Synthro and Google Calendar are better together.
Push leave, 1-on-1s, review deadlines and interviews straight into Google Calendar — and keep team availability accurate without anyone lifting a finger.
Overview
One source of truth for time — in HR and on the calendar
Your team already lives in Google Calendar. Synthro meets them there. The moment leave is approved, a review is scheduled, or a 1-on-1 is booked, it appears on the right calendars — automatically, in both directions.
No exported spreadsheets, no manual invites, no “I didn’t know you were off”. HR stays the single source of truth, and everyone sees the same accurate availability.
What you can do
- Approved leave and time-off automatically blocks an employee's Google Calendar.
- Recurring 1-on-1s and check-ins sync as calendar events — complete with agenda and notes link.
- Performance review cycles and deadlines land in managers' and employees' calendars.
- Interview slots and onboarding tasks become scheduled events — no copy-paste required.
- Team availability stays accurate so nobody books over someone on leave.

How it works
Connect your Google account
An admin authorises Google Calendar in Synthro settings using secure OAuth. No passwords are stored — access can be revoked anytime.
Choose what syncs
Pick the event types to push — leave, check-ins, reviews, interviews — and whether they sync company-wide or per team.
Work as normal
Synthro keeps both calendars in step in the background. Approve leave in Synthro and it appears in Google Calendar within seconds.
Why teams turn it on
Benefits across the whole company
No double entry
HR records and personal calendars stay in sync automatically. Approve once in Synthro — it shows up everywhere.
Real team availability
Managers see who is on leave before scheduling. Fewer clashes, fewer "sorry, I'm off that day" emails.
Reviews that actually happen
Check-in and review deadlines sit in the calendar, not in someone's memory — so performance cycles stay on track.
POPIA-aware by design
Only the event detail you choose is shared. OAuth access is scoped, auditable, and revocable at any time.
FAQ
Common questions
Is the Google Calendar sync two-way?
Synthro pushes HR events (leave, check-ins, reviews, interviews) into Google Calendar, and reads free/busy availability back so scheduling stays accurate. You control exactly which event types sync.
Do I need Google Workspace, or does a personal Gmail work?
Both work. The integration uses standard Google Calendar OAuth, so it connects with Google Workspace accounts and personal Google accounts alike.
Is it secure and POPIA compliant?
Yes. Synthro uses scoped OAuth — we never see your Google password, only the calendar permissions you grant. Access is logged and can be revoked instantly from Synthro or your Google account.
How much does the integration cost?
The Google Calendar integration is included on the Premium plan at no extra charge. Get in touch and we'll switch it on for your trial.
