To set up the WhatsApp Business API in, you need to navigate a specific hierachy within the Meta ecosystem. Think of it as a three-layer pyramid: your Business Portfolio is the foundation, the WhatsApp Business Account (WABA) is the engine, and your Phone Number is the driver.
The Meta Business Portfolio (formerly Business Manager)
is the central hub where you manage your business assets.
Complete Business Info:
The WABA is the actual messaging account that lives inside your Meta Business Portfolio.
The "Clean" Number Rule
Display Name Rules
Meta uses a tiered verification system to confirm the identity of your business.
Business Verification
Benefits
Verification allows you to scale messaging limits and apply for the WhatsApp Green Tick.
Two-Factor Authentication
Mandatory for all API accounts. You must create a 6-digit PIN in WhatsApp Manager.
| Step | Action | Tools Needed |
|---|---|---|
| 1 | Create Meta Business Portfolio | Personal Facebook Account + Work Email |
| 2 | Add Website & Legal Address | Official Domain + Utility Bill |
| 3 | Create WABA Account | Meta Business Suite / BSP |
| 4 | Verify Phone Number | 6-Digit SMS or Voice Code |

Personal IDs such as NIN, Voter's Card, or Passport verify
the admin but do not verify the business entity.
For Nigerian phone numbers, the Phone Call verification option is often more reliable than SMS.
