WhatsApp Business API — distinct from the regular WhatsApp Business app — enables businesses to send messages at scale, automate transactional notifications, run marketing broadcast campaigns and build multi-step conversation flows without manual intervention. Unlike SMS or email, WhatsApp messages are read within minutes. For Indian businesses, WhatsApp automation solves the most common growth problems: following up on leads who enquired but did not convert, notifying customers about order status, collecting payment from overdue invoices, re-engaging dormant customers and running time-sensitive promotional campaigns. At Chulbul Design, we set up WhatsApp Business API on approved business accounts, build automation workflows, design template messages that pass Meta's approval process and integrate everything with your existing CRM, order management or website.
WhatsApp Broadcast Campaigns — 98% Open Rate Marketing
WhatsApp broadcast campaigns via the Business API send template messages to your opted-in customer database — promotional offers, festival campaigns, new product launches, webinar invites or reactivation offers. Unlike the WhatsApp Business app (which limits you to 256 contacts per broadcast), the API has no upper limit. Messages arrive as individual chats to each recipient, not as a group, so they feel personal. For Indian businesses, we build festival campaign calendars (Diwali, Navratri, New Year), product launch sequences with image/video attachments, drip nurture sequences for leads who enquired 7–30 days ago and win-back campaigns for customers who have not purchased in 90+ days.
<br><em>A Delhi clothing brand: ₹15,000 WhatsApp campaign in Diwali season generated ₹4.2 lakh in orders within 48 hours — 28x ROI on a single broadcast.</em>
- Unlimited broadcast to opted-in customer database
- Festival campaign calendar — Diwali, New Year, Holi
- Image, video and document attachments supported

Transactional Automation — Orders, Payments and Reminders
The most immediate ROI from WhatsApp automation comes from transactional notifications that replace manual follow-up. Order confirmation, shipping dispatch with tracking link, delivery confirmation, payment receipt, payment reminder (3 days before due, 1 day before due, day of due, 2 days overdue), appointment reminder 24 hours before, service ticket update and feedback request after service completion — all sent automatically based on triggers from your order management system, payment gateway or CRM. For businesses losing 15–20% of invoices to late or no payment, an automated payment reminder sequence via WhatsApp recovers a significant portion without any manual effort from your team.
- Order confirmation and dispatch tracking messages
- Payment reminder sequences — before and after due date
- Appointment reminder and confirmation automation
- Post-service feedback collection via WhatsApp
- Integrated with Razorpay, Shiprocket, WooCommerce, Zoho
Lead Nurture Drip Sequences — Convert Enquiries Automatically
Most Indian businesses collect leads but follow up inconsistently — the sales team calls once, the lead does not pick up, and the conversation dies. A WhatsApp drip nurture sequence keeps the conversation alive automatically: Day 1 — thank you for enquiry + specific information about the service they asked about; Day 3 — a case study or testimonial from a similar customer; Day 7 — FAQ addressing common objections; Day 14 — a limited-time offer or consultation invite; Day 30 — re-engagement with new offer. Each step is triggered automatically when a new lead enters your CRM from your website form, chatbot, Google Ads or social media. High-value leads that respond to any message are flagged for immediate human follow-up.
- Multi-step drip sequences triggered by lead source
- Personalised messages based on service category interest
- Response detection — hot leads routed to sales instantly
- 30/60/90 day re-engagement for cold leads
- Opt-out compliance — stop message on request
