FAQ
Can we use an existing WhatsApp number for API integration?
No. The number must not be linked to any existing WhatsApp or WhatsApp Business App. If it is, you must delete that account first.
Is it mandatory to have a business website?
Yes. An active website with business details, a privacy policy, and terms and conditions is required for verification.
Why is two-factor authentication (2FA) required?
Meta mandates 2FA for security purposes. Without enabling it, you won’t be able to access or use the API.
Can we create multiple apps under one business account?
Yes. You can create multiple apps, but each integration should be properly configured.
