Frequently asked questions

What is the WhatsApp Business API?

It is the official way for medium and large businesses to send WhatsApp messages at scale, integrate with their systems and let multiple agents reply from one number.

How is WhatsApp Business API pricing calculated?

Pricing combines Meta's per-message charges, which depend on the message category and country, and the TalkNest platform fee. See our pricing page or contact sales for current rates.

Can I get the green tick on WhatsApp?

The verified badge is granted by Meta. We help you prepare and submit the request; approval depends on Meta's criteria.

Do I need a new phone number?

You can use a new or existing number, as long as it is not currently registered on the regular WhatsApp or WhatsApp Business app.
