  • Outlook calendar integration
  • Leave events on team and personal calendars
  • Department and manager mapping

Leave visible where your team looks.

Approved leave appears on the calendars your team already checks — Google Calendar, Outlook, or any iCal-compatible app. No manual entry required.

📅

Google Calendar

Calendar Sync

Keep leave visible in Google Calendar.

When leave is approved, it appears as a calendar event on the employee's Google Calendar. Team members can subscribe to a shared leave calendar for full visibility. Public holidays are included automatically.

  • Approved leave events on personal calendars
  • Public holidays by region
  • Team-wide leave visibility
  • Automatic updates on changes
See the Offly Calendar
📧

Outlook Calendar

Calendar Sync

Keep Outlook calendars up to date automatically.

Leave events sync directly to Outlook. When an absence is approved, it appears on the employee's Outlook calendar. Cancellations remove the event. The sync is continuous and automatic — zero manual maintenance.

  • Leave synchronisation to Outlook
  • Team visibility via shared calendars
  • Automatic updates on approval/cancellation
  • Works with Microsoft 365 and Exchange
REST API

Build your own workflows.

The Offly API gives you programmatic access to leave data, user management, and organisation configuration. Build custom reports, sync with internal tools, or create bespoke workflows that match exactly how your company operates.

  • Full REST API with JSON responses
  • Secure API key authentication
  • Leave data access — requests, balances, history
  • User and team management endpoints
  • Organisation configuration

Webhooks

React to leave events in real time.

Webhooks notify your systems the moment something happens. When leave is created, approved, declined, or cancelled, Offly sends a POST request to your configured URL with the full event payload. Build automations that respond instantly to leave changes.

  • leave.created — new request submitted
  • leave.approved — manager approved
  • leave.declined — request declined
  • leave.cancelled — request cancelled
  • Configurable retry and failure handling

Real workflows. Fully automated.

From onboarding a new employee to approving leave in Slack to syncing calendars — integrations eliminate manual steps at every stage.

Why integrations matter for leave management

Leave management touches identity, calendars, communication, and payroll. Without integrations, every connection is manual.

Reduce Manual Work

Stop copying data between systems. Leave data flows automatically — from request to calendar to notification.

Eliminate Duplicate Data

One source of truth. User data comes from your identity provider. Leave data flows to calendars and Slack. No manual sync.

Improve Adoption

When leave management lives inside tools people already use (Slack, Google Calendar), adoption is effortless.

Increase Visibility

Leave appears where teams already look — on their calendars, in their Slack channels, and on shared dashboards.

Automate Workflows

From provisioning users to approving leave to syncing calendars — every step that can be automated, is automated.

Built with security in mind.

Every integration follows security best practices — OAuth for identity, scoped API keys, audit logs, and least-privilege access.

Role-Based Permissions

Only admins can manage integrations. Team members see only what they need.

OAuth Authentication

Google and Microsoft use industry-standard OAuth 2.0. No passwords stored.

Audit Logs

Every integration action is logged — connections, disconnections, data syncs.

Secure API Access

API keys are scoped, rotatable, and never exposed in client code.

Least Privilege Design

Integrations request only the permissions they need. Nothing more.

More than a standalone leave tracker.

Most leave tools exist in isolation. Offly connects to the systems your team already uses — reducing manual work and increasing adoption.
