Quick answer
To get the WhatsApp Business API in India, sign up through a Meta partner such as QuickMessage, connect or create your Meta business portfolio, add a phone number that can receive an SMS or voice call, set your display name, and get your first message templates approved. You can start messaging the same day. New businesses can message 250 unique customers a day at first; verifying your business unlocks 2,000, and Meta raises the limit further as your message quality stays high.
The WhatsApp Business API (Meta now calls it the WhatsApp Business Platform) is how Indian businesses send order updates, OTPs, reminders and campaigns at scale, run chatbots and let a whole team answer from one number. Getting access is easier than most people expect, but a few details, like your phone number and display name, decide whether setup takes ten minutes or ten days.
This guide walks through every step, what you need before you start, how the sending limits work and the mistakes that most often slow businesses down.
What you need before you start
| Requirement | What it means |
|---|---|
| A Meta business portfolio | Your Facebook Business Manager account. You can create one during signup if you do not have it. |
| A phone number you own | It must be able to receive an SMS or a voice call for the verification code. Landlines and toll-free numbers work if they can take calls from international numbers. Short codes are not supported. |
| A display name | The business name customers see. It should clearly match your brand, website and documents. |
| A business website | A live site that shows your business name, what you sell and how to contact you. It helps with both verification and display name review. |
| Business documents (for verification) | Not needed to start, but needed to grow beyond 250 customers a day. Commonly accepted documents in India include a GST certificate, Certificate of Incorporation, Udyam (MSME) registration or a shop and establishment certificate in your legal business name. |
How to get WhatsApp Business API: 7 steps
Step 1: Choose a Meta partner
Most businesses get the API through a Meta Business Partner, because Meta's own Cloud API gives you the connection but not the tools: no shared inbox, no campaign manager and no chatbot builder. A partner like QuickMessage handles the signup with you and gives you those tools on top. Compare the platform fee, the per-message rates and the features before you choose; see our list of WhatsApp Business API providers in India.
Step 2: Connect your Meta business portfolio
Your partner opens Meta's signup window (called Embedded Signup). Log in with Facebook, then select your existing business portfolio or create a new one. Choose carefully: once a number is registered, it stays with that portfolio.
Step 3: Add and verify your phone number
Enter the number and confirm it with the code Meta sends by SMS or voice call. You must also set a six-digit two-step verification PIN; keep it safe, because you need it to move the number later. New business portfolios can register two phone numbers at first.
Step 4: Set your display name and profile
Add your display name, logo, description, address and website. Use the same name that appears on your website and documents. Meta checks the display name automatically when you reach a higher messaging limit, and a rejected name can be corrected or appealed.
Step 5: Verify your business with Meta
In your business portfolio's security settings, start Business Verification and upload a document that shows your legal business name and address. The name must match what you entered exactly. Review time varies, so start this early. Verification is the quickest way to move from 250 to 2,000 customers a day.
Step 6: Create your message templates
To message customers who have not written to you in the last 24 hours, you need templates approved by Meta. Pick the right category (marketing, utility or authentication), keep the wording clear and avoid placeholders at the start or end. Our guide to template rejection reasons covers the common mistakes.
Step 7: Go live and grow your limit
Add a payment method or top up your wallet, import contacts who have opted in, and send your first campaign or connect your chatbot and team inbox. Keep quality high and Meta raises your limit step by step.
How the sending limit grows
The messaging limit is the number of unique customers your business can message outside a customer service window in a moving 24-hour period. It is set for your whole business portfolio and shared by all its phone numbers.
| Limit | How you get there |
|---|---|
| 250 | Every new business portfolio starts here. |
| 2,000 | Verify your business (or have your partner verify it), or deliver 2,000 high-quality template messages to unique customers within 30 days. |
| 10,000 | Automatic, while your message quality is high and you have used at least half of your limit in the last 7 days. |
| 100,000 | Automatic, on the same conditions. |
| Unlimited | Automatic, on the same conditions. |
When you qualify, Meta raises the limit by one level, usually within 6 hours. Source: Meta's messaging limits documentation.
Can you use your existing WhatsApp number?
Yes, in one of two ways:
- Move it to the API. A number already registered on WhatsApp must be deleted from the WhatsApp or WhatsApp Business app first, then registered on the API. Back up any chats you want to keep, because they do not move across.
- Keep using the WhatsApp Business app too (coexistence). If the number is on the WhatsApp Business app (version 2.24.17 or later), Meta's signup can connect it to the API while you keep using the app on your phone, with the option to sync recent chat history. Numbers used this way have a fixed sending speed of 20 messages per second, which is fine for most small and mid-sized businesses.
Our guide to using your existing number for WhatsApp Business API covers every option, including switching from another provider. Not sure which is right for you? Our comparison of the WhatsApp Business API and the WhatsApp Business app explains the trade-offs.
What it costs
There is no fee from Meta to get access. You pay two things: your provider's platform plan, and per-message charges for the messages you send, which depend on the message category. On QuickMessage, plans start at ₹999/month. Since October 1, 2026, Meta also charges for service replies after the first 1,000 free each month per number; our guide to service message charges explains the change, and the pricing page lists every rate.
Common mistakes that slow down setup
- Using a number that is still active on WhatsApp without deleting it or choosing coexistence.
- A display name that does not match the brand on your website and documents, such as a generic name like "Best Offers India".
- A legal name mismatch between the business portfolio and the document uploaded for verification.
- A website with no business details, such as a page under construction or no contact information.
- Messaging people who have not opted in, which lowers your quality rating and stops your limit from growing.
- Losing the two-step verification PIN, which you need to move the number later.
Frequently asked questions
How long does it take to get WhatsApp Business API?
Signup and phone number setup can be done the same day. Business verification and template approval are reviewed by Meta and can take longer, so start verification early.
Is business verification mandatory?
Not to start. Without it you can message up to 250 unique customers a day outside a customer service window. Verifying your business is the quickest way to reach 2,000 and keep growing.
Can I get WhatsApp Business API without GST?
Yes. Other documents in your legal business name, such as a Certificate of Incorporation, Udyam registration or a shop and establishment certificate, are commonly accepted for verification. Meta reviews each case.
Can I use the same number on the WhatsApp Business app and the API?
Yes, with coexistence, if the number is on the WhatsApp Business app version 2.24.17 or later. Otherwise the number must be deleted from the app before it is registered on the API.
How many phone numbers can I add?
New business portfolios can register two phone numbers at first. The messaging limit is shared by all numbers in the portfolio.
