Updated on October 28, 2026<\/em><\/p>\n\n\n\n

This page collects the 40 most common questions about the official WhatsApp Business API, with short, direct answers grouped by topic: access, pricing, templates, limits, coexistence, technical setup and accounts. Each answer stands on its own and links to the article that goes deeper. Prices and rules were checked against Meta’s official documentation on October 28, 2026.<\/p>\n\n\n\n

Access<\/h2>\n\n\n\n

1. What is the official WhatsApp Business API?<\/h3>\n\n\n\n

It is Meta’s WhatsApp Business Platform, used today through the Cloud API: an HTTP API hosted by Meta that lets your system send and receive messages, with events delivered by webhook. It is the only route Meta authorizes for automating a business’s WhatsApp. See WhatsApp Cloud API: what it is, how it works and what it costs<\/a>.<\/p>\n\n\n\n

2. Are the WhatsApp Business API and the WhatsApp Business app the same thing?<\/h3>\n\n\n\n

No. The WhatsApp Business app is a free app run by hand on a phone, with no endpoint and no webhook. The API (WhatsApp Business Platform, Cloud API) is for systems: CRM integration, chatbots, notifications and multiple agents. The names are explained in WhatsApp Business API, Business Platform and Cloud API<\/a>.<\/p>\n\n\n\n

3. How do I get access to the WhatsApp Business API?<\/h3>\n\n\n\n

You need a Meta business portfolio, a number registered on the Cloud API, a Messaging account with a payment method, and an app with permission to use those assets. You can do it directly in Meta’s developer dashboard or through a provider’s Embedded Signup. Step by step in how to get WhatsApp Business API access<\/a>.<\/p>\n\n\n\n

4. Can I build my own WhatsApp API?<\/h3>\n\n\n\n

Yes, as long as it is a layer in your system on top of the official Cloud API: a Meta app, a system user token, a webhook and a registered number. Building your own channel by reverse engineering the app breaks the Terms of Service. Details in can I build my own WhatsApp API?<\/a>.<\/p>\n\n\n\n

5. Should I go directly to Meta or use a provider?<\/h3>\n\n\n\n

Directly, there is no access fee, but you maintain the app, tokens and webhook, and rely on Meta’s developer support channels. A provider charges for its layer and offers support, an inbox and, often, coexistence. Full comparison in directly from Meta or through a provider<\/a>.<\/p>\n\n\n\n

6. Can unofficial APIs (Baileys, WPPConnect) get my number banned?<\/h3>\n\n\n\n

Yes. These libraries emulate WhatsApp Web, and WhatsApp’s Terms of Service prohibit unauthorized automated access, so numbers can be banned without warning. See official vs. unofficial WhatsApp API<\/a>.<\/p>\n\n\n\n

Pricing<\/h2>\n\n\n\n

7. Is the WhatsApp Business API free?<\/h3>\n\n\n\n

Access is free, messages are not. Meta charges per delivered message, based on category and the recipient’s country. There are exceptions, such as the monthly free tier for service messages and the free entry point window from ads. See is there a free WhatsApp API?<\/a>.<\/p>\n\n\n\n

8. How does Meta charge for messages?<\/h3>\n\n\n\n

Per delivered message, priced by category (marketing, utility, authentication, service or Meta Business Agent) and by the recipient’s country. Meta only changes prices on the first day of a quarter: January 1, April 1, July 1 or October 1. To estimate a send, see how much a WhatsApp campaign costs<\/a>.<\/p>\n\n\n\n

9. How much does a message to Brazil cost?<\/h3>\n\n\n\n

Since October 1, 2026, for recipients in Brazil: marketing costs R$ 0.3217 (Brazilian reais) and utility, authentication and service cost R$ 0.0350 per message. These are Meta’s list prices, before taxes and before any intermediary’s fee. Other markets are in WhatsApp API pricing by country<\/a>.<\/p>\n\n\n\n

10. Are service messages charged?<\/h3>\n\n\n\n

Since October 1, 2026, each business phone number gets a free tier of 1,000 delivered service messages per month; from the 1,001st on, they are charged. The free tier doesn’t roll over and doesn’t cover utility templates. Without a payment method, Meta stops delivering service messages once the free tier is used up.<\/p>\n\n\n\n

11. Are utility templates free inside the customer service window?<\/h3>\n\n\n\n

Not anymore. Since October 1, 2026, utility templates sent inside the customer service window are charged. They are still free inside a free entry point window. What changed is covered in utility messages in the customer service window<\/a>.<\/p>\n\n\n\n

12. What is the free entry point window?<\/h3>\n\n\n\n

It opens when a customer messages you from a click-to-WhatsApp ad (on Android or iOS) and you reply within the customer service window. It can stay open for up to 7 days, and during that time Meta doesn’t charge for marketing, utility, authentication or service messages. See how to measure those ads in tracking click-to-WhatsApp ads<\/a>.<\/p>\n\n\n\n

