Listener Vertex
Watch a vertex. React to change. Start a workflow.
Listener Vertex turns any Node Vertex URL into an event source. Monitor form submissions, payment updates, file uploads, device signals, agent outputs, or simple value changes, then trigger email, Teams, Jira, downstream vertices, or complete polygon workflows.
Reactive vertices
A Listener Vertex makes a URL reactive.
A vertex can hold data. A listener vertex can watch it. A polygon can turn the reaction into a workflow.
Forms become workflows
A Form Vertex writes submissions into info-requests. A Listener Vertex watches it and sends email, creates tickets, or writes to another vertex.
Payments become activation
A payment-confirmed vertex can trigger activation, fulfillment, license issuance, onboarding, and customer notification.
Devices and agents become composable
Agents, IoT devices, logs, files, and status vertices can all become triggers without custom polling jobs or brittle glue code.
From form submission to action
info/contact -> [form] -> info-requests -> [listener] -> email notification
A submitted form appends structured JSON to a destination vertex. A listener watches the destination vertex for new entries, sends an email to the business owner, and records delivery status in listener action history.
Stop wiring brittle glue code. Listen to the vertex.
Instead of asking every system to call every other system, write to a vertex once. Listeners react based on append events, value changes, or conditions and can fan out to email, integrations, downstream vertices, polygons, and constellations.
Every workflow starts with a vertex.
