How do I start with the WhatsApp Business API?

Updated 25 October 2026 · 1 min read

Quick answer

You can start with the official WhatsApp Business API through Bulk SMS India. You need a business, a phone number for WhatsApp and a Facebook (Meta) Business account.

Steps

  1. Choose a number that is not active on the normal WhatsApp app, or move it to the API.
  2. Connect your Meta Business account with our team's help.
  3. Set your display name and profile. Business verification can help you get a verified name.
  4. Create message templates for anything you send outside a 24-hour chat. Meta approves them, often quickly.
  5. Start campaigns, chatbots and the team inbox.

Costs

Meta charges per message by category (marketing, utility, authentication), plus the platform fee. See WhatsApp Business API pricing and WhatsApp messaging.

WhatsApp messages do not need DLT, so you can go live while your SMS DLT registration is in progress.

More questions

Can I use my existing WhatsApp number?

Yes, but a number on the API cannot be used in the normal WhatsApp app at the same time.

Do I need a green tick to start?

No. You can start without it. Business verification helps build trust and may lead to a verified name.

How are WhatsApp messages charged?

Meta charges per message by category, marketing, utility or authentication, plus the platform fee.