13. Does the price depend on the customer’s country?<\/h3>\n\n\n\n

Yes. The price is set by the recipient’s country code, not your company’s country. A marketing message to a number in Mexico has a different rate from one to Brazil. Rate tables are in WhatsApp API pricing by country<\/a>.<\/p>\n\n\n\n

Templates<\/h2>\n\n\n\n

14. What is a template?<\/h3>\n\n\n\n

A message format approved by Meta, required to start a conversation or to message a customer outside the 24-hour window. It has a category, a language, body text with variables and, optionally, a header, footer and buttons. Ready-made examples are in 60 WhatsApp template examples by industry<\/a>.<\/p>\n\n\n\n

15. What are the template categories?<\/h3>\n\n\n\n

Marketing, utility and authentication. Utility covers messages tied to a customer’s transaction or account; authentication covers verification codes; everything else is marketing. The category sets the price, and Meta can recategorize a template. See WhatsApp template categories<\/a>.<\/p>\n\n\n\n

16. How long does Meta take to approve a template?<\/h3>\n\n\n\n

Review is automatic and, according to the documentation, can take up to 24 hours. Edited templates are reviewed again. To avoid back-and-forth, see the common rejection reasons<\/a>.<\/p>\n\n\n\n

17. How many templates can I have?<\/h3>\n\n\n\n

Unverified portfolios can have up to 250 templates per Messaging account. Verified portfolios with an approved display name on at least one number can have up to 6,000. You can also create at most 100 templates per hour per account. Key terms are in the WhatsApp API glossary<\/a>.<\/p>\n\n\n\n

18. Can I use the API for debt collection?<\/h3>\n\n\n\n

Collecting third-party debt is prohibited by the WhatsApp Business Messaging Policy. A billing reminder about the customer’s own invoice, such as an upcoming payment, is a utility message. See WhatsApp billing reminders without getting blocked<\/a>.<\/p>\n\n\n\n

19. Will the Cloud API stop sending marketing messages?<\/h3>\n\n\n\n

Yes. Meta has announced that the Cloud API stops supporting marketing messages on October 13, 2027, and Messaging accounts created on or after April 13, 2027 won’t be able to send marketing through it. The path forward is the Marketing Messages API; utility, authentication and service stay on the Cloud API. See how to migrate your marketing sends<\/a>.<\/p>\n\n\n\n

Limits<\/h2>\n\n\n\n

20. What is the 24-hour window?<\/h3>\n\n\n\n

It is the period opened by every customer message. Inside it, you can reply with any message type (text, media, buttons). Outside it, only approved templates. Each new customer message restarts the clock. How pricing works inside the window is covered in utility messages in the customer service window<\/a>.<\/p>\n\n\n\n

21. What is the API’s messaging limit?<\/h3>\n\n\n\n

New business portfolios start at 250 unique recipients per 24 hours outside the customer service window. The next tiers are 2,000, 10,000, 100,000 and unlimited. The limit belongs to the portfolio and is shared by all its numbers. Planning around it is covered in Black Friday on WhatsApp<\/a>.<\/p>\n\n\n\n

22. How do I raise my messaging limit?<\/h3>\n\n\n\n

To reach 2,000, verify your business or send 2,000 delivered messages outside the window to unique numbers within 30 days, using high-quality templates. Beyond that, increases are automatic: keep quality high and use at least half your current limit over the last 7 days. See WhatsApp phone number quality rating<\/a>.<\/p>\n\n\n\n

23. How many messages per second can the API send?<\/h3>\n\n\n\n

Up to 80 messages per second per number by default, with capacity upgrades available. Numbers in coexistence with the app are fixed at 20 messages per second. Going over that pace returns error 130429; sending too fast to the same recipient returns 131056. See throughput and rate limits<\/a>.<\/p>\n\n\n\n

24. Why wasn’t my marketing template delivered?<\/h3>\n\n\n\n

A common cause is the per-user marketing limit: Meta caps how many marketing templates one person receives from businesses over a period, and the send fails with error 131049. Fixes in error 131049 and the marketing limit<\/a>.<\/p>\n\n\n\n

25. Can my number be blocked on the official API?<\/h3>\n\n\n\n

Using the API doesn’t get you blocked, but breaking policy does: reports, user blocks and messaging without consent hurt quality and can lead to restrictions. The Business Messaging Policy requires opt-in and honoring opt-out requests. See how to build a WhatsApp opt-in list<\/a>.<\/p>\n\n\n\n

Coexistence<\/h2>\n\n\n\n

26. What is coexistence?<\/h3>\n\n\n\n

Using the same number on the WhatsApp Business app and the Cloud API at the same time: your team stays on the phone while your system replies through the API. Meta documents onboarding through Embedded Signup, run by partners. See WhatsApp coexistence with a CRM<\/a>.<\/p>\n\n\n\n

27. What stops working with coexistence?<\/h3>\n\n\n\n

According to Meta, group chats are not synced, broadcast lists become read-only, disappearing and view-once messages are turned off in 1:1 chats, and linked devices are disconnected during onboarding. Details in what syncs and what doesn’t<\/a>.<\/p>\n\n\n\n

