Send a Slack alert to the team when a Weezly invitee cancels
When an invitee cancels a scheduled event in Weezly, this workflow posts a message to a Slack channel with the booking details you map, so your team knows a slot has opened without checking the calendar.

What this workflow does
A cancelled booking is easy to miss. The calendar updates quietly, and the person who was going to run the meeting may not notice until the time comes. This workflow tells your team in Slack as soon as Weezly records a cancellation.
The Weezly trigger fires when an invitee cancels a scheduled event, and the cancellation's details become fields in FlowMattic. The Slack step then uses Send Channel Message to post to the channel you choose. Write the alert text and place the Weezly details in it, so the post shows who cancelled and which meeting is affected.
Only cancellations start this workflow; new bookings don't post here. The message goes to a channel, not to a single person, so pick one your hosts follow. Task History records each cancellation received and Slack's response.
Sales demos that drop out
A prospect cancels a demo booked through Weezly, and the sales channel sees it, so the rep can reach out to rebook or offer the slot to someone else.
Clinic or salon appointment gaps
Front-desk staff watching a Slack channel learn of a cancelled appointment and can call a client on the waiting list.
Consultants sharing a calendar
A small consultancy keeps a #bookings channel. Every cancellation appears there, so whoever is free can plan around the gap.

After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.
Make it yours
Changes worth making after you import it.
- Cancel a test booking in Weezly after import so FlowMattic captures the fields, then decide which ones the Slack alert should show.
- Add a Filter after the trigger if only some meetings matter, for example continue only when an event detail from a test run matches your paid consultations.
- Log each cancellation in Google Sheets with an extra step after Slack, so you can see over time which meetings get cancelled most.
Questions about this workflow
Does a new Weezly booking also post to Slack?
No. The trigger is Invitee Canceled, so only cancellations run the workflow. Weezly also has an Invitee Created trigger in FlowMattic if you want new bookings announced in a separate workflow.
Can the Weezly cancellation alert go to the host directly?
The template sends every Weezly cancellation to one Slack channel. Swap the step for Slack's Send Direct Message action if you'd rather alert one person.
Does the Slack post include the cancellation reason?
Only if Weezly sends a reason with the event and you map it. Check a test cancellation in Task History to see what is available.
Are cancellations from before the import posted?
No. Only cancellations made after you switch the workflow on reach Slack.
