Absenca integrations: leave that fits your stack
Book and approve time off in Slack, push approved leave to Google Calendar and Outlook, and sign in with Google, Microsoft or Slack. Bots for Microsoft Teams and Google Chat are on the way.
Free for up to 10 people · 11 to 50 people: $37.50 a month on Pro
Absenca integrates with Slack (a bot for leave requests, approvals and who's off), Google Calendar and Outlook (approved leave on each person's own calendar), Google, Microsoft and Slack sign-in, and any calendar app through live .ics feeds, and it imports your roster from a CSV. Bots for Microsoft Teams and Google Chat are built and coming soon, but neither can be installed yet. A leave tracker only gets used if it meets people where they already work, so Absenca connects to the chat tool, calendars and accounts your team uses every day — and keeps the single source of truth for balances, approvals and policies in one place.
Which plan includes what: personal Google and Outlook calendar sync is on every plan, the free Starter plan included. CSV roster import works on every plan. The Slack bot and shared org calendars are on Pro and the Custom Pack, not on the free Starter plan. Absenca is free for up to 10 people. Pro is $37.50 a month for up to 50 people, or $33.75 a month billed annually ($405 a year).
What you get
Slack bot
Request leave with /absenca leave, approve from the message, check balances and who's out, and post a daily or weekly who's-off summary to a channel. Available on Pro and the Custom Pack, not on the free Starter plan.
Google Calendar sync
Approved leave lands on each person's own Google Calendar, all day or as a half-day block, with an optional out-of-office entry. Available on every plan, the free Starter plan included.
Outlook calendar sync
Approved leave lands on each person's Outlook calendar, shown as out of office, and in the Teams calendar, which displays the same calendar. Available on every plan, the free Starter plan included.
Shared calendars and .ics feeds
Give a team or office one calendar of who's away, or subscribe any calendar app to a live .ics leave feed. Shared org calendars are available on Pro and the Custom Pack, not on the free Starter plan.
Google, Microsoft and Slack sign-in
Staff sign in with the Google Workspace, Microsoft 365 or Slack account they already have — no new password to set, forget or reset.
CSV bulk import
Onboard your whole roster — names, emails, departments, offices, start dates — from a spreadsheet in one upload, instead of adding people one by one. Works on every plan.
Microsoft Teams bot: coming soon
Built, but not available to install yet. Until it is, leave synced to Outlook already shows up in the Teams calendar.
Google Chat bot: coming soon
Built, but not available to install yet. Until it is, people who turn on out-of-office get a Google Calendar out-of-office entry that Google Chat can show to colleagues who message them.
Chat-first: Slack
For most teams the chat integration is the one that drives adoption. With the Slack bot, an employee types /absenca leave, the request lands with their manager as a Slack message with Approve and Reject buttons, and a single click decides it. The employee gets a direct message with the answer, and the shared calendar updates instantly.
You can post a summary of who's away to a channel, daily or every Monday, so nobody has to ask "is anyone out today?" before planning a meeting. And because every Slack action is recorded against the same balances and audit log as the web app, the convenience never costs you accuracy.
Every command is listed on the dedicated Slack integration page.
Calendars: Google, Outlook and shared feeds
Approved leave should be visible where people already check their week. Absenca syncs to personal Google Calendar and Outlook / Microsoft 365 calendars, so an approved day off shows up alongside meetings — no separate place to remember.
Beyond personal sync, shared org calendars and live .ics feeds let a whole team, department or office subscribe to everyone's absences in one calendar. It's a one-way, read-only view that stays current automatically, which is exactly what you want for planning coverage. Shared org calendars are on Pro and the Custom Pack, not on the free Starter plan.
Onboarding: CSV import and single sign-on
Getting set up shouldn't mean retyping your staff list. A CSV bulk import brings in your whole roster — with departments, offices and start dates — in a single upload, so new accounts and pro-rated balances are ready in minutes.
People then sign in with the Google Workspace, Microsoft 365 or Slack account they already use, so there's no separate password to provision or reset, and email and password sign-in stays available for everyone else.
Coming soon: Microsoft Teams and Google Chat
Absenca's Microsoft Teams and Google Chat bots are built, with the same everyday commands as the Slack bot, but neither can be installed yet. Both platforms already show Absenca leave today: Teams through the Outlook calendar it displays, and Google Chat through the Google Calendar out-of-office entries Absenca adds for people who turn out-of-office on.
See what works today and what each bot will do on the Microsoft Teams and Google Chat pages.
