10. Frequently Asked Questions (FAQ)
1. What is WhatsApp Business API?
The WhatsApp Business API (also called WhatsApp Business Platform) is an official
solution developed by Meta for medium and large businesses to communicate with
customers on WhatsApp at scale. Unlike the standard WhatsApp Business App -
which is designed for small businesses with a single user - the API is built
for high-volume, automated, and multi-agent communication.
In simple terms, it is a
programming interface (API) that allows businesses to connect WhatsApp with
their existing software - CRMs, ERPs, e-commerce platforms, customer support
tools - and send messages
programmatically.
With WhatsApp Business API,
businesses can:
•
Send bulk transactional
messages (order updates, OTPs, payment alerts)
•
Run outbound marketing
campaigns with approved message templates
•
Deploy AI-powered chatbots
for 24/7 customer support
•
Manage thousands of
customer conversations across multiple agents
•
Integrate with CRM, payment
gateways, and e-commerce platforms
•
Get verified with an
Official Business Account (green tick badge)
|
Quick Stat: WhatsApp messages have a 98% open rate and a 45–80%
click-through rate — far higher than email or SMS marketing. |

Verdict: If your business handles more than 50 customer
conversations per day, or you want to run automated campaigns and integrate
WhatsApp with your systems, the WhatsApp Business API is the right choice. |
3. How to Create a WhatsApp Business Account
Setting up a WhatsApp
Business account and accessing the API
involves a few key steps. Here is the complete 2026 process:
Step 1: Create a Meta Business Manager Account
Visit business.facebook.com and
create a Meta Business Manager account. This is the foundation for your
WhatsApp Business account. Provide accurate business details — your registered
name, address, and website.
Step 2: Verify Your Business on Meta
Meta requires business
verification to use the API. Submit your business registration documents (GST
certificate, incorporation certificate, etc.). Verification usually takes 2–5
business days.
Step 3: Choose a WhatsApp Business Solution Provider (BSP)
You need an authorised WhatsApp
Business Solution Provider (BSP) like
MySmsMantra to access the API. A BSP handles the technical setup, onboarding,
and ongoing support so you can go live without managing complex infrastructure.
Step 4: Set Up Your WhatsApp Business Account (WABA)
Through your BSP, create your
WhatsApp Business Account (WABA) and link it to your Meta Business Manager.
Register the phone number you want to use — this can be a mobile number,
landline, or toll-free number.
Step 5: Phone Number Verification
WhatsApp sends a 6-digit OTP to
verify your phone number. Once verified, your number is officially registered
on the WhatsApp Business Platform.
Step 6: Create and Get Message Templates Approved
All outbound messages on WhatsApp
Business API must use pre-approved templates. Submit your templates (for order
updates, appointment reminders, marketing offers, OTPs, etc.) to Meta for
approval. Approval typically takes a few hours to 24 hours.
Step 7: Integrate and Go Live
Your BSP will provide you with API
credentials and documentation. Integrate the API with your CRM, website, or
back-end systems. Test the integration and go live within minutes.
|
Pro Tip: Through MySmsMantra, you can complete WhatsApp Business
account onboarding in as little as 10–15 minutes with guided support at every
step. |
4. Key Features of WhatsApp Business API
The WhatsApp Business API is
packed with features that make it the most powerful business messaging platform
available in 2026:
Verified Business Profile (Green Tick)
Get your business officially
verified by WhatsApp with the coveted green
tick badge. This instantly builds trust -
customers know they are chatting with a legitimate business, not a scammer.
Automated Message Templates
Send pre-approved, structured
messages for transactional notifications, marketing campaigns, OTPs,
appointment reminders, payment alerts, shipping updates, and more. Templates
support text, images, buttons, and CTAs.
Interactive Messages
Use interactive message types -
list messages, reply buttons, quick replies, and call-to-action buttons - to
guide customers through a conversation flow and drive conversions.
WhatsApp Chatbot / Answer Bot
Deploy AI-powered chatbots to
handle frequently asked questions, qualify leads, process orders, and provide
round-the-clock customer support — reducing manpower costs by up to 60%.
Multi-Agent Inbox
Assign conversations to different
team members, tag chats, track response times, and manage your entire WhatsApp
support operation from a central dashboard with multiple agents logged in
simultaneously.
Rich Media Support
Send and receive images, PDFs,
Excel files, Word documents, videos, audio messages, location pins, and contact
cards - making WhatsApp a complete business communication platform.
Broadcast Messaging at Scale
Unlike the WhatsApp Business App
(limited to 256 contacts), the WhatsApp
Business API allows you to send approved
template messages to unlimited customers simultaneously — making it ideal for marketing
campaigns, festival offers, product launches, and service alerts.
Delivery and Read Receipts
Track every message with detailed
delivery reports — sent, delivered, read, and failed. Set up fallbacks to SMS
if a WhatsApp message fails to deliver.
WhatsApp Payments (India)
In India, WhatsApp supports native
UPI-based payments within the chat - customers can browse your catalog, ask
questions, and complete purchases without leaving WhatsApp.
5. WhatsApp Business API Pricing in India (2026)
Starting July 1, 2025, Meta
shifted to a per-message pricing model for the WhatsApp Business Platform. This replaced the
older per-conversation pricing structure. Here is how it works:
|

