Connect Google Calendar (and get past 'this app isn't verified')

Connecting Google Calendar lets KM Hub see your real availability, so every quote and hold is checked against dates you are actually free and quotes never double-book. The basic connection is read-only: KM Hub never changes anything in your Google Calendar unless you explicitly turn on two-way sync with write access.

Connect your Google account

1. Go to Settings > Connect > Integrations and scroll to the Google Calendar card.
2. Click Connect Google Calendar.
3. Sign in with the Google account that owns the calendar you want to sync and grant access. The default connection is read-only access to your calendars.

Getting past "Google hasn't verified this app"

During sign-in, Google may show a warning screen that says the app isn't verified. This appears while an app is going through Google's review process and does not change what KM Hub can access. To continue:

1. On the warning screen, click Advanced.
2. Click the Go to link at the bottom of the expanded text.
3. Review the requested permissions and click Allow (or Continue).

You only see this screen once, during the initial connection.

Choose calendars and import your events

1. Once connected, use the Calendars to import checklist to pick which of your Google calendars KM Hub should pull from, then click Save selection.
2. Click Import events. Events with an external guest become bookings linked to that client; everything else lands as an inquiry you can triage.
3. Come back anytime and click Sync now to pull new events. Already-imported events are never duplicated.

Turn on two-way sync (push bookings to Google)

By default the sync is Import only. If you also want your confirmed KM Hub bookings to appear in Google Calendar:

1. In the Google Calendar card, switch the sync radio from Import only to Two-way.
2. Click Connect with write access and approve the extra permission in Google. This is the only mode where KM Hub writes to your calendar.
3. Pick the target calendar in the Push bookings to select.
4. Click Push bookings to Google now to push immediately instead of waiting for the next sync.

Outlook and Microsoft 365

The Outlook / Microsoft 365 card sits right below Google Calendar and works the same way: connect your Microsoft account, choose a default calendar, and optionally enable two-way sync to push confirmed bookings back to Outlook. If the card shows a "not configured" state, the Microsoft connection isn't set up on the server side yet - contact support and we'll sort it out.

Disconnecting

Click Disconnect in the calendar card at any time. Events already imported into KM Hub stay where they are; KM Hub simply stops syncing.
