Google Calendar "The request is missing a valid API key" when using OAuth

I have an OAuth token stored in a database and I am trying to use it to list the calendar events for the calendar. I tried a proof of concept in another language and through that I have verified that my clientID, clientSecret, redirectURL, and refreshTokens all work correctly, but for some reason in Node.js I keep getting a The request is missing a valid API key. error even though the documentation clearly states that I don't need to use an API key if I use an OAuth token.

I am using "googleapis": "^66.0.0"

Any ideas of what I am doing wrong?

The simple as possible code:

const { google } = require('googleapis');

const client = new google.auth.OAuth2(clientID, clientSecret, redirectURL);
client.forceRefreshOnFailure = true;

client.setCredentials({
  refresh_token: '<secret>',
});

const service = google.calendar({ version: 'v3', client });
service.events.list({
  calendarId: '<secret>',
  singleEvents: true,
}, (res, err) => {
  console.log(res)
});

The error message:

  client: OAuth2Client {
    _events: [Object: null prototype] {},
    _eventsCount: 0,

Modification points:

  • In this case, please use the key of auth at google.calendar() like google.calendar({ version: "v3", auth: client }). I think that this is the reason of your error message.
  • And also, about }, (res, err) => { of response values, the 1st argument is the error message. The result value is 2nd argument.

When above points are reflected to your script, it becomes as follows.

Modified script:

const service = google.calendar({ version: "v3", auth: client });  // Modified
service.events.list(
  {
    calendarId: '<secret>',
    singleEvents: true,
  },
  (err, res) => {  // Modified
    if (err) {
      console.log(err);
      return;
    }
    console.log(res.data);
  }
);

Note:

  • In this modification, it supposes that the access token retrieved from your refresh token can be used for retrieving the event list from your calendar. Please be careful this.
