Important events often get added to your calendar—team meetings, client calls, or project deadlines. But unless someone remembers to post the details in Slack, parts of your team can be left out of the loop. Manual updates are easy to miss and slow down communication. With Workload, you can remove the hassle by automating the process to share Google Calendar events in Slack automatically.
As soon as a new event is created, the details flow directly into a Slack channel. Titles, times, and locations appear where your team already collaborates, so everyone stays on the same page without relying on reminders or extra messages.
This automation saves time, reduces mistakes, and keeps your team aligned. Workload makes it effortless to stay organized and ensure your team never misses what’s on the calendar.

📅 Google Calendar
Create and track events that will automatically trigger Slack updates.

⚙️ How to Share Google Calendar Events to Slack Automatically
Apps expect data in different formats—like dates, names, or labels. Workload’s built-in AI Wizard lets you clean or adjust data between steps. If your trigger already sends clean data, you can skip formatting altogether.
Step 1: Create a New Automation (Workload)
Open the Workload dashboard and select Create Workflow.
Name your automation (ex: Google Calendar Events to Slack).
Step 2: Set Up the Trigger (Google Calendar)
Open the Trigger box and choose the Google Calendar app.
Set the trigger event to New Event, then continue.
Click Sign in to connect your Google Calendar account if you haven’t done so already. For help, follow our step-by-step guide on how to connect Google Calendar to Workload. Once connected, click Continue.
Pick the calendar you want Workload to watch for new events, then click Continue.
Run a test to fetch sample event data by clicking Test Trigger.
Confirm the test worked, then hit Continue.
Step 3: Add Send Channel Message Action (Slack)
Click into the action step and choose Slack.
Set the action event to Send Channel Message, then Continue.
Click Sign in to connect your Slack account if you haven’t done so already. For help, follow our step-by-step guide on how to connect Google Calendar to Workload. Once connected, click Continue.
Next, map your fields you want to include in the channel message. Once you have finished mapping the fields, click Continue. Note: We used the following fields:
- Channel → Slack channel (pick from dropdown)
- Message Text → Event Summary, Description, Location, Start Time, End Time (from Step 2 – Google Calendar)
- Bot Name → Event Summary (from Step 2 – Google Calendar)
- Thread / Icon (optional) → Leave blank if not needed
Send a test action to post a sample message.
Check your Slack channel to verify the message arrived correctly. Once verified, go back to the Workload Editor and click Continue.
Step 4: Test and Activate the Automation (Workload)
Look over each step to confirm every node is green and then switch the automation toggle to On.
* Your automation is now active—every new Google Calendar event will automatically post to your chosen Slack channel.
