WhatsApp Business API in India

Reach customers where they already reply. Broadcasts, order updates and OTPs from your own systems, on the official Meta platform. Meta's message charges billed directly by Meta.

Why WhatsApp

Send your campaigns on WhatsApp, and answer every reply

Use the WhatsApp Business API to broadcast offers, order updates and reminders to your whole customer list, then handle everyone who replies from one shared inbox. It runs inside the SmsHorizon panel you already use for SMS, on the same wallet and the same reports.

Your message lands in the app your customer already checks all day, next to messages from friends and family. Send images, PDFs and tappable buttons instead of 160 plain characters, and let your whole team reply from one number. Keep SMS for the OTPs and critical alerts that must reach every handset, and let WhatsApp carry the conversations.

Message charges

Message charges are billed by Meta

Meta charges per delivered template message, not per conversation, and bills you directly for it. You always pay the latest published WhatsApp rate, with nothing added by us. Our plan covers the platform.

Message categoryWhat it is forRate per message
MarketingOffers, launches, re-engagementChargeable
UtilityOrder updates, payment and account alertsChargeable
AuthenticationOTPs and login verificationChargeable
ServiceYour replies inside a 24-hour customer windowFree

Rates are set by Meta and billed directly to you at the latest published WhatsApp rate for India, so you always pay the current rate rather than one quoted here. Utility messages sent inside an open 24-hour customer service window are free, and a click-to-WhatsApp ad opens a 72-hour window in which all messages are free. Higher monthly volumes unlock lower utility and authentication rates. Ask us for today's rate card.

Getting live

From signup to first message

You can send on day one. Verification and the badge come later, and neither of them blocks you from starting.

Pick a number

It must not be active on the consumer WhatsApp app. A number on the WhatsApp Business app can be moved across without losing history. Most businesses start with a fresh number and keep the old one for walk-in chats.

Connect through Embedded Signup

Meta's official flow runs inside our panel. You approve access, pick your display name, and your WhatsApp Business Account is created and linked.

Minutes

Submit your first templates

We draft them with you so they clear review the first time. Meta reviews each template and returns a decision.

Up to 24 hours

Start sending

New accounts can start conversations with 250 unique customers in any rolling 24 hours. Replies inside an open customer window do not count against that.

Same day

Complete business verification

This lifts you to 2,000 unique customers a day, raises your number cap from 2 to 20 and your template cap from 250 to 6,000. We prepare the document pack with you.

Meta decides in up to 14 working days

Scale up automatically

Once you are sending quality messages and using at least half your limit, Meta raises you through 10,000, 100,000 and finally unlimited. Upgrades apply within 6 hours.

The blue tick

Straight talk about the verified badge

The badge most people still call the green tick is now a blue checkmark, and it is granted through an Official Business Account. It is worth being blunt here, because this is the single most oversold item in the Indian WhatsApp market: nobody can guarantee you the badge, and nobody can guarantee a date. Meta publishes no turnaround time for the decision, and a rejected application cannot be resubmitted for 30 days.

The good news is that it is no longer a judgement about how famous your brand is. Older guidance said you had to be a "notable business" with press coverage. Meta's current request page instead publishes a checklist that an ordinary business can work through:

RequirementWhat it means
Policy complianceNo standing violations of the WhatsApp Business Messaging Policy
30 days on the platformYour number has been registered for at least a month
Verification or volumeCompleted business verification, or 1,000 conversations over 30 consecutive days
Two-step verificationEnabled on the business number
Approved display nameYour display name has passed Meta's review

The realistic floor is therefore about 30 days, and only if verification and display name approval both land inside that window. On the Growth and Business plans we prepare and submit the application for you, and tell you honestly when you are not yet eligible rather than filing an application that burns a 30-day cooldown.

Compliance

WhatsApp and Indian rules

No DLT registration, and that is official

DLT registration is a TRAI requirement under TCCCPR that governs SMS and voice carried over telecom networks. WhatsApp is an over-the-top service, and TRAI's regulations, including the Second Amendment of February 2025, exclude OTT providers from that scope. There is no PE ID to obtain, no header to register and no template scrubbing with Airtel, Jio or Vi. If you already send SMS through us, your DLT setup is untouched by adding WhatsApp. Be careful of anyone selling you "DLT registration for WhatsApp"; it does not exist.

What does apply: Meta's opt-in rules and DPDP

No DLT does not mean no rules. Meta requires that the customer gave you their number and opted in to hear from you on WhatsApp, with your business named and a way to opt out. You can collect that consent on your website, by SMS, on the phone, in person or on paper, and the burden of proving it sits with you. On top of that sits India's own DPDP framework: the Digital Personal Data Protection Rules were notified in November 2025, they are channel-agnostic, and they require consent that is free, specific, informed and backed by a plain-language notice. The main obligations phase in from May 2027, so the sensible move is to build a clean opt-in trail now.

Quality rating, and how numbers actually get banned

Meta scores every number green, yellow or red based on how often recipients block or report you over a trailing week. A poor rating no longer drags your messaging limit down, but it does stop you moving up, and sustained abuse runs an enforcement ladder: a warning, then a block on template sends, then a block on all messaging, then permanent disablement. Sending to purchased lists and dressing marketing up as utility templates are two of the fastest ways onto that ladder. This is also why we will not support unofficial bulk WhatsApp sender tools at any price.

App vs API

Which WhatsApp do you actually need?

