How it works

Every step, explained

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

Webhook → Slack

2 steps

TRIGGER

Webhook · Capture Webhook Response

The workflow starts when data is sent to its unique webhook URL. Point any app, form or service at the URL and its payload flows into every step below.

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.
