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:

1. Call this endpoint to request a verification code
2. User receives code via SMS or voice call
3. Use the verify_code endpoint to complete verification
4. 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
