Introduction

What is WhatsRB Cloud?

WhatsRB Cloud turns inbound WhatsApp messages into structured, actionable data your backend can execute — without building any AI yourself.

Customer: "I need towels for room B12"
    → AI Agent classifies, extracts, routes
    → Webhook: { type: "hospitality.room_service.request", payload: { room: "B12", items: "towels" } }
    → Your backend handles it

You define agents with a system prompt and constraints. WhatsRB handles the rest: message reception, batching, spam filtering, AI routing, structured extraction, conversation memory, and signed webhook delivery.

Quickstart

Create your first agent and receive a structured webhook in 5 minutes.

How it works

Connect WhatsApp

Link your WhatsApp Business Account via OAuth or manual token. WhatsRB handles Meta’s API, tokens, and rate limits.

Create an agent

Define a system prompt, constrain the output with allowed actions and typed fields. The agent knows your domain — you control what it can return.

Receive structured webhooks

Every inbound message is processed by your agent and delivered as a signed webhook with predictable, typed actions your backend can safely parse.

Core capabilities

Capability	What it does
AI Agents	LLM-powered processors that classify intent, extract fields, and propose actions
Allowed Actions	Schema-level enum constraint — the AI can only return action types you define
Structured Fields	Typed payload schema (text, number, date, boolean) — predictable extraction
Conversation Context	Agents remember previous exchanges per phone number (configurable TTL)
Human Takeover	Pause the AI per-conversation when a human needs to respond
Inbound Pipeline	Debounce → spam filter → routing → agent run — 2 LLM calls, ~$0.0004/message
Webhooks	HMAC-signed delivery with retry for every event (runs, messages, statuses)
Templates	Create, version, and send WhatsApp-approved message templates

Who is it for?

WhatsRB is a horizontal platform — business-logic agnostic. You bring the domain, we bring the AI pipeline.

Hospitality — guest requests, room service, booking changes
Customer support — ticket creation, refund processing, escalation
Logistics & operations — dispatch, tracking, task management
Any domain — define your own agents, actions, and fields

Your backend stays in control. WhatsRB classifies and extracts — your systems execute.
