POST ///request_code

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.
