WhatsApp is one of the most effective ways to reach customers in India. Businesses have two official options: the free WhatsApp Business App and the WhatsApp Business Platform, often called the API. They serve different needs.

WhatsApp Business App

  • Free app for one phone (plus linked devices).
  • Business profile, catalogue, quick replies and labels.
  • Broadcast lists that reach only contacts who saved your number.
  • Best for small businesses handling chats manually.

WhatsApp Business Platform (API)

  • Connects WhatsApp to your software, website or store.
  • Automated messages such as order, payment and appointment updates.
  • Approved message templates for campaigns to opted-in customers.
  • Shared team inbox, chatbots and reports.
  • Charged per conversation by Meta, plus the software you use.

Which should you choose?

If you reply to a few dozen chats a day yourself, the Business App is enough. If you need automation, several staff answering chats, campaigns to large opted-in lists, or integration with your store or billing software, the Business Platform is the right tool.

Stay compliant

  • Message only customers who have opted in.
  • Use approved templates for marketing and updates.
  • Make it easy to opt out.
  • Avoid unofficial bulk-sending tools, which risk your number being banned.

What you can automate with the API

  • Order confirmations, dispatch and delivery updates.
  • Payment links and payment reminders.
  • Appointment confirmations and reminders.
  • Welcome messages and replies to common questions.
  • Collecting leads from ads and website buttons.

Planning a WhatsApp campaign

  1. Build an opted-in contact list, for example from checkout or website forms.
  2. Segment contacts by interest or purchase history.
  3. Write a short, useful message with one clear action.
  4. Get the template approved and send at a sensible time.
  5. Track delivered, read and reply rates and refine the next campaign.

Keeping conversations personal

WhatsApp feels personal, so treat it that way. Use the customer's name, send only relevant offers, and make sure a real person can take over from automation when needed. Fewer, better messages keep customers engaged and protect your number's quality rating.

Frequently asked questions
