Before You Start: Prerequisites
Setting up WhatsApp Business API requires specific things in place before you begin. Missing any of these causes delays.
**1. A Registered Business** โ Meta requires a legitimate business entity. You need either a GST registration, company incorporation certificate, or business registration document. Sole proprietorships work, but you need documentation โ Udyam/MSME certificate, Shop and Establishment license, or FSSAI license for food businesses.
**2. A Meta Business Manager Account** โ Create at business.facebook.com if you don't have one. You'll need a Facebook page for your business (even if you don't actively use Facebook). The Business Manager manages your WhatsApp API access.
**3. A Fresh Phone Number** โ The phone number you use for WhatsApp Business API cannot already be registered on WhatsApp or WhatsApp Business app. Get a new SIM or virtual number, or migrate your existing WhatsApp Business number (irreversible โ deletes app setup). Don't migrate your personal WhatsApp number.
**4. A Business Solution Provider (BSP)** โ Small and mid-size businesses access the API through a BSP who provides infrastructure, interface, and tools. AutoChat is a BSP โ we handle the technical layer.
Step-by-Step Setup
Step 1: Choose Your BSP and Sign Up
Compare BSPs on pricing model (per-conversation vs per-message vs monthly flat), features (chatbot builder, team inbox, CRM, analytics), support quality, and integrations. With AutoChat, sign-up takes 10 minutes.
Step 2: Connect Meta Business Manager
Your BSP guides you through connecting your Meta Business Manager account โ logging in, granting permissions, and linking your Facebook Business Page. This takes 15-20 minutes if your Meta Business Manager is already set up.
Step 3: Verify Your Business with Meta
Submit your business name (must match registration documents), address, phone number, website (strongly recommended), and official documents (GST certificate, incorporation certificate, etc.).
**Timeline:** 3-7 business days typically. Some businesses verify in 24 hours; others take 2 weeks. A well-established Facebook page and website speed this up.
**Common rejection reasons:** Name mismatch with documents, website domain doesn't match business name, blurry or expired documents, incorrect business category on Meta.
Step 4: Register Your Phone Number
After business verification, register your API phone number. You'll receive an OTP via SMS or voice call. After registration, the number works only through the API โ no longer usable in the WhatsApp or WhatsApp Business app.
Step 5: Set Up Your Business Profile
Configure your display name (subject to Meta approval), profile photo (minimum 640x640px), about text (139 characters max), business category, address and hours (optional but recommended), and website and email.
Step 6: Create Message Templates
WhatsApp requires pre-approved templates for any business-initiated message. Three categories:
- **Utility**: Order updates, appointment confirmations, payment receipts - **Marketing**: Promotions, offers, newsletters, product launches - **Authentication**: OTP and verification codes
**Template structure:** Header (optional text/image/video), body (your message with variables like {{1}} for personalization), footer (optional, often used for opt-out instructions), and buttons (call-to-action or quick reply).
**Example submission:** Category: Utility | Name: order_confirmation | Body: "Hi {{1}}, your order #{{2}} has been confirmed! Total: โน{{3}}. Expected delivery: {{4}}. Track your order here: {{5}}"
Approval takes 1-24 hours. Marketing templates take longer than utility. Start with 5-10 essential templates and add more as needed.
Step 7: Set Up Your Team Inbox
Add team members who will respond to customer messages. Configure routing rules (assign by topic, round-robin, or manually). Set business hours and auto-replies for off-hours. Configure notifications so agents don't miss messages.
Step 8: Build Your First Chatbot Flow
Even a simple chatbot saves significant time. Start with a welcome message, a menu of options (product info, support, track order), auto-responses for your top 5 FAQs, and handoff to a human agent when the chatbot can't help. AutoChat's visual flow builder makes this drag-and-drop with no coding.
Step 9: Test Everything
Before going live: send test messages from a personal number, verify chatbot flows work correctly, test template messages, check team inbox routing, verify auto-replies trigger correctly during and outside business hours, and test on both Android and iOS.
Step 10: Go Live and Promote
Add your WhatsApp number to your website (click-to-chat button), Google My Business listing, social media profiles, business cards, email signatures, and in-store signage with QR code.
Cost Breakdown for Indian Businesses
**BSP platform costs:** Vary by provider. Contact AutoChat for current pricing based on your volume and features.
**Meta conversation charges (2026):** - Utility conversations (order updates, confirmations): ~โน0.30-0.35 each - Marketing conversations (promotions, broadcasts): ~โน0.70-0.80 each - Service conversations (customer-initiated): Free for first 1,000/month, then ~โน0.30 each - Authentication conversations (OTPs): ~โน0.25 each
A "conversation" is a 24-hour window. Multiple messages within that window count as one conversation.
**Typical small business monthly cost** (500 service + 200 marketing): โน2,000-5,000 in Meta fees plus BSP platform charges.
Common Mistakes to Avoid
1. **Not getting opt-in before marketing messages.** Meta can ban your number for spam reports. Always get explicit consent. 2. **Starting with too many templates.** Submit 5-10 initially. Add more as you learn what works. 3. **Ignoring quality rating.** Too many blocks or reports drops your rating, limiting sending capacity. Monitor your quality rating weekly. 4. **No human fallback.** Chatbots fail sometimes. Always have a clear path to a real person. 5. **Using API for personal messages.** The API is for business communication only.
The entire setup process takes 5-10 business days, mostly waiting for Meta's business verification.