Most businesses start on the free app and hit a wall. Here is exactly where that wall is.

Indian businesses cannot create a WhatsApp Business Account directly in Meta Business Suite. Meta requires you to onboard through a solution provider, which is the route we handle for you.

FAQs

WhatsApp Business API questions

What is the WhatsApp Business API?
The WhatsApp Business API is Meta's platform for businesses that need to message customers at scale from their own systems. Unlike the free WhatsApp Business app, it has no chat interface of its own. You connect it to a platform like SmsHorizon, then send template messages, run broadcasts and handle two-way conversations through a web panel or a REST API. It supports multiple users on one number and integrates with your CRM, website or order system.
How much does the WhatsApp Business API cost in India?
There are two separate costs. First, a platform subscription: our plans start at ₹2,000 per quarter, or ₹6,000 per year with the 25% yearly discount, plus 18% GST. Second, Meta's own per-message charge, which Meta bills you directly at its latest published WhatsApp rate for India. We add nothing to it. Service messages, meaning replies inside a 24-hour customer service window, are free. Ask us for the current rate card.
Does the WhatsApp Business API need DLT registration?
No. DLT registration is a TRAI requirement under TCCCPR that applies to SMS and voice sent over telecom networks. WhatsApp is an over-the-top service governed by Meta's own policies, and TRAI's regulations exclude OTT providers. There is no PE ID, no header registration and no template scrubbing with the telecom operators. You do still need Meta's approval for your message templates, and India's DPDP rules on consent apply to your marketing regardless of channel.
How do I get the green tick on WhatsApp?
The verified badge, now a blue checkmark rather than a green tick, comes from being granted an Official Business Account. Meta publishes a checklist rather than judging how famous your brand is: your account must comply with the WhatsApp Business Messaging Policy, have been registered on the platform for at least 30 days, have completed business verification or sent 1,000 conversations over 30 consecutive days, have two-step verification enabled, and have an approved display name. You then apply directly in WhatsApp Manager. Meta publishes no turnaround time, and if an application is rejected you must wait 30 days to reapply. Any provider guaranteeing a specific date is guessing.
How long does WhatsApp Business API onboarding take?
You can start sending on the same day. Since May 2022 Meta no longer requires business verification or display name approval before you send your first message. Connecting your number through Meta's Embedded Signup takes a few minutes, and message templates are reviewed within 24 hours. Business verification, which lifts your limits and is a prerequisite for the verified badge, takes up to 14 working days for Meta to decide.
How many messages can I send per day?
Meta sets a messaging limit that controls how many unique customers you can start conversations with in a rolling 24-hour period. New accounts start at 250, then move up through 2,000, 10,000, 100,000 and finally unlimited. Since 7 October 2025 this limit is set per business portfolio and shared across every number in it, not per phone number. Upgrades are automatic when you send high-quality messages and use at least half your current limit, and they apply within 6 hours. Replies inside an open customer service window do not count against the limit.
Can I use my existing WhatsApp number for the API?
Only if it is not currently active on the consumer WhatsApp app. A number already registered on WhatsApp Messenger has to be deleted from that account first, which erases its chat history. A number on the WhatsApp Business app can be moved across through a partner without losing message history. In practice most businesses prefer to start with a fresh number and keep the existing one for walk-in conversations.
What is the difference between the WhatsApp Business app and the API?
The app is free, runs on one phone, and is designed for a single person answering chats manually. The API has no app of its own, supports multiple team members on the same number, sends approved template messages in bulk, and connects to your own software. The app cannot broadcast beyond small labelled lists and cannot be automated. If you need order updates, OTPs or campaigns triggered by your system, you need the API.
What are message templates and why do they get rejected?
A template is a pre-approved message format you must use to start a conversation outside an open 24-hour window. Templates fall into three categories: marketing, utility and authentication. Meta reviews each one within 24 hours. Common rejection reasons are mismatched or non-sequential variable placeholders, variables sitting at the very start or end of the message, special characters inside variables, asking for sensitive details such as full card or national ID numbers, duplicate templates, and promotional content submitted as utility. We draft and fix templates for you on the Growth and Business plans.
Do I need customer opt-in before messaging on WhatsApp?
Yes. Meta requires that the customer gave you their number and opted in to receive WhatsApp messages from you, with your business clearly named and an opt-out available. The opt-in can be collected on your website, by SMS, over the phone, in person or on paper, and does not have to be collected inside WhatsApp itself. The burden of proof sits with you as the sender. Separately, India's DPDP Rules 2025 require free, specific and informed consent for personal data used in marketing, with core obligations starting 13 May 2027.
Can I send WhatsApp broadcasts to a purchased contact list?
No, and you should not try. Messaging people who never opted in drives blocks and reports, which pushes your quality rating down and triggers Meta's enforcement ladder: warnings, then blocks on template sends, then blocks on all messaging, then permanent disablement of the number. Bulk WhatsApp sender tools that work outside the official API get numbers banned outright. We only support the official API and will help you build a clean opt-in list instead.
Can I use the same platform for SMS, RCS and WhatsApp?
Yes. WhatsApp runs from the same SmsHorizon panel and the same account you already use for SMS and RCS, with one wallet and one set of reports. Many businesses use WhatsApp for rich two-way conversations and keep SMS as the guaranteed-reach fallback for OTPs and critical alerts, since SMS reaches every handset without requiring an app.
