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.

Fast replies

Powered by Sarvam 105B and its conversation-tuned variant for Indic dialogue. 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

Use Cases

WhatsApp chatbot use cases by industry

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

E-commerce customer on mobile phone

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

Typically 80% of support queries resolved without a human agent.

Doctor using phone for appointments

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, with HIPAA-aware data handling throughout.

Result

Typically 40% reduction in no-shows via automated reminders.

Real estate property viewing

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 typically convert 3x faster.

Result

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

Students with mobile phones

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.

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

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

D2C brand packaging

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.

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.

support_bot.pyPython
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-105b", # or gpt-5.6-sol, kimi-k2.6, glm-5.2 ... 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)

Python example using the OpenAI SDK, pointed at CallMissed.

Full docs at docs.callmissed.com. The API handles streaming, tool use, structured output, vision, and multi-turn conversations out of the box.

FAQ

WhatsApp chatbot questions, answered

Short, honest answers, no marketing fluff.

What is a WhatsApp chatbot and how does it work?

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 105B for Indic languages and hands off to a human agent with full context when needed.

Do I need a verified WhatsApp Business account to use CallMissed?

Yes. To send chatbot messages through WhatsApp, you need a WhatsApp Business API account (not the consumer WhatsApp Business app). CallMissed partners with Meta via the Cloud API. You'll need: a verified business, a phone number dedicated to WhatsApp Business, and Meta Business Manager access. Our onboarding team helps you get verified within 24–48 hours on the Pro plan.

Can the WhatsApp chatbot handle Hindi, Tamil, and other Indian languages?

Yes, all 22 scheduled languages of India: Hindi, Tamil, Telugu, Bengali, Marathi, Kannada, Gujarati, Punjabi, Malayalam, Odia, Assamese, Urdu, Sanskrit, Kashmiri, Konkani, Sindhi, Dogri, Manipuri, Bodo, Maithili, Santali, and Nepali. CallMissed uses Sarvam AI's Indic-optimized models which handle code-switching (Hinglish, Tanglish) naturally: a customer can mix Hindi and English in one message and the bot understands both.

How much does a WhatsApp chatbot cost with CallMissed?

CallMissed offers a free tier with 50 conversations per month and 1000 API credits that never expire. Paid plans start at ₹0 on the CRM side plus pay-as-you-go AI token costs. Meta charges per delivered template message, not per conversation. In India that is ₹0.8631 for marketing and ₹0.1150 for utility or authentication templates. Replies you send inside the 24-hour customer service window are free today. On top of Meta's rate you only pay for the LLM tokens your bot actually uses.

How long does it take to build a WhatsApp chatbot?

With CallMissed, deploying a production-grade WhatsApp chatbot takes 10–15 minutes if you already have your WhatsApp Business API credentials and knowledge-base documents. Step-by-step: (1) sign up free at console.callmissed.com, (2) create a new bot and write a system prompt, (3) upload your FAQ/product docs, (4) paste your WhatsApp API credentials, (5) activate. No coding required. Developers can also use our OpenAI-compatible REST API for full programmatic control.

Can the chatbot escalate to a human agent?

Yes. You define escalation triggers in the system prompt, for example, 'escalate if the customer uses negative sentiment words', 'escalate for refund requests above ₹5000', or 'escalate if the customer explicitly asks for a human'. When triggered, the conversation routes to your team's unified inbox with the full transcript, customer profile, and sentiment analysis attached, so your agent can pick up without repeats.

Is my customer data safe?

Every conversation is end-to-end encrypted via WhatsApp's own protocol. CallMissed runs DPDP Act-aligned infrastructure with India data residency (Azure Central India region). We never use your customer data to train shared models, and tenant isolation means another business on CallMissed cannot access your bot, knowledge base, or conversations. Enterprise plans get dedicated single-tenant deployment and BAA for healthcare.

Can I integrate the WhatsApp chatbot with Shopify, Salesforce, or my existing CRM?

Yes. CallMissed integrates with Shopify, WooCommerce, Salesforce, HubSpot, Zoho, Razorpay, Calendly, Google Sheets, and any system via webhooks or REST API. Your chatbot can look up orders in Shopify, create HubSpot contacts, trigger Razorpay payment links, or update Salesforce opportunities, all inside a single WhatsApp conversation.

Does the chatbot work on the WhatsApp Business app or only WhatsApp Business API?

The CallMissed chatbot requires the WhatsApp Business API (Cloud API or On-Premise API), not the free WhatsApp Business app. Meta reserves automated messaging and bots for the API. The WhatsApp Business app is designed for single-device manual use by small businesses. If you're currently on the app, CallMissed's onboarding team helps you migrate to the API in 24–48 hours.

What LLM powers the WhatsApp chatbot?

You can pick from a growing catalogue, with models added on demand: Sarvam 105B (default; best for Indian languages, fast, cost-efficient), gpt-4o and gpt-5-mini, GPT-5.6, Kimi K2.6, GLM 5.2, Grok 4.3, DeepSeek-V4, and more. Enterprise customers can route different conversation types to different models, e.g., Sarvam for routine queries, GPT-5.6 for complex escalations.
