Fluent Booking takes the appointments on your WordPress site, and your hosts read Slack all day. FlowMattic sends each host their new bookings by direct message, posts completed meetings and cancellations to channels and flags reschedules. Agencies with several sites can follow remote bookings in one workspace. For consultants, sales teams and clinics.

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 templateFind User by Email finds the host in Slack and they get the guest's name, time and answers in a direct message, so nobody checks the calendar for new meetings.

Reschedules are easy to miss in an email. The host gets a direct message with the old and new times, so they can move their preparation.

Each client site sends its confirmed bookings to this site. A Router reads which site the booking came from and posts it to that client's channel.

When Fluent Booking sends its reminder to the guest, the host gets a Slack message too, so both sides are reminded before the meeting.

Bookings agreed outside the calendar, such as by phone, can be posted to a Webhook. Create Booking adds it to the event and the channel hears about it.

When done, each confirmed Fluent Booking reaches its host as a Slack direct message.
Under Connects, add a Slack connection for your workspace. Fluent Booking runs on your site and needs no connection.
Create a workflow with the Fluent Booking Booking Confirmed trigger and make a test booking so FlowMattic captures the booking fields.
Add Slack Find User by Email and map the host's email from the booking.
Add Send Direct Message to the user found, include the guest's name, time and answers, test it and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Fluent Booking and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Booking details go from Fluent Booking to Slack through your own WordPress site, with no third automation account holding guest data.
Runs are unlimited, so a busy calendar or an agency following many client sites needs no bigger FlowMattic plan.
Direct messages go to the host of each booking, and channels hold only the events a team cares about.
Create a workflow with a Fluent Booking trigger such as Booking Confirmed, then add Slack Send Channel Message or, for the host only, Find User by Email and Send Direct Message.
Yes. Use the Remote triggers, such as Booking Confirmed (Remote), on the site that runs FlowMattic, and point each other site's Fluent Booking webhook at it.
Yes. Booking Rejected fires when a host rejects a pending booking. Post it to a channel so whoever handles enquiries can offer the guest another time.
Yes. Add a Filter after the trigger that checks the event or calendar name, so only, for example, sales calls reach the sales channel.
