Request a verification code for a pre-verified phone number via SMS or voice call.
This is part of the WhatsApp Business Account onboarding process where pre-approved
phone numbers must be verified before they can be used for messaging.
Process Flow:
- Call this endpoint to request a verification code
- User receives code via SMS or voice call
- Use the verify_code endpoint to complete verification
- Phone number becomes active for messaging
Rate Limiting:
- Limited number of code requests per phone number per time period
- Exponential backoff recommended for retry attempts
- Voice calls may have additional restrictions
Language Support:
Verification messages are sent in the specified language when available.
Falls back to English (en_US) if the requested language is not supported.
Security Considerations:
- Codes expire after a short time period
- Limited number of verification attempts allowed
- Phone number must be pre-verified and owned by requesting business
