How each one connects
The official WhatsApp Business Platform (Cloud API) is run by Meta. Your number is registered to the platform, messages go through Meta's servers, and the number stops working in the WhatsApp app.
An unofficial API links your number as a device, the same way WhatsApp Web does. The number stays on your phone, and the API sends and receives as that linked device.

Choose official when
- You message large audiences who have not contacted you.
- You run Click-to-WhatsApp ads.
- A ban would be unacceptable, for example banks and large brands.
Choose unofficial when
- You mostly talk to customers who already know you.
- Per-message costs would exceed the value of the messages.
- You need groups, statuses or the number on your own phone.
- You want to start today without verification.
Using both
Many businesses run an official number for marketing and an unofficial one for service. AgaKural works alongside any official provider. Compare providers in the best WhatsApp API in India.
Frequently asked questions
Is using an unofficial WhatsApp API illegal?
It is not a crime, but it is against WhatsApp's terms of service, which is why numbers can be banned. AgaKural is independent and not affiliated with WhatsApp or Meta.
Can I move from unofficial to official later?
Yes. Unlink the number, then register it on the official platform through a partner.
Which is faster to set up?
Unofficial: you scan a QR code and send in minutes. Official setup needs Meta Business verification for higher limits.
