How it works

Every step, explained

Import the template and this whole chain runs on autopilot — here's exactly what happens on each run.

WordPress → Image Builder → Slack
3 steps
WordPress
TRIGGER
WordPress · New Post
The workflow starts automatically when a new post is published in WordPress. FlowMattic captures that data for the steps below.
Image Builder
ACTION
Image Builder · Generate Image from Template
Image Builder — pick a saved Image template, supply dynamic data (as JSON or per-token inputs), render the HTML through Cloudflare Browser Rendering, and save the PNG to the Media Library. Data is mapped from earlier steps; connect your Image Builder account on import.
Slack
ACTION
Slack · Send Channel Message
Slack — post or Schedule a new message to a specific #channel. Data is mapped from earlier steps; connect your Slack account on import.
Why this workflow

Built to own, not to rent

No-code setup

Import the JSON, connect your accounts, and go live in minutes. Every step is pre-mapped — you only add your own credentials.

Runs on your server

Self-hosted on your WordPress install. No per-task fees, no data leaving your infrastructure, no monthly SaaS bill.

Fully customizable

Open it in the visual builder and reshape it — add branches, swap apps, insert filters. A starting point, not a cage.
