What is the WhatsApp Business API?
The WhatsApp Business API, now called the WhatsApp Business Platform, is Meta's official way for businesses to message customers at scale. Unlike the free WhatsApp Business app, it works with software: many agents on one number, automated chatbots, bulk broadcasts to opted-in customers, and integrations with your website, CRM or online store.
Customers in India read WhatsApp messages far more than email or SMS, so order updates, reminders, offers and support work better there. With the API, messages go out from your verified business profile, using templates approved by Meta, without the risk of your number being blocked for bulk sending from a personal phone.
You pay Meta per delivered message, based on its category, and a monthly fee for the platform and support. We set up everything, from Meta business verification to your first broadcast, and support your team after launch.

Meta AdsWhatsApp Business API: frequently asked questions
What is the WhatsApp Business API?+
It is Meta's official WhatsApp Business Platform for medium and large businesses. It lets you send messages at scale, use chatbots, have many agents on one number and connect WhatsApp to your website, CRM or store, which the free Business app can't do.
How much does WhatsApp Business API cost in India?+
There are two parts: our platform fee, from ₹1,499 a month + GST, and Meta's per-message charges. For Indian numbers, Meta charges ₹0.8631 per marketing message and ₹0.115 per utility or OTP message, plus 18% GST.
Are customer replies free on WhatsApp?+
From 1 October 2026, each business number gets 1,000 free service messages a month. Replies beyond that are charged at the utility rate, ₹0.115 per message for Indian numbers. Messages customers send you are always free.
What changed in WhatsApp pricing on 1 October 2026?+
Service replies beyond 1,000 a month per number became chargeable, and utility templates sent inside the 24-hour customer service window stopped being free. Chats started from Click-to-WhatsApp ads stay free for 72 hours.
Do I have to switch to INR billing?+
Yes. Indian businesses must move their WhatsApp Business Accounts to INR billing by 31 December 2026. From 1 January 2027, Meta stops delivering messages from non-INR accounts of eligible Indian businesses. We handle the migration for our clients.
Can I use my existing WhatsApp number?+
Yes, but a number registered on the API can't be used on the WhatsApp or WhatsApp Business app at the same time. You can move an existing number after backing up chats, or use a new number for the API.
How long does setup take?+
Usually 2 to 5 working days. The main time is Meta's business verification and display name approval, which we handle for you.
What documents are needed for Meta business verification?+
Typically a business document showing your legal name and address, such as a GST certificate, incorporation certificate or Udyam certificate, plus a website or domain in the business name, and a phone number or email for verification.
Can I send bulk messages without getting blocked?+
Yes. On the API you send approved templates to customers who have opted in, within your messaging limit. Your limit grows as you send good-quality messages. Messaging people who didn't opt in can lower your quality rating.
What are message templates?+
Templates are pre-approved message formats needed to start a conversation or message a customer after 24 hours. Meta categorises them as marketing, utility or authentication, which decides the price.
What is the 24-hour customer service window?+
When a customer messages you, a 24-hour window opens in which you can reply freely, without a template. Under the October 2026 rules, the first 1,000 replies a month per number are free and the rest are charged.
What is the free entry point?+
When a customer messages you through a Click-to-WhatsApp ad on Facebook or Instagram, or your Page's WhatsApp button, and you reply within 24 hours, messages in that conversation are free for 72 hours.
Can I get the verified badge?+
Meta decides who gets a verified badge. We help you complete business verification and apply through the available options, such as Meta Verified for Business, but approval isn't guaranteed.
Does it work with my website or Shopify store?+
Yes. We connect WhatsApp to websites, WooCommerce, Shopify, CRMs and Google Sheets, so order updates, abandoned cart reminders and lead alerts go out automatically.
Can more than one person reply from the same number?+
Yes. Our shared team inbox lets several agents reply from one number, with chat assignment, labels, notes and reports.
Is there a minimum contract?+
Plans are monthly, with yearly billing available. Meta's message charges are paid as you use them.
Is GST charged on WhatsApp messages?+
Yes. 18% GST applies to Meta's message charges and to our platform fee. Registered businesses can usually claim it as input tax credit.
What can't be promoted on WhatsApp?+
Meta's Commerce Policy restricts products such as weapons, drugs, tobacco, alcohol, adult products and some financial and medical services. We check your use case before setup.
