Use Connect with Meta to link a WhatsApp Business account without copying credentials manually. On Add number, select WhatsApp Cloud (Cloud API only) or Coexistence with WhatsApp Business app (the Business app and WhatsApp Web stay on the number), then Continue. Complete Meta’s sign-in, choose the business account and number, and finish phone verification in the popup. Manual credential entry remains available on the Cloud path when one-click connection is not available for your workspace. Coexistence requires Connect with Meta. Existing Cloud senders cannot be converted in place.

Marketplace numbers + OTP

While a voice-delivered OTP capture session is open — up to 20 minutes, or until you finish or cancel it — inbound calls to that number are answered by a silent listener instead of your assigned assistant. Normal routing resumes automatically the moment the session ends.The code Meta reads out is shown live on this screen only. No assistant call is created and nothing is written to call history — the carrier delivers the code directly. The code is discarded when the session ends, so restart verification to get a new one if you miss it.
Buying a number in Settings → Numbers never auto-enables WhatsApp.
Marketplace-number verification is completed interactively in the dashboard. Other WhatsApp resources can be managed through the public API and MCP as described in WhatsApp (Text + Voice).
