Getting Your Access Token

Google Calendar requires OAuth 2.0 access tokens (not API keys). The easiest way to get one for testing:

1. Go to https://developers.google.com/oauthplayground/

2. Select "Google Calendar API v3" and check the scopes you need

3. Click "Authorize APIs" and sign in with your Google account

4. Click "Exchange authorization code for tokens"

5. Copy the access token (expires after 1 hour)
