Let your team hear about bookings in Slack. New bookings post to a channel, hosts get a direct message when their session moves, cancellations tell the front desk a slot is free, and each morning starts with the day's agenda. FlowMattic Bookings and its workflows run on your own WordPress site, with your own calendars.

1. TriggerNew Booking2. ActionSend Channel MessageWhen Bookings fires New Booking, FlowMattic runs Send Channel Message in Slack with the data from that event.
You build this in the FlowMattic workflow builder on your own site. See the setup steps
Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateEveryone who covers the calendar sees who booked, which calendar and when as soon as the booking is made, so nobody has to refresh the bookings screen.
New BookingSend Channel Message
View the template A cancelled booking posts the freed time to the reception channel, so staff can offer it to someone on the waiting list or move another client forward.
Booking CancelledSend Channel Message
Hosts are the ones who need to know. The workflow matches the host's email to their Slack account and sends the old and new time in a direct message.
Booking RescheduledFind User by EmailSend Direct Message
When a booking is marked no-show, the attendee gets a friendly email with a link to book again, and a private channel records the miss for whoever handles fees.
Booking Marked No-ShowSend Email to BookingSend Private Channel Message
Sales reps send single-use booking links to prospects. When the link is booked, the rep gets a direct message, which is often the first sign the prospect is serious.
Single-Use Calendar Booking ReceivedFind User by EmailSend Direct Message
At the start of the day Find Bookings lists today's sessions and one Slack message gives the team the agenda: times, names and calendars.

Once a booking is marked completed, Slack sets a reminder for the host for the next morning to send notes, an invoice or a review request.

At the end, every booking on the calendar you pick is announced in your Slack channel.
Under Connects, add Slack with an account that is a member of the channel. Bookings is part of FlowMattic and needs no connection.
Create a workflow with Bookings New Booking, pick the calendar and make a test booking so FlowMattic captures its fields.
Add Slack Send Channel Message, choose the channel and build the text from the attendee name, calendar and start time.
Test the step, check the post in Slack and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Bookings and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
New, moved, cancelled and missed bookings reach the people who act on them, in the place they already read.
Calendars, bookings and workflows all run on your WordPress site, so client details go only to the Slack channels you choose.
Runs are unlimited on every plan, so a clinic or studio with hundreds of bookings a week pays nothing per message.
Create a workflow with the Bookings New Booking trigger and add Slack Send Channel Message. Pick the channel, add the attendee, calendar and time to the text, test once and switch it on.
Yes. Use Find User by Email with the host's email and Send Direct Message, so each person hears about their own sessions. A Router can also send each calendar to its own channel.
Not with these workflows, which only send messages to Slack. To cancel, use the bookings screen in wp-admin, or a workflow that runs Cancel Booking, for example from a form or a Webhook.
Yes. Set the calendar and date range in Find Bookings, and build one scheduled workflow per team if each team has its own calendar and channel.
Yes. Add Send Email to Booking before or after the Slack step. The no-show example does this, sending a rebook email and a Slack message from the same trigger.
