Direct Answer: Setting Up the WhatsApp Business API

To set up the WhatsApp Business API, you must register a Meta Developer Account, create a Meta Business Manager Portfolio, add a verified phone number dedicated to the API, and configure billing. The process takes between 1 to 3 business days, depending on Meta’s verification speed, and unlocks features like automated template messaging and multi-agent integrations.

Core Steps for Setup

  1. Create a Meta Developer Account: Go to developers.facebook.com and register as a developer. Create a new App and choose the 'Business' type.
  2. Add WhatsApp Product: Within the Meta Developer App dashboard, click 'Set Up' under the WhatsApp product card.
  3. Link a Phone Number: Input a clean phone number that does not have an active WhatsApp consumer or business app account. Verify the number via SMS or voice call.
  4. Complete Meta Business Verification: Provide official registration papers for your B2B company in Meta Business Suite to unlock high sending limits (100k+ messages per day).

Frequently Asked Questions

Can I use my existing WhatsApp number for the API?

No. The phone number must be deleted from the consumer or business app first before it can be registered on the API platform.
