WhatsApp Business API Setup: Complete Tutorial
Step-by-step guide to setting up WhatsApp Business API for your business. Learn about verification, templates, webhooks, and best practices for successful messaging.
Prerequisites
Before setting up your WhatsApp Business API, ensure you have:
- A Facebook Business Manager account
- A verified business phone number
- Business registration documents
- A Business Solution Provider (we recommend ChatterKart)
Step 1: Business Verification
Facebook requires business verification before granting API access. This process typically takes 24-48 hours and ensures compliance with WhatsApp's business policies.
Required Documents
- Business registration certificate
- Tax identification documents
- Proof of business address
- Website or business profile verification
Step 2: Phone Number Setup
Your WhatsApp Business phone number will be the sender ID for all messages. Choose wisely - this number represents your brand and can't be easily changed later.
Step 3: Message Templates
All marketing messages must use pre-approved templates. Create templates for common scenarios like order confirmations, promotional offers, and customer support responses.
Template Best Practices
- Use conversational, friendly language
- Include personalization variables like customer name
- Add clear call-to-action buttons
- Keep messages concise and valuable
Next Steps
Once your API is set up, you can start building campaigns, automations, and customer journeys that leverage WhatsApp's incredible engagement rates.
