FAQPage Schema
How do I add real-time pub/sub messaging to a distributed application?

You implement real-time pub/sub messaging by connecting clients to channels where they can publish and subscribe to live data. Ably provides this capability using its global edge infrastructure for low-latency message delivery across distributed regions.

What is presence in real-time messaging and how does it work?

Presence in real-time messaging tracks the online state of clients subscribed to a specific channel. Ably supports presence detection, enabling collaborative experiences like live chat by synchronizing user state across web and mobile clients instantly.

Can I use token-based authentication for real-time messaging channels?

Yes, token-based authentication is supported for securing real-time messaging channels. Ably integrates token-auth to manage access control, ensuring only authorized clients can publish, subscribe to messages, or update presence.

Does real-time messaging support message history for live chat applications?

Real-time messaging supports message history to retain data after it is published. Ably includes history capabilities alongside presence and push notifications, allowing live chat applications to recover missed messages and synchronize state.

When do I need server-side REST versus a realtime client for pub/sub messaging?

Server-side REST clients suit publishing messages and managing channel state without a persistent connection, while realtime clients maintain continuous connections for instant pub/sub messaging and presence updates across distributed clients.

What is the best way to coordinate live data and push notifications across mobile platforms?

The best way to coordinate live data and push notifications is using a real-time pub/sub messaging service with a global edge network. Ably provides low-latency delivery and push notifications to synchronize state across mobile platforms reliably.
