The four things people confuse
Phone number verification
The only step actually required to start. You verify ownership of your number with
an OTP.
So the honest answer: verify your phone number, and you can message real customers
today — no documents, no waiting on approvals.
The number you have to respect
| Stage | Daily reach |
|---|---|
| Before business verification | 250 unique customers / 24 hours |
| After business verification | 1,000 unique customers / 24 hours |
| Then | Scales up automatically with volume + good quality rating |
Cloud API vs coexistence
- Cloud API — your number is not on any WhatsApp app; ChatSyncs/Meta handles it entirely. Here a display name must be approved.
- Coexistence — you keep using the WhatsApp Business app on the phone and the API; the app’s existing display name is used, so no separate approval.
Three mistakes that get beginners stuck
- “Number already registered to WhatsApp” — delete WhatsApp from that number first, wait, then register it on the API.
- Payment fails / templates won’t send — use a Visa or Mastercard with international transactions on, and add your Tax ID in Business Info billing (templates stay blocked until you do).
- Webhook not working — you must both return the
hub.challengeresponse and subscribe to the messaging event. They’re two separate steps people skip.
