/// WhatsApp automation

Bots on the same socket

Offer WhatsApp chat with bots on top of a socket-to-socket connection. Every message flows through the same real-time layer — no polling, no delay.

  • WhatsApp, fully automated

    Connect your WhatsApp Business number and let bots handle conversations around the clock.

  • Bots with real logic

    Design flows that greet, qualify, answer, and hand off to a human agent when it matters.

  • Socket-to-socket, end to end

    Messages travel over the same low-latency socket layer that powers the rest of PubSub.

PubSub holds a persistent WebSocket connection to every client, so events are pushed the moment they happen instead of being polled for. Messages typically reach connected users in under 100ms.
