Is the WhatsApp Business API free?

No. Access to the platform has no app to buy, but Meta charges for certain messages, mainly business-initiated template messages such as marketing, utility and authentication, at rates that vary by country and category. Business Solution Providers and CRM tools usually add their own fees. Replies inside the customer service window have generally been free. Check Meta's current pricing page before budgeting.

Can I use the same number on the WhatsApp Business app and the API?

Traditionally, moving a number to the API meant it stopped working in the app. Meta has since introduced a coexistence option, offered through some providers, that lets a number use both the app and the API, with limitations. Availability and features vary, so confirm with your provider before migrating, and back up important chats first.

How many people can use the WhatsApp Business app at once?

The app supports a main phone plus a limited number of linked devices, which suits an owner or a small team. There is no proper assignment, queue or audit trail, so it gets messy once several people reply. If you need many agents, routing and reporting, the API with a shared inbox or CRM is the better fit.

Do I need a green tick or verified badge to use the API?

No. You need a Meta Business account, and you will usually complete business verification to raise messaging limits and unlock features. Verified badges are separate and optional; Meta has changed how they work over time, including through Meta Verified for businesses. Check Meta's current verification options and eligibility rules for your country.

Can I send bulk promotional messages on WhatsApp?

On the app, broadcast lists only reach contacts who have saved your number, and there are practical limits. On the API, you can send approved marketing templates at scale, but only to people who have opted in, and within your account's messaging limits. Low-quality or unwanted messages lead to blocks and reports, which can restrict your number.

WhatsApp Business App vs WhatsApp Business API: Which Does Your Business Need?

Short answer: Use the WhatsApp Business app if one person or a small team handles chats and volume is manageable. Move to the WhatsApp Business API (Business Platform) when several people need a shared inbox, you want chats flowing into a CRM, or you need automation, templates and campaign tracking at scale.

Many businesses in India and the UAE start on the free app and stay there too long, or jump to the API before they have a process to automate. The right choice depends on team size, message volume and how much of your sales or service runs through WhatsApp.

A note on facts: Meta updates WhatsApp features, policies and pricing regularly. This guide describes the products at the time of writing. Check Meta’s current documentation before you decide.

What is the difference between the WhatsApp Business app and the API?

The WhatsApp Business app is a free phone app for one business number, with a catalog, labels and quick replies. The WhatsApp Business API, now called the WhatsApp Business Platform, has no app of its own: it connects your number to software such as a CRM or shared inbox through Meta’s Cloud API or a Business Solution Provider.

	WhatsApp Business app	WhatsApp Business API (Platform)
What it is	Mobile and desktop app	Programmatic access via Meta Cloud API or a provider
Best for	Owner-led or small teams	Multi-agent teams and higher volume
Users	Main phone plus limited linked devices	Many agents through a shared inbox or CRM
CRM integration	Manual logging or extensions	Native: messages create and update records
Outbound messages	Manual; broadcast lists to saved contacts	Approved templates to opted-in contacts
Automation	Greeting, away messages, quick replies	Chatbots, routing, reminders, CRM triggers
Reporting	Basic message statistics	Whatever your inbox or CRM reports
Ad tracking	Pre-filled message per campaign	Click-to-WhatsApp referral data per chat
Cost model	Free app	Meta message charges plus provider or CRM fees
Setup	Minutes	Meta Business account, number registration, provider setup

Which features does each option actually give you?

The app gives you a business profile, catalog, labels, quick replies, greeting and away messages, and broadcast lists. The API gives you none of that out of the box; instead it lets your software send and receive messages, so features depend on the inbox, CRM or chatbot you connect to it.

That second point surprises people. The API is infrastructure, not a product. You will use it through something:

A shared inbox from a Business Solution Provider, with assignment, tags and notes.
Your CRM, so chats sit on the customer record next to deals, quotes and tasks. See our CRM development work.
A custom integration that links WhatsApp to your ERP, booking system or order flow, as in WhatsApp to ERP orders.

So when you compare “the API”, you are really comparing providers and the tools wrapped around Meta’s platform. Questions worth asking any provider:

Can each agent see the full conversation history, including chats handled by colleagues?
Can chats be assigned by rule, such as product, branch or language, and reassigned with notes?
Does it sync contacts, owners and stages with your CRM both ways, or only push messages one way?
How are template submissions, opt-in records and quality alerts handled?
Can you export your data if you change provider later?

The answers matter more than the logo. A good inbox on the API should make every chat visible, owned and measurable.

How do templates, opt-in and the service window work?

On the API, when a customer messages you, a customer service window opens and you can reply freely for that period. Outside it, you can only send pre-approved message templates. Business-initiated messages also require the customer’s opt-in, which you should record against each contact.

Templates are grouped into categories, currently marketing, utility and authentication, and Meta reviews them before use. Good habits:

Keep utility templates genuinely transactional: order confirmations, appointment reminders, delivery updates.
Write marketing templates for people who asked to hear from you, not purchased lists.
Store where and when each contact opted in, such as a website checkbox or the customer messaging first.
Watch your quality rating. Blocks and reports can lower your limits.

On the app, none of this is enforced the same way, but Meta’s policies still apply, and spammy broadcasts get numbers restricted.

How much does each option cost?

The app is free. The API charges per message under Meta’s pricing, which varies by country and message category, with business-initiated templates billed and replies within the service window generally free. Providers and CRMs add their own fees. Prices change, so check Meta’s current rate card and your provider’s plan.

Meta has changed its pricing model before, from conversation-based to per-message charges, so treat any figure you read online with care, including in older articles. When budgeting, estimate:

How many marketing, utility and authentication templates you will send each month, and to which countries.
Your provider’s platform fee, per-agent seats, or markup on Meta charges.
CRM or integration build and support costs.

Compare that with the cost of leads lost on personal phones. Our post on why WhatsApp leads go cold covers where those losses happen.

What does verification involve?

Using the API requires a Meta Business account, a phone number not tied to a personal WhatsApp account, and a display name that follows Meta’s guidelines. Business verification, done in Meta’s Business tools with company documents, raises messaging limits and unlocks features. Verified badges are a separate, optional layer.

Keep your legal name, website and address consistent across Meta, your website and registration documents. Mismatches are the most common reason verification stalls. Meta’s badge programmes have changed over time, so check what is currently available for businesses in your country.

When should you switch from the app to the API?

Switch when the app’s limits start costing you sales: several people share one phone, chats are not reaching your CRM, you need assignment and response tracking, or you want reminders, automation and ad attribution. If one person handles everything comfortably, the app is still the sensible choice.

Signs it is time:

Staff reply from personal numbers because the business phone is busy.
Nobody can tell who answered a customer, or whether anyone did.
Leads are retyped from chats into a spreadsheet or CRM.
You run Click-to-WhatsApp ads and cannot connect chats to revenue.
You need appointment reminders or order updates sent automatically.
You serve customers in both India and the UAE across time zones and need coverage rules.

How do you migrate from the app to the API?

Plan the migration like a small project: choose a provider or Cloud API, prepare your Meta Business account and verification, decide whether to move your existing number or use a new one, set up templates and inbox routing, then train the team and announce the change before cutover.

Migration checklist:

Add chatbots and AI only after the basics run. Automation can classify enquiries and draft answers, but a person should own pricing and commitments. See AI automation for where that fits.
