Connect Google Calendar to Slack — No Code Required
Automate the handoff between Google Calendar and Slack using plain English. Describe what you want to happen and Vendarwon Flow builds and runs the workflow automatically — forever, in real time, without developer help.
Why teams connect Google Calendar to Slack
Upcoming meetings, reminders, and schedule changes in Google Calendar affect everyone — but most people don't check their calendar until it's too late. Connecting to Slack posts reminders and updates automatically in the chat tool the whole team already uses.
CRM deals, new orders, and code events post to Slack the instant they happen — no one needs to relay them
High-priority alerts reach the right channel or person before anyone even knows to check
Daily digests and summaries post automatically — no manual compilation, no formatting time
What you can automate between Google Calendar and Slack
When a new event arrives in Google Calendar, automatically post a message to a channel in Slack — no manual work, no delay
Route specific Google Calendar events from key sources and send a direct message in Slack the moment they arrive
Build a scheduled digest: collect Google Calendar activity over time and post a formatted alert with details in Slack on a daily or weekly schedule
When a high-priority event is detected in Google Calendar, notify a specific person instantly in Slack with all the relevant context included
Filter Google Calendar events by keyword, sender, or category — then post a message to a channel in Slack only for the ones that matter
Create a two-way feedback loop: every qualifying event in Google Calendar triggers a record in Slack that your team can track and act on
What you stop doing manually
Google Calendar is valuable — but without automation, it creates repetitive manual work. Here is what teams eliminate the moment they connect Google Calendar to Slack:
Creating calendar events manually after every booked meeting, new deal, or deadline added elsewhere
Sending reminder emails or Slack messages for upcoming events by hand each time
Copying event details from emails or forms into Google Calendar one entry at a time

About Google Calendar and Slack
Google Calendar
Calendar
Google Calendar coordinates schedules for over 500 million users and is the central tool for managing meetings, deadlines, and events. The friction is creating events, sending reminders, and acting on calendar data — all of which most teams still do manually one entry at a time.
Available triggers
- new calendar event created
- event starting soon
- event cancelled or updated
Available actions
- create a calendar event
- send a meeting invite
- schedule a reminder
- block time on a calendar
Slack
Team Messaging
Slack is the team communication hub used by over 750,000 companies worldwide. While it excels at conversation, the painful reality is that most alerts, updates, and status changes from other tools still get posted to Slack manually — by a person copy-pasting from another tab.
Available triggers
- new message posted in a channel
- keyword or mention detected
Available actions
- post a message to a channel
- send a direct message
- post a formatted alert with details
- notify a specific person instantly
Frequently asked questions
Does Google Calendar have a native Slack integration?
Google Calendar and Slack do not have a built-in direct integration that covers most real automation scenarios. Vendarwon Flow acts as the bridge — you describe what you want in plain English and it handles the API connections between both tools securely. No Zapier account, no developer, no webhook configuration needed.
What Google Calendar events can trigger the automation?
With Vendarwon Flow you can trigger automation from any of these Google Calendar events: New calendar event created; event starting soon; event cancelled or updated. You can also combine triggers — for example, only fire the automation when a event matches a specific keyword or comes from a particular source.
What can the automation do inside Slack?
Once triggered, the workflow can perform any of these actions in Slack: Post a message to a channel; send a direct message; post a formatted alert with details; notify a specific person instantly. You can chain multiple actions together — for example, post a message to a channel and then send a direct message.
How quickly does the automation run after something happens in Google Calendar?
In real time — typically within a few seconds of the triggering event. Vendarwon Flow runs continuously in the cloud, so there is no polling delay. The moment a new event meets your conditions in Google Calendar, the workflow fires and the action in Slack happens instantly, whether it is 2 PM or 2 AM.
Which Slack channel or person receives the automated message?
You choose. When you describe your automation, you specify the exact channel name or person — for example "post to #sales-alerts" or "send a direct message to @john." You can also set up routing logic: send to different channels based on the content or priority of the triggering event.
