Creating a WhatsApp Business API account step by step: what you need first, the embedded signup, and the first message
The actual steps to create a WhatsApp Business API account: a Facebook Business Manager, the number (new, or moved in coexistence mode), embedded signup from the dashboard, verification, the first template approval, and raising the sending limit through business verification — and the five mistakes that stall signup most.
The short answer
Three things before you start: a Facebook Business Manager in your business's name, a phone number that can take a verification call or SMS (if it is on the WhatsApp app choose coexistence mode so it stays there), and an email plus a business document if you want to raise the sending limit through verification. Then from the dashboard: "connect a number" opens Meta's embedded signup inside the page: log in with Facebook, pick or create the business account, enter the number and verify, and the number appears in the dashboard ready within minutes. No interview, no manual approval wait; the only approval that waits is message templates.

Three things before you start
| Thing | Why | If you do not have it |
|---|---|---|
| A Facebook Business Manager in your business's name | The WhatsApp Business API lives under it | Created free in minutes at business.facebook.com |
| A phone number that can take a verification call or SMS | Meta verifies it is yours | A landline works with call verification; a number on the app joins in coexistence mode |
| A business document (optional at first) | To verify the business and raise the sending limit | Start with 250 and verify later |
Signup step by step
- From the dashboard: connect a WhatsApp number
WhatsApp tools → numbers → connect a number. Meta's embedded signup opens inside the page itself — no copying tokens, no developer console.
- Log in with Facebook and pick the business account
With the account of whoever owns the Business Manager. Pick the existing account or create one in the same step, then the display name customers see (your business name as it is).
- Enter the number and verify
New: a code by SMS or call. On the app: choose "my number runs on WhatsApp Business" and it moves in coexistence mode, staying on your phone.
- The number in the dashboard — ready
It appears with its status and quality rating, and its sending limit once Meta reports it. Bind an AI agent and your files to it, and it answers whoever messages you from the first minute. Auto-reply.
- Approve the first template and verify the business
The template for what you start (confirmation, reminder) — minutes to two days. Verification from the Business Manager with an official document raises the limit from 250 to 2,000, then it rises on its own to 10,000, 100,000 and unlimited while quality stays high and you use half your limit within seven days. Template approval.
A Business Manager in a person's name, not the business — verification stalls later. A number on regular WhatsApp (not Business) — move it to the Business app first or use another number. A display name with someone else's brand — rejected. Logging in with an employee's account that does not own the Business Manager — no accounts show. Waiting for an "approval" that never comes — there is no manual account approval at all; what gets approved is templates.
Frequently asked questions
Do I need a registered company?
To sign up and send: no — a Facebook Business Manager in your business's name is enough, and you start with a limit of 250 unique recipients in any 24 hours outside the customer-service window. To raise it to 2,000: verify the business at Meta with an official document (commercial register or equivalent) and a matching name, or deliver 2,000 high-quality messages within 30 days without verification. The limits.
My number runs on the WhatsApp Business app — do I lose it?
No. Choose coexistence mode at signup: the number joins the official API and stays on the app with its chats, and contacts and recent conversations sync on the first day. The old way (deleting the number from the app, then registering) is no longer needed. App or API.
How long does signup take?
Minutes if the three things are ready (the business account, a number that can receive verification, a Facebook login by whoever owns the account). What takes time is the first template's approval (minutes to two days) and business verification (days).
Is there a signup fee at Meta?
No. You pay Meta for the template messages you start, on your own account with no markup from us. Your replies inside the 24-hour window are free today — and from 1 October 2026 each phone number gets 1,000 free a month, with the rest charged at the customer's market utility rate. The platform subscription is separate. Pricing.
Can I connect through Meta directly without a platform?
Yes, and then you own the replies, templates, inbox, team and bot yourself. The platform connects the same number through the same Meta signup, and adds what comes after. What the Cloud API is.
