allow it.

Step by step

1. 1

   Go to console.cloud.google.com and sign in. Click the project picker (top left), then New project. Name it, such as “Our bookings”, click Create, and make sure it is selected.

   [Screenshot to come] It will show: The New project form with the project name “Our bookings” and the Create button.

2. 2

   Open the menu (☰), then APIs & Services, then Library. Search for Google Calendar API and click Enable.

3. 3

   Open the menu, then Google Auth Platform, then Branding, then Get started. Fill in the App name and User support email, then choose the Audience:

   • Google Workspace: choose Internal. Only people in your own Workspace can connect, there is no warning screen and no 7-day limit.
   • Free Gmail, or team members outside your Workspace: choose External.

   Add your Contact information, agree to the User Data Policy, then Create.

   [Screenshot to come] It will show: The Audience step with Internal and External choices, External selected, and the App name and User support email filled in above.

4. 4

   Open Data Access, click Add or remove scopes and filter by calendar. Tick the scopes ending:

   • calendar.events (create, change and delete booking events, with a Meet link);
   • calendar.freebusy (busy or free only, not event details);
   • calendar.calendarlist.readonly (the list of calendars, so you can choose where bookings go).

   Click Update, then Save.

   [Screenshot to come] It will show: The scopes panel filtered by calendar, with the scopes ending calendar.events, calendar.freebusy and calendar.calendarlist.readonly ticked.

5. 5

   Open Clients, click + Create client and choose Web application. Under Authorised redirect URIs, click + Add URI and paste the address from CaliDiary's Google Meet and Google Calendar section, Redirect address (paste it into your app) (use its Copy button). Click Create.

6. 6

   Copy the Client ID and Client secret into CaliDiary's Client ID and Client secret boxes straight away: Google shows the secret only once.

   [Screenshot to come] It will show: The OAuth client created dialog showing the Client ID and Client secret (both blurred) with their copy buttons, and the Authorised redirect URI behind it.

7. 7

   External apps only: open Audience and click Publish app, so the status is In production. If you leave it in Testing, Google signs everyone out every 7 days.

   [Screenshot to come] It will show: The Audience page with Publishing status, the Publish app button (or the status In production after publishing) and User type External.

8. 8

   In CaliDiary, press Save Google, then Test connection.

   [Screenshot to come] It will show: The Google section with the Redirect address and Copy button, the Client ID and Client secret (Saved: …) boxes, Save Google, Test connection and Remove, and the Connected label after testing.

9. 9

   Sign in the account that makes the business's meetings (the organiser account, such as [email protected]) and choose the business calendar. See The business calendar and the organiser account.

10. 10

    Each person then connects their own calendar on Team and locations → Team → People with Connect Google Calendar, or in My diary, and chooses their account.

    • On an External app, Google shows “Google hasn't verified this app”. That's expected, because it is your own app: click Advanced, then Go to [your app name].
    • Click Allow.

Tips

• There is no separate Meet permission: Meet links are made through Google Calendar events.
• You don't need Google's full app verification for your own business. An unverified app is limited to 100 users, which is plenty for one business.
• Google deletes an OAuth client that hasn't been used for six months. If CaliDiary stops connecting after a long break, check the client still exists.
• Google sometimes renames its menus (Google Auth Platform used to be called the OAuth consent screen). If a name here doesn't match, look for the nearest one.
