## Google Calendar

Bookings are added to Google Calendar as they're made, and moved or removed with them. And busy times in that calendar (a dentist appointment, a day out) aren't offered for booking.

Each staff member can connect their own calendar; the **business's calendar** takes bookings without a staff member, and those of staff members who haven't connected one.

### Set up the Google client (once)

Bookline Pro uses your own Google Cloud project, so nothing passes through anyone else's servers.

1. In the [Google Cloud console](https://console.cloud.google.com/), create a project (or pick one).
2. **APIs & Services → Library**: turn on the **Google Calendar API**.
3. **APIs & Services → OAuth consent screen**: set it up (External, with your email). While it's in "Testing", add the Google accounts you'll connect as test users.
4. **APIs & Services → Credentials → Create credentials → OAuth client ID**, type **Web application**. Under **Authorized redirect URIs**, add the **Redirect URI** shown on **Bookline → Settings → Calendar sync**.
5. Copy the **Client ID** and **Client secret** into the Calendar sync tab, and save.

### Connect a calendar

- The business's: **Connect Google Calendar** on the Calendar sync tab.
- A staff member's: **Connect Google Calendar** in the **Calendar sync** box on their page.

Sign in to Google and allow access. Bookings go to the account's main calendar.

### What syncs

- New, moved, changed and cancelled bookings, within moments, in the background.
- Events Bookline adds show as "free" in Google, so they don't block bookings themselves.
- Busy times are checked every five minutes. Untick **Don't offer times that are busy** to stop that.
- If Google can't be reached, booking goes on as usual, and the booking's history says what went wrong.

**Disconnect** removes the connection (and Bookline's access in Google).

## Calendar feeds

Each staff member, and the business, has a private calendar address: every booking from 30 days ago to a year ahead. Subscribe to it in Outlook, Apple Calendar or Google Calendar (**From URL**). Calendar apps refresh subscriptions on their own schedule (Google every few hours).

Keep the address secret. **New address** makes a new one and stops the old one working.
