FAQs
An event bus captures and routes events between systems, enabling communication without direct dependencies. This decouples workflows, allowing applications to scale independently and remain resilient to failures.
A publisher is the source of an event, generating and sending event data to the event bus. It can be a Zoho app, Catalyst component, or custom application that triggers downstream actions.
Catalyst Signals enables real-time data flow across systems using event-driven architecture. By routing and synchronizing events across applications, it ensures consistent, unified data without silos.
A system design where data and actions move in real time the instant an event happens (e.g., "invoice paid," "deal won," "stock updated") - Signals reacts to events as they occur instead of polling for changes.
Real-time automation, smart backend workflows, operational-system orchestration, decoupled and scalable architectures, data pipelines, integrations with external or custom systems, and feedback loops.
Events from three kinds of source:
- Zoho services (CRM, Books, Billing, Bigin, Inventory, Commerce, Survey, etc.)
- Catalyst services (currently CloudScale components)
- Custom publishers via REST API - any custom event can be pushed in
Create a publisher (a Zoho app or custom REST source), define a rule (filters, transformations, targets), choose a delivery mode (queue or batch), set up a target (Function, Circuit, or Webhook), then start sending events and monitor delivery.
Zoho Flow is a no-code, visual automation tool for structured, sequential app-to-app workflows built on pre-built connectors. Catalyst Signals is a developer-focused, real-time event routing system built for high-volume, dynamic processing with filtering, transformation, and queue or batch delivery.
CRM Signals is a built-in CRM feature that alerts sales reps to customer interactions (email opens, chats, form fills) inside the CRM. It will soon run on top of Catalyst Signals for added reliability and scale.
Publishers send events into a rule engine, which routes them to targets either one at a time in the order received (queue mode) or grouped by size, count or schedule (batch mode).
Configurable retries and TTL settings apply, and failed events can be monitored and reprocessed through delivery logs.
Yes. Because events are pushed rather than polled, reactions are typically under one second, depending on processing and transformation latency.
Yes, through the Custom Publisher option using the REST API, which lets you bring non-Zoho systems into event-driven workflows.