To get the best results from your
WhatsApp Business account, follow these proven best practices:
11. Complete your business profile: Add your logo, business hours, website, address, and
catalog. A complete profile builds trust and reduces basic enquiries.
12. Always get opt-in consent: Only message customers who have opted in to receive
WhatsApp communications from your business.
13. Use interactive templates: Replace plain text messages with buttons and quick
replies to guide customer journeys and increase conversions.
14. Respond within 24 hours: Customer-initiated conversations are free for 24 hours.
Use chatbots to respond instantly and keep this window open.
15. Personalise your messages: Use merge fields to include the customer's name, order
number, or location in every message.
16. Track performance metrics: Monitor delivery rates, read rates, and reply rates. Drop
templates with low engagement.
17. Avoid spam-like behaviour: Sending irrelevant or too-frequent messages leads to
blocks and can get your WhatsApp Business account restricted by Meta.

Frequently Asked Questions (FAQ)
Here are answers to the most
commonly searched questions about WhatsApp Business API and WhatsApp Business
accounts:
Q1. What
is the difference between WhatsApp Business and WhatsApp Business API?
WhatsApp Business is a free app
designed for small businesses, allowing one user to manage conversations
manually. WhatsApp Business API is a paid, scalable solution for
medium-to-large businesses that enables automation, chatbots, CRM integration,
multi-agent support, and bulk messaging with no contact limits.
Q2. How
do I create a WhatsApp Business account?
You can create a basic WhatsApp
Business account by downloading the WhatsApp Business app from the Google Play
Store or App Store, verifying your business phone number, and setting up your
profile. To access the API, you need to register through a WhatsApp Business
Solution Provider (BSP) like MySmsMantra and complete the Meta Business
Verification process.
Q3. Is
WhatsApp Business API free?
The WhatsApp Business API itself
is not free. Meta charges a per-message fee for marketing, utility, and
authentication messages. However, messages received from customers
(user-initiated) within a 24-hour window are free. Your BSP may also charge a
platform fee. Contact MySmsMantra for a transparent pricing breakdown.
Q4. Can
I use my existing number for WhatsApp Business API?
Yes. You can use your existing
mobile number, landline number, or toll-free number for the WhatsApp Business
API. If the number is already on personal WhatsApp or the WhatsApp Business
App, it must be migrated. MySmsMantra can guide you through this process.
Q5. How
do I get the WhatsApp green tick (verified badge)?
The WhatsApp green tick (Official
Business Account) is granted by Meta after you complete Meta Business
Verification and demonstrate that your business is a well-known brand. You can
apply through your Meta Business Manager account. MySmsMantra can assist with
the application and increase your approval chances.
Q6. What
is a WhatsApp Business Solution Provider (BSP)?
A BSP (Business Solution Provider)
is an officially authorised partner of Meta/WhatsApp that provides access to
the WhatsApp Business API. BSPs handle onboarding, technical integration,
template management, and support. MySmsMantra is an authorised BSP operating in
India.
Q7. Can
WhatsApp Business API be used for bulk messaging?
Yes. With WhatsApp Business API,
you can send approved template messages to an unlimited number of contacts
simultaneously. Unlike the WhatsApp Business App (which limits broadcasts to
256 contacts), the API has no such restriction - making it ideal for
large-scale marketing campaigns.
Q8. How
long does it take to set up WhatsApp Business API?
With MySmsMantra, the basic setup
takes as little as 10–15 minutes. Full onboarding -including Meta Business
Verification, phone number registration, and template approval - typically
takes 2–5 business days depending on how quickly Meta processes your documents.
Q9. Is
WhatsApp Business API safe and GDPR compliant?
Yes. WhatsApp Business API uses
end-to-end encryption for messages. Businesses are responsible for obtaining
proper opt-in consent from customers before messaging them, which aligns with
GDPR and India's PDPB (Personal Data Protection Bill) requirements.
