Quick answer
Should I use the WhatsApp Business app or the API after 1 October 2026? It depends on volume, team and software needs. Meta’s pages say the API charges per delivered message by category, with 1,000 free delivered service messages per number each month from 1 October 2026. WhatsApp’s help pages say business broadcasts are exclusively on the Business app and sent for a fee. Nothing we read says everyone must move. Use the Switch Test: Volume, Voices, Variety.

Scope note: Where the pages we read are silent about the app, the table says so. We did not test either product on a live account and did not read India rate cards.
Picture Farah, who runs a home bakery from her phone. Last month she had 40 chats a day and answered all of them herself.
Then a friend told her, “WhatsApp is charging now, you must move to the API.” She is not sure that is true, and she does not want to guess.
Meta and WhatsApp publish separate pages for the app and the Platform. Neither says everyone must move. They do describe different prices.
Below is a plain comparison from those pages, a quick fit check and five questions to ask any provider.
What the pages say about each
Meta and WhatsApp describe two different things. The WhatsApp Business app is what you open on your phone. The WhatsApp Business Platform is the API a provider connects for you.
| WhatsApp Business app | WhatsApp Business Platform (API) | |
|---|---|---|
| Who it is for | Owners and small teams on a phone | Businesses that connect software through a provider |
| Business broadcasts | Exclusively on the Business app, sent for a fee, charged on delivered messages | Not described on the broadcast pages. The API has its own categories |
| Service replies | The pages we read describe no per message charge for replies | Charged after 1,000 delivered service messages per number each month, from 1 Oct 2026 |
| Marketing, utility, authentication | Not described on the pages we read | Charged per delivered message by category and country |
| Click to WhatsApp ad window | Not described on the pages we read | Free entry point window up to 7 days after a timely reply |
| AI replies | Not described on the pages we read | Meta Business Agent messages charged by tokens, about 4 to 5 US cents |
The sources are Meta’s pricing page for the Platform and WhatsApp’s help pages for business broadcasts. Where a page is silent, the table says so. We did not test the app or the API on a live account.
Reality check
“Everyone must move to the API now.”
Nothing on the pages we read says that. They describe the API’s pricing and a separate fee for broadcasts on the app. The right tool depends on your volume, team and need for software.

5 questions to ask a provider
Free kit: 5 provider questions
1 · The price question
What do you charge on top of Meta’s per message price, and is it per message or a monthly fee?
2 · The free tier question
How many delivered service messages did my number send last month, and can I see it by week?
3 · The billing question
How do I add a payment method in Billing Hub, and what happens to my messages if it is missing?
4 · The exit question
Can I export my chats and contacts if I leave, and in what format?
5 · The handover question
Can a person take over from automation in one tap, and can I turn automation off for some chats?
Question 2 matters most this month. Meta’s free tier is 1,000 delivered service messages per number.
Questions owners ask about the app and the API
Do I have to move to the WhatsApp API?
Nothing on the Meta and WhatsApp pages we read says every business must move. They describe API pricing and a separate broadcast fee on the Business app.
What changed on 1 October 2026 for the API?
Meta’s pricing page says service messages are charged after 1,000 delivered per business phone number each month.
Are broadcasts on the API?
WhatsApp says business broadcasts are exclusively on the Business app.
Is the Business app free to use?
The pages we read describe fees for business broadcasts on the app. They do not describe a per message fee for ordinary replies. Check the app for current terms.
What does the API add?
The pages describe per message categories, a free entry point window for ad chats and an AI agent category with token pricing.
How do I choose?
Use the Switch Test: Volume, Voices, Variety. Then compare providers with five questions.
Where do I start?
Count your chats and team size this week. Do not switch just because a price changed.
Pick the tool for your volume and your team, not for the headline.