28. Can I use a number that is already on WhatsApp?<\/h3>\n\n\n\n

If the number is on the WhatsApp Business app, you can connect it through coexistence. If it is on regular WhatsApp, you must delete the account from the app before registering the number on the Cloud API. See using an existing WhatsApp number with the API<\/a>.<\/p>\n\n\n\n

Technical<\/h2>\n\n\n\n

29. How do I send a message through the API?<\/h3>\n\n\n\n

With a POST<\/code> to \/{phone_number_id}\/messages<\/code> on the Graph API, a token in the Authorization<\/code> header and a JSON body with messaging_product: \"whatsapp\"<\/code>, the recipient, the type and the content. Outside the window, the type must be template<\/code>. Examples in cURL, Node.js and Python are in sending WhatsApp messages via API<\/a>.<\/p>\n\n\n\n

30. How do I receive customer messages?<\/h3>\n\n\n\n

Through a webhook: you register an HTTPS URL, answer the verification challenge and subscribe to the account’s fields (such as messages<\/code>). Meta sends a JSON POST<\/code> for each incoming message and each status change. See message status via webhook<\/a>.<\/p>\n\n\n\n

31. How do I make sure a webhook came from Meta?<\/h3>\n\n\n\n

Validate the X-Hub-Signature-256<\/code> header, which carries an HMAC SHA-256 of the request body generated with your app secret. Compare it with the HMAC you compute over the raw body, before any parsing. Step by step with code in validating the webhook signature<\/a>.<\/p>\n\n\n\n

32. How do I get a token that doesn’t expire?<\/h3>\n\n\n\n

Create a system user in Business Settings, assign it the app and the WhatsApp account, and generate a token with the business_management<\/code>, whatsapp_business_messaging<\/code> and whatsapp_business_management<\/code> permissions. The dashboard’s temporary token expires quickly. See permanent access token with a system user<\/a>.<\/p>\n\n\n\n

33. How do I download a photo or audio the customer sent?<\/h3>\n\n\n\n

The webhook carries the media ID, not the file. You look up that ID on the Graph API to get the URL, then download the file with the same token in the header. Full flow in receiving and downloading media<\/a>.<\/p>\n\n\n\n

34. Can I run an AI chatbot on the API?<\/h3>\n\n\n\n

Yes. The webhook receives the message, your system calls the AI model and replies through the API inside the 24-hour window. Since July 2026 there is also a Meta Business Agent category, for replies generated by Meta’s own AI platform. A tutorial with code is in connecting ChatGPT to the official API<\/a>.<\/p>\n\n\n\n

Account<\/h2>\n\n\n\n

35. Do I need to verify my business on Meta?<\/h3>\n\n\n\n

Not to get started, but verification changes what you can do: it is one way to move from 250 to 2,000 recipients and it unlocks more numbers and templates. See how to get WhatsApp Business API access<\/a>.<\/p>\n\n\n\n

36. How many numbers can I register?<\/h3>\n\n\n\n

New portfolios can register two numbers. The cap goes to 20 once the business is verified or reaches the 2,000 messaging limit. Each number needs a country and area code and must receive an SMS or call. See registering a number on the Cloud API<\/a>.<\/p>\n\n\n\n

37. What changed with the WABA in 2026?<\/h3>\n\n\n\n

Since September 23, 2026, the former WABA is split into a WhatsApp account, which holds the number, and a Messaging account, which holds templates, billing and webhooks. That changes how partners access the account and how you switch providers. See WhatsApp account vs. Messaging account<\/a>.<\/p>\n\n\n\n

38. How do I switch providers without losing my number?<\/h3>\n\n\n\n

With the new structure, switching providers means sharing your WhatsApp account with the new partner, who then operates it with their own Messaging account. The number stays yours throughout. See switching WhatsApp API providers<\/a>.<\/p>\n\n\n\n

39. How does the display name work?<\/h3>\n\n\n\n

It’s the name customers see. You provide it when registering the number, and Meta reviews it, with statuses such as pending, approved or declined. Rules in WhatsApp display name on the API<\/a>.<\/p>\n\n\n\n

40. Where do I get support from Meta?<\/h3>\n\n\n\n

All developers can use Meta developer support, the community forum and the bug report form. Direct Support, with tickets, is described as a channel for enterprise developers such as partners; partners’ customers should contact their partner. See Meta support for WhatsApp Business<\/a>.<\/p>\n\n\n\n

How Vectalk helps<\/h2>\n\n\n\n

Vectalk is a proxy for Meta’s official Cloud API: your application sends the same Meta payload to https:\/\/apis.vectalk.com.br\/api\/messages<\/code>, and Vectalk forwards it. You pay Vectalk, and Vectalk pays Meta. Webhooks follow the format in Meta’s documentation, and the number can run in coexistence with the WhatsApp Business app. Start with the quickstart<\/a> or sign up at apps.vectalk.com.br\/register<\/a>. Account and billing questions go to the Help Center<\/a>.<\/p>\n\n\n\n
