OpenTag + Google Calendar

Put Google Calendar to work from Slack

Ask a question or describe the work you need in plain English. OpenTag uses the tools exposed by your Google Calendar connection, then brings the result back to the channel or DM where the work started.

Use your calendar to prepare for the next conversation

OpenTag can read events and availability from the Google Calendar account you connect. Pair calendar details with accessible Granola notes for a private meeting brief, or ask for available times before deciding what to book.

Prepare for external meetings

Example request — replace the bracketed details with your own.

For external meetings on [calendar], send a private Slack brief 45 minutes before the start. Include attendees, relevant Granola history, open commitments and source links. Use [timezone] and exclude personal events and focus blocks.

Find a time

Example request — replace the bracketed details with your own.

Find three free half-hour slots next week for [attendees] on [calendar], using [timezone]. Do not book a slot or invite anyone yet.

What to check before you connect

  • Review Google Calendar sharing separately from Gmail and Drive. Name the calendar, timezone and attendees in the request.
  • Creating or changing events requires the appropriate access. A briefing or availability check does not need to change the calendar.
  • Calendar writes that can invite attendees are held in scheduled routines. Interactive calendar edits do not all require a separate approval card.
Setup and permissions guideConnection sharing and access

Connect once, then ask from Slack

The connection dialog is the source of truth for the accounts, permissions, and actions available to your workspace.

  1. 1

    Choose Google Calendar

    Open Integrations in OpenTag, select Google Calendar, and authorise the account you want to use.

  2. 2

    Review access

    Check the sharing and read or write choices shown for that account before completing the connection.

  3. 3

    Start the work

    Mention OpenTag in an invited Slack channel or DM and say what you need from the connected account.

Your account stays within the access you choose

Integrations belong to the person who connected them. OpenTag uses the selected account only when a request needs it, and a connection set to read only stays read only.
