How to set up a WhatsApp chatbot in 2026: the Meta steps, choosing a vendor, WhatsApp's AI policy, and a checklist you can follow.
Setting up a WhatsApp chatbot involves a few steps on Meta's side and a few in your chatbot tool. How long it takes depends mostly on how quickly Meta verifies your business and whether your vendor offers self-service setup or runs an implementation project. This guide explains how to set up a WhatsApp chatbot step by step, including the WhatsApp Business Platform parts that often catch teams out.
A quick disclosure: we build SimplyBoost, so we use it for the step-by-step example. The Meta steps are the same whichever vendor you choose.
Before you start: three decisions
- Choose the number. A personal WhatsApp account can't be automated, so you need the WhatsApp Business Platform (the API). Decide whether to use a new number or move an existing business number over.
- Choose your chatbot vendor. The vendor connects to the WhatsApp Business Platform for you and runs the AI agent. Some tools only do WhatsApp, while others, SimplyBoost included, run one agent across WhatsApp, your website and Instagram.
- Decide what the bot is for. Since 15 January 2026, the WhatsApp Business Solution terms don't allow general-purpose AI assistants where the AI itself is the main product. Bots that help customers with a business's own services, like support, order questions, bookings and lead capture, are fine. Write down what your agent should and shouldn't handle before you go live.
How to set up a WhatsApp chatbot with SimplyBoost
- Sign up at get.simplyboost.io. The 7-day free trial includes 100 AI replies.
- Connect WhatsApp. SimplyBoost uses Meta's official embedded signup, so you log in with Facebook, choose or create your Meta business account and verify your phone number in a Meta window. There are no API credentials to copy across.
- Add your knowledge. A website URL is enough for many businesses. You can crawl up to 50 sub-pages, add a sitemap, or upload PDFs, Word files and FAQs. Everything is processed in the background, and the agent answers only from what you add.
- Set the basics and test. Choose the tone, reply length and reply language, check the handover rules, then message your business number from your own phone with the questions your customers usually ask.
- Go live. Share your WhatsApp number, add a click-to-chat link to your website, or put a QR code on printed materials.
A few things to know about how the agent behaves on WhatsApp. It replies to messages customers send, within 24 hours of their last message, which is WhatsApp's customer service window. If someone sends a voice note, photo or sticker, it politely asks them to type their question. It doesn't send broadcasts, campaigns or template messages. When a customer asks for a person, or a question needs your team, it hands over and alerts you by email and in the dashboard, and in Slack if you connect it.
Setting up a WhatsApp chatbot with other vendors
Timelines vary with the vendor's approach. Tools with self-service onboarding usually let you connect WhatsApp and start testing on your own. Enterprise-focused platforms often begin with a sales call, then a kickoff and an implementation team, which can take weeks.
If timing matters, ask each vendor directly: "How long from sign-up to the first real customer conversation on WhatsApp, and what do I need to do myself?" The answer tells you a lot about how the product works.
WhatsApp Business Platform steps that catch teams out
Meta has its own checks, separate from your chatbot tool. These three are worth understanding before you start.
1. Business verification
Meta asks businesses to verify themselves in Meta Business Manager, usually by uploading registration documents (for a Dutch business, your KVK extract). Verification unlocks higher messaging limits and other features, and it can take a few days, so start early.
2. Display name approval
Meta reviews the display name shown on your WhatsApp business profile. A name that clearly matches your business is the safest choice. Generic names like "Customer Support" are more likely to be rejected.
3. Template messages
When a business messages someone first, for example with a notification or reminder, it has to use a template Meta has approved. When the customer messages you, you can reply freely within 24 hours of their last message without a template. SimplyBoost's agent works in that second situation: it answers the messages customers send.
WhatsApp's 2026 AI policy: what's allowed
Since 15 January 2026, the WhatsApp Business Solution terms don't allow providers of general-purpose AI assistants to use the platform when the AI itself is the main thing on offer. Business assistants that help customers with a company's own products and services are still allowed, such as customer support, order questions, bookings and lead capture.
A support agent that answers questions about your business from your own content sits clearly on the allowed side. It's still good practice to tell people they're talking to an AI, for example in your welcome message, and in the EU the AI Act's chatbot transparency rules have applied since 2 August 2026.

Frequently asked questions
Do I need a separate phone number for a WhatsApp chatbot?
It's a good idea. Most businesses use a dedicated number for the WhatsApp Business Platform, either a new one or a separate business mobile number, so personal and business conversations stay apart.
How long does WhatsApp Business Platform approval take?
It varies. Business verification in Meta Business Manager can take a few days, longer if Meta asks for more documents, and display name review is usually quicker. Once that's done, connecting the number through a vendor's signup flow is quick. Leave yourself some room before a planned launch date.
Can I use WhatsApp Business app instead of WhatsApp Business Platform?
The WhatsApp Business app is made for people replying by hand on a phone, and it doesn't support connecting an AI chatbot the way the API does. For a chatbot you need the WhatsApp Business Platform. The app is fine for very small businesses answering messages themselves.
What does WhatsApp Business Platform cost?
Since 1 July 2025 Meta charges per delivered template message, with rates that depend on country and category. Replies to customers within the 24-hour customer service window are free, and so are utility templates sent inside that window. Your chatbot vendor's fees come on top. Compare chatbot pricing models
Which AI chatbot is best for WhatsApp specifically?
For most businesses, SimplyBoost (our product). It connects through Meta's official WhatsApp Business Platform with embedded signup, answers only from your own content in each customer's language, and runs the same agent on your website and Instagram. Plans are a flat €39, €89 or €169 a month for 500, 2,000 or 6,000 AI replies, with no fees per seat, per conversation or per channel, and handover into Zendesk, Freshdesk, Gorgias or Slack on every plan. If you mainly send broadcasts and campaigns, a WhatsApp-first marketing tool may suit that part better. See the SimplyBoost WhatsApp chatbot
