How to integrate WhatsApp Cloud API into your product
A practical path for SaaS founders and product teams. DAPS is an Official Meta Tech Provider and builds these integrations in production environments every week.
1. Decide the product job
Be clear whether WhatsApp is for support, outbound notifications, in-chat booking, payments follow-ups, or a full conversational UI. The job decides templates, opt-in rules, and backend events.
2. Set up Meta / WhatsApp access
- Business portfolio and WhatsApp Business Account
- Phone number and Cloud API app configuration
- Webhook verification endpoint on your backend
3. Build the message pipeline
- Inbound webhook receiver and signature validation
- Conversation / session store
- Outbound send queue with retries
- Template messages for business-initiated outreach
4. Connect your product data
Map WhatsApp events to your CRM, tickets, bookings, ecommerce orders, or SaaS user accounts so chat is not an isolated silo.
5. Launch checklist
- Opt-in and privacy language
- Human handoff path
- Rate limits, logging, and failed-delivery alerts
- Test number → production number cutover
