Littlebox Support AI — WhatsApp Pitch Demo

Founder pitch prototype only. Not affiliated with Littlebox India / Good Tribe Pvt Ltd.
Uses mock orders + policies sourced from Littlebox’s public FAQ, shipping, return, and “You Ask We Answer” blogs.
No real customer data. No connection to Littlebox’s Shopify or WhatsApp Business numbers.

Built for a cold founder-to-founder pitch: show how a conversational WhatsApp agent handles the same messages that rigid button-flow bots bounce on.

Stack

Layer	Choice
Channel	Kapso WhatsApp API (sandbox number only)
Runtime	Cloudflare Worker
LLM	OpenRouter free model (nvidia/nemotron-3-super-120b-a12b:free, tool calling + fallback)
Data	Static mock orders in src/data/orders.json

Why this wins the demo

Littlebox’s own support blog describes WhatsApp as an automated routing layer that collects order number + category before a human replies in 24–48h. This agent:

1. Accepts natural language (no forced COD/Prepaid button tree)
2. Looks up mock order context and answers with item, dates, city
3. Stays policy-accurate (store credit on returns, 7–14 day made-to-order, 24h/48h windows)
4. Sounds like a human on WhatsApp — short, direct, not corporate

Mock orders (for testing)

Order	Scenario
LB10234	Processing overdue (>14 days) — “3 weeks late” script
LB10235	Processing within window
LB10236	Dispatched — cancel blocked
LB10237	Delivered recently — not-received window
LB10238	Delivered long ago — past 24h/48h
LB10239	Damage / wrong item path

Security (read this)

• Never commit .dev.vars, .env, or real API keys.
• Secrets live in Cloudflare (wrangler secret put) and local .dev.vars only.
• This demo must use the Kapso sandbox phone number — not a production Miithii number.
• If an OpenRouter key was ever pasted into chat, rotate it after the pitch.

Setup

cd littlebox-support-demo
npm install
cp .dev.vars.example .dev.vars
# fill OPENROUTER_API_KEY, KAPSO_API_KEY, KAPSO_PHONE_NUMBER_ID, KAPSO_WEBHOOK_SECRET

Local

npm run dev
# health
curl http://127.0.0.1:8787/health
# simulate a customer (no WhatsApp needed)
curl -X POST http://127.0.0.1:8787/demo/simulate \
  -H "content-type: application/json" \
  -d "{\"message\":\"hi\",\"phone\":\"919876543210\"}"

Deploy (Cloudflare)

npx wrangler login   # once
npx wrangler secret put OPENROUTER_API_KEY
npx wrangler secret put KAPSO_API_KEY
npx wrangler secret put KAPSO_PHONE_NUMBER_ID
npx wrangler secret put KAPSO_WEBHOOK_SECRET
npm run deploy

Live demo (Prompt Mafia account)

Health	https://littlebox-support-demo.promptmafiainc.workers.dev/health
Simulate (no WhatsApp)	POST /demo/simulate with { "message": "...", "phone": "91..." }
Kapso webhook	POST /webhooks/kapso (wired to sandbox number)

curl -s -X POST https://littlebox-support-demo.promptmafiainc.workers.dev/demo/simulate \
  -H "content-type: application/json" \
  -d '{"message":"I ordered a dress three weeks ago. LB10234","phone":"919876543210"}'

In Kapso: webhook on the sandbox number → event whatsapp.message.received → same secret as KAPSO_WEBHOOK_SECRET.

Optional KV session memory:

npx wrangler kv namespace create SESSIONS
# paste id into wrangler.toml [[kv_namespaces]]
