Why WhatsApp for Support?
WhatsApp has 2 billion users worldwide. In many markets, it is the primary communication channel. Offering WhatsApp support meets customers where they already spend their time.
WhatsApp Business API vs. WhatsApp Business App
The WhatsApp Business App is for small businesses handling messages manually. The WhatsApp Business API is for companies that need to integrate WhatsApp with their help desk, CRM, or automation tools. You need the API for proper support integration.
Getting API Access
Apply through a WhatsApp Business Solution Provider (BSP) like Twilio, MessageBird, or 360dialog. The approval process takes 1-2 weeks and requires business verification.
Message Templates and Session Windows
WhatsApp has a 24-hour customer service window. After a customer messages you, you can reply freely for 24 hours. Outside this window, you can only send pre-approved message templates.
Submit templates for common scenarios: ticket confirmation, status updates, follow-ups. Templates need WhatsApp approval before use.
Connecting to Your Help Desk
Most modern help desks, including Helpzen, offer native WhatsApp integration. Connect your WhatsApp Business API account, map it to a channel in your unified inbox, and incoming WhatsApp messages become tickets automatically.
Compliance and Best Practices
- Always get opt-in consent before sending messages
- Respect the 24-hour session window
- Do not use WhatsApp for marketing blasts
- Include opt-out instructions in templates
- Maintain GDPR/CCPA compliance for customer data
