How it works

Launch a production WhatsApp chatbot in 4 steps

No code required. If you can write a 3-paragraph brief for a new hire, you can build a CallMissed chatbot.

Create a bot

Upload knowledge

Drop in PDFs, docs, FAQs, or product catalogs. The AI grounds every answer in your content — no hallucinations.

Connect WhatsApp

Paste your Meta WhatsApp Business API credentials. We handle the webhook. Takes under 2 minutes.

Go live

Flip the switch. Your chatbot starts answering customer messages in seconds — in their language.

Features

Everything your WhatsApp chatbot needs

Built for Indian businesses. Priced so a 5-person team can afford it, scaled so a 5000-person team won't outgrow it.

22 Indian language support

Hindi, Tamil, Telugu, Bengali, Marathi, Kannada, Gujarati, Punjabi, Malayalam, and 13 more. Customers write in their language — the bot replies in the same language, including Hinglish.

Knowledge base grounding

Upload PDFs, DOCX, TXT up to 20MB. Your chatbot answers strictly from your content — product catalogs, return policies, FAQs, SOPs.

Smart human escalation

Define escalation rules. Angry customers, complex technical issues, or high-value leads route to your team with full context — no repeats.

Sub-2-second replies

Powered by Sarvam 30B (real-time) and 105B (complex reasoning). Streaming tokens means the customer sees a reply as it's being written.

Rich media + templates

Send and receive images, PDFs, audio, location pins. Use Meta-approved message templates for marketing, OTP, order updates, shipping notifications.

Analytics that matter

Track conversation volume, resolution rate, language breakdown, sentiment, CSAT, and cost per conversation from a single dashboard.

Use Cases

WhatsApp chatbot use cases by industry

From D2C to BFSI, here's how Indian businesses deploy CallMissed chatbots.

E-commerce

Order support on autopilot

Customers ping your brand on WhatsApp asking about order status, returns, sizing, and delivery ETAs. Your AI chatbot pulls order data from Shopify/WooCommerce and answers instantly — in Hindi, Tamil, or whichever language they used.

Result

80% of support queries resolved without a human agent.

Healthcare

Appointment booking 24/7

Patients book, reschedule, and cancel appointments on WhatsApp. The chatbot collects pre-visit intake forms, sends reminders, and answers common medical FAQs from your approved content — HIPAA-aware data handling throughout.

Result

40% reduction in no-shows via automated reminders.

Real estate

Lead qualification before human handoff

When a buyer messages about a property, the chatbot qualifies them — budget, location, timeline, property type, loan status — and only then routes to a sales agent with full context. Qualified leads convert 3x faster.

Result

3x sales-agent productivity, 5x MQL-to-SQL conversion.

EdTech

Admissions + student support

Answer course catalog questions, fee structures, deadlines, and enrollment steps 24/7. Your chatbot pushes study materials on request, sends fee-due reminders, and escalates genuine counseling requests to advisors.

Result

60% of admissions queries resolved before office hours.

Fintech & BFSI

Balance + transactions on WhatsApp

Customers check balance, review transactions, track loan application status, and get product recommendations — all via WhatsApp. End-to-end encryption plus your own tenant data means nothing leaks.

Result

50% lower call-center load during month-end spikes.

D2C brands

Pre-sales + upsell automation

Handle size recommendations, product comparisons, bundle suggestions, and checkout recovery. The chatbot nudges customers who abandoned cart, shares personalized offers, and routes hot leads to your sales team.

Result

25% uplift in recovered-cart revenue.

Developer API

Or build with code — the OpenAI-compatible way

Prefer code? The CallMissed WhatsApp chatbot is also available as a REST API. Drop it into any language — it's OpenAI-compatible, so if you've ever called openai.chat.completions.create(), you already know how to use it.

python

from openai import OpenAI

client = OpenAI(
    base_url="https://api.callmissed.com/v1",
    api_key="cm_your_key_here",
)

response = client.chat.completions.create(
    model="sarvam-m",              # or gpt-4o, claude-4-sonnet, gemini-2.5-pro ...
    messages=[
        {"role": "system", "content": "You are a customer support agent for Acme Electronics. Answer only from the provided knowledge base."},
        {"role": "user", "content": "मेरा order कब आएगा? Order ID 45231"},
    ],
    stream=True,
)

for chunk in response:
    print(chunk.choices[0].delta.content, end="", flush=True)

FAQ

WhatsApp chatbot questions, answered

Short, honest answers — no marketing fluff.

A WhatsApp chatbot is an AI-powered automated assistant that chats with customers through the WhatsApp Business API. When a customer messages your business number, the chatbot reads the message, understands the intent using a large language model (LLM), looks up answers from your uploaded knowledge base, and replies in the customer's language — all in under 2 seconds. CallMissed's WhatsApp chatbot uses Sarvam 30B/105B for Indic languages and can seamlessly hand off to a human agent when needed.
