How to Set Up the WhatsApp Business API, Step by Step

Getting on the WhatsApp Business Platform takes a few steps and some paperwork, but no code if you use a platform. Here is the order that avoids delays.

In Short

Create or use a Meta business portfolio, choose a provider, register a phone number not used on the WhatsApp app, set an approved display name, verify your business, submit templates and start messaging.

Before You Start

• Access to your company's Meta business portfolio (Business Manager) with admin rights.
• A phone number that can receive a code by SMS or call and isn't active on WhatsApp — or one you're ready to move.
• Your legal business name, address and website matching your documents.

The Steps

1. Choose how to connect. Meta Direct (Cloud API), or a provider such as Infobip or Twilio. See the comparison.
2. Run embedded signup. Log in with Facebook, pick the business portfolio and create a WhatsApp Business Account.
3. Add the number and display name. The display name should match your brand and is reviewed by Meta.
4. Verify your business. Upload documents in the business portfolio to raise messaging limits.
5. Create templates. Submit marketing, utility and authentication templates for approval.
6. Connect your inbox. In Arino One, connect the account and start receiving messages.

Common Delays

• Display names that don't match the business or website.
• Documents with a different legal name than the portfolio.
• Templates rejected for formatting — see why templates get rejected.
