I need a turnkey, production-ready WhatsApp Business API SaaS that I can put in front of customers immediately. The platform has to handle true bulk messaging, surface meaningful marketing analytics, and enforce tiered access for Admin, Manager, and regular User accounts. Once you install it on my cloud instance, I want to: • Receive live API credentials and full documentation • See the first two test users onboarded end-to-end (signup, verification, initial campaign send) • Walk through campaign creation, contact import, template use, and real-time reporting dashboards • Confirm role-based permissions operate exactly as designed Native or webhook-level hooks into my existing CRM and customer-support platforms are required so that contact data, message history, and opt-in status stay in sync automatically. Compliance with WhatsApp Business policy—template approval flow, rate limiting, opt-out handling—must be baked in. A clean, responsive UI is expected, but stability, message deliverability, and clear API endpoints come first. Delivery is complete when the system is live, the API passes my Postman tests, and I can run one full marketing blast with analytics populated in the dashboard.
