WhatsApp Business API

WhatsApp Business API Connect your business to WhatsApp through the official WhatsApp Business API. This channel is the recommended choice for businesses that need reliable, high-volume WhatsApp messaging with pre-approved message templates and delivery tracking. No separate Twilio account needed. Twilio is the phone and messaging service that delivers your WhatsApp messages behind the scenes. The platform creates a managed Twilio account for you under the hood, so you don't need to sign up for Twilio yourself or wire it to Meta manually. Buying a number or connecting an existing one happens entirely inside the app. If you specifically need to bring your own Twilio account (e.g. you already have warmed-up numbers and approved templates there), open the Twilio Account card on the Channels page and switch to your own account, then attach your existing sender — both steps are in SMS Provider (Bring Your Own Twilio) . Most users should stick with the managed setup. Prerequisites Before you begin, make sure you have the following: A Meta Business account (business.facebook.com) — business verification is optional : unverified businesses can activate a number, get templates approved, and send broadcasts, starting at the 250 unique contacts per 24 hours limit (see Messaging Limits below) An account with sufficient credits A phone number that is not already registered with WhatsApp (personal or Business app), and that is not already a Twilio number from another account Add your busin
