Prerequisites

Before using Signals, activate it once per project in the console:

Console → your project → Signals (left sidebar) → click "Start Exploring"

Skipping this step prevents access to Publishers, Webhooks, Rules, and Logs. This is a one-time activation per project.

How It Works

Console-Only Service — HARD STOP if user expects SDK/API. Catalyst Signals is configured entirely through the Catalyst Console — there is NO SDK, REST API, or programmatic interface for creating publishers, rules, or webhooks. All setup is done via the console UI.
- Publishers, events, webhooks, and rules are created in Console → Signals
- Functions and Circuits are created separately in Console → Serverless, then selected as targets in Signals rules
- The only code-level interaction is receiving events in target functions/circuits
