Everything needed to get the WhatsApp Business API (Business Platform): requirements, the phone number question, business verification and a setup checklist.

The short answer
To get the WhatsApp Business API you need a Meta Business portfolio (Business Manager), a phone number that can receive a code and isn't tied up on another WhatsApp account, a display name that matches your business, and a provider (or Meta's Cloud API directly). Sign up through the provider's embedded Meta flow, verify the number, and you can start answering the same day; business verification raises your sending limits later.
“WhatsApp Business API” is what most people still call the WhatsApp Business Platform. There's no application form to wait on for months anymore — most businesses are connected in under an hour. What slows people down is not knowing the requirements in advance.
The requirements
| Requirement | What it means |
|---|---|
| Meta Business portfolio | Your business in Meta Business Manager. Create one free if you don't have it. |
| Phone number | Can receive an SMS or call for the code. If it's on the WhatsApp app now, it usually must be moved or freed first. |
| Display name | Your real brand name, consistent with your website and signage. Meta reviews it. |
| Website or business presence | Helps verification and the display-name review. |
| A provider (or Cloud API) | Software that connects to Meta's API and gives you an inbox, bots and templates. |
The phone number question
A number can be registered on the API only if it's not active on another WhatsApp account. If your business number runs on the WhatsApp Business app today, the classic route is to delete that WhatsApp account and register the number on the platform (chat history doesn't move). Meta has been introducing ways to use one number on both the app and the platform, so ask your provider whether that's available for your number before you delete anything.
Step-by-step setup
- 1Choose a provider and start its WhatsApp connection — it opens Meta's sign-up window.
- 2Log in with Facebook, pick (or create) your Meta Business portfolio.
- 3Create the WhatsApp Business account and enter the display name.
- 4Add the phone number and confirm it with the code.
- 5Send yourself a test message and reply from the provider's inbox.
- 6Start business verification in Business Manager to raise your messaging limits.
- 7Create your first templates — a reminder and an order update.

Connect WhatsApp to FlowistaCommon mistakes
- Using a number you can't receive codes on (an old SIM, a landline without call forwarding).
- A display name that doesn't match the business — it gets rejected.
- Buying contact lists and messaging them — the fastest way to a restricted number.
- Skipping business verification, then hitting the low starting limit on the first campaign.
Frequently asked questions
Is the WhatsApp Business API free to get?
Connecting is free on Meta's side. You pay for template messages you send first and for your provider's software.
How long does it take to get the WhatsApp API?
Connecting usually takes under an hour through a provider. Business verification can take a few days and raises your sending limits.
Can I use the WhatsApp Business app and API on the same number?
Traditionally no. Meta has been introducing options to use one number on both; ask your provider what's available for your number.
Do I need a website to get the WhatsApp API?
It's strongly recommended: Meta uses your web presence when reviewing your business and display name.
