Getting 'unknown sender' notification when creating google calender event via service account

[mster429]

const auth = new GoogleAuth({
      scopes: [
        'https://www.googleapis.com/auth/calendar',
        'https://www.googleapis.com/auth/calendar.events'
      ],
      keyFile: './src/serviceaccount.json',
      clientOptions: {
        subject: '[email protected]'
      }
    });

    const calendar = google.calendar({ version: 'v3', auth: auth });

    const apiResponse = await calendar.events.insert({
      calendarId: "[email protected]",
      conferenceDataVersion: 1,
      requestBody: {
        start: {
          dateTime: "2024-10-10T08:00:00+09:00",
        },
        end: {
          dateTime: "2024-10-10T08:30:00+09:00",
        },
        attendees: [{ email: "[email protected]" }, { email: "[email protected]" }],
        summary: 'Test Event',
        description: 'Test Event created',
        guestsCanInviteOthers: true,
        conferenceData: {
          createRequest: {
            requestId: randomUUID(),
            conferenceSolutionKey: {
              type: 'hangoutsMeet'
            }
          }
        },
        reminders: {
          useDefault: false,
          overrides: [],
        },
        guestsCanModify: true,
        visibility: 'default',
      }
    });

I am using the above code to create a calender event using google calender api via google service account. sendUpdates parameter is false so that I don't get any notification via google about the event creation. But when I try this only the first time I am getting the below notification from google and i need to suppress/ disable it and i need help to get this resolved.

Thanks in advance

Can you try this one:

const { google } = require('googleapis');
const { GoogleAuth } = require('google-auth-library');
const { randomUUID } = require('crypto');

const auth = new GoogleAuth({
  scopes: [
    'https://www.googleapis.com/auth/calendar',
    'https://www.googleapis.com/auth/calendar.events'
  ],
  keyFile: './src/serviceaccount.json',
  clientOptions: {
    subject: '[email protected]' // User under which the service account will operate
  }
});

const calendar = google.calendar({ version: 'v3', auth: auth });

const apiResponse = await calendar.events.insert({
  calendarId: "[email protected]",
  conferenceDataVersion: 1,
  requestBody: {
    start: {
      dateTime: "2024-10-10T08:00:00+09:00",
    },
    end: {
      dateTime: "2024-10-10T08:30:00+09:00",
    },
    attendees: [{ email: "[email protected]" }, { email: "[email protected]" }],
    summary: 'Test Event',
    description: 'Test Event created',
    guestsCanInviteOthers: true,
    conferenceData: {
      createRequest: {
        requestId: randomUUID(),
        conferenceSolutionKey: {
          type: 'hangoutsMeet'
        }
      }
    },
    reminders: {
      useDefault: false,
      overrides: [],
    },
    guestsCanModify: true,
    visibility: 'default',
  },
  sendUpdates: 'none' // Add this line to suppress notifications
});

Hi @Nondukishor
This is what was on the official documentation

Because we are heavily using the sync webhooks we are not going to use this option
