Request a verification code for a WhatsApp Business phone number via SMS or voice call.
This is the first step in the phone number verification process.
Use Cases:
- Initial verification of newly added phone numbers
- Re-verification when phone number status requires it
- Switching between SMS and voice verification methods
Rate Limiting:
Standard Graph API rate limits apply. Additional rate limiting may be enforced
for verification code requests to prevent abuse.
Security:
Verification codes are sent only to the registered phone number and expire
after a short time period. Multiple failed attempts may result in temporary blocking.
