Error Connecting with Google Calendar: Invalid Client Credentials

[Salmanshu4]

I’m getting an error while integrating Google Calendar with my self-hosted Cal.com instance.

The error suggests missing or invalid client credentials, despite them being configured correctly in the .env file.

Any guidance on resolving this or clarifying the required format would be appreciated.

Hey there, @Salmanshu4! I'm here to help you with any bugs or questions you have. Just give me a shout if you need assistance!

To resolve the "Invalid Client Credentials" error when integrating Google Calendar with your self-hosted Cal.com instance, ensure that the 'client_id', 'client_secret', and 'redirect_uris' are correctly formatted in your .env file. The correct format should be:

• client_id: A non-empty string.
• client_secret: A non-empty string.
• redirect_uris: Either an array of valid URL strings or a single valid URL string that is transformed into an array ^[1][2].

Additionally, check the following common causes of this error:

1. Missing or Incorrect Client ID/Secret: Ensure that the client ID and secret are correctly entered in the .env file.
2. Invalid OAuth Credentials: Verify that the OAuth credentials are valid and correctly configured.
3. Expired or Invalid Access Token: Make sure the access token is valid and not expired.
4. User Not Authorizing the App: Ensure that the app is authorized by the user ^[3].

You might also find it helpful to review similar discussions for additional insights:

• Google Calendar API integration doesn't work because URI Redirect is http ^[4].
• invalid_type in 'client_id','client_secret','redirect_uris': Required ^[5].
