Updated: October 9, 2026
What's the difference between WhatsApp and WhatsApp Business?
WhatsApp Business adds business tools: business profile, catalog, cart, greeting and away messages, quick replies, lists and a short link with QR. Both are free, but you can't use the same number on both at the same time.
What is the WhatsApp Business API?
It's the official way to connect WhatsApp to software: several agents on one number, chatbots and AI, integrations and bulk sends with approved templates. You use it through a platform and Meta charges per message by country.
Can I use the app and the API with the same number?
Yes, with coexistence: you connect your WhatsApp Business app number to an API platform and keep using the app on your phone.

Quiz: which do you need?
Answer the 4 questions to see your recommendation.
Set up your profile, quick replies and the away message properly. When you grow, you can connect the same number to the API without leaving the app.
Several people, high volume or automation: with ChatSales you connect your number (with coexistence you keep using the app), work from one shared inbox and an AI assistant answers the usual questions.
Signs you've outgrown the app
- You share the business phone or spend the day on WhatsApp Web with 4 sessions open.
- Customers wait hours because nobody knows who owns each chat.
- You lose sales at night or on weekends.
- You need to know how many chats end in a sale and which ad works.
What the API costs
Meta charges per message by country and category (marketing, utility, authentication or service); check your country with the API pricing calculator and what changed on October 1 in Meta's new pricing. You also pay for the platform (see ChatSales pricing).

Frequently asked questions
Is the WhatsApp API free?
No. Meta charges per message by country and category, and you need a platform to use it.
Can I switch from WhatsApp to WhatsApp Business without losing chats?
Yes, WhatsApp lets you move your account information. Back up first.
Can I go back from WhatsApp Business to WhatsApp?
Yes, but features like the catalog and collections don't transfer.
What is coexistence?
Using the same number on the WhatsApp Business app and the API at the same time, connected to a platform. According to Meta, once it's on, the app's broadcast lists become read-only (broadcasts go through the API) and your linked devices are unlinked, though you can re-link them; greeting, away, quick replies, labels and catalog stay the same in the app.
