# Request the WhatsApp verification code for a number

`POST /v1/messaging/phone-numbers/{id}/whatsapp/request-code`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/messaging/phone-numbers/{id}/whatsapp/request-code`
- Auth: HTTP bearer

Starts (or restarts) WhatsApp verification of a Zernio-hosted number:
adds it to Meta's pre-verified pool when needed and asks Meta to send
the verification code, which Zernio captures on the number itself.
Used to connect WhatsApp on a number bought for calls or SMS.
`/v1/whatsapp/phone-numbers/{id}/request-code` is a deprecated alias
with the same contract.

When Meta refuses the number for WhatsApp (Meta error 136021):
a number that is already live (`active` or `suspended`) is left
untouched and keeps working for calls and SMS, and the call answers
409 `number_not_whatsapp_eligible`; buy a new number with WhatsApp
enabled instead. A number that was never live (still verifying) is
replaced at no extra cost with a WhatsApp-eligible number on the same
record, answered as 200 with `replaced: true`.


**Billing:** Request; paid actions are priced in credits (see GET /v1/messaging/prices) · **Rate limit:** 60/min
