SaaS Tool Upgrade for Meta WhatsApp Business API Integration Objective: Upgrade the existing SaaS tool (currently built on Laravel) to integrate Meta’s official WhatsApp Business API (Cloud API), replacing third-party/self-service APIs, to provide a direct, scalable, and compliant solution for customer onboarding and messaging. Scope of Work: 1. Backend Integration (Laravel): • Integrate Meta WhatsApp Business Cloud API for: • Business onboarding & account linking. • Sending messages (session & template messages). • Template creation, submission, and approval workflow. • Implement webhook handling for: • Delivery receipts. • Message status updates. • Incoming customer messages. • Role-based access control for businesses & admins. 2. Frontend Development (Customer Dashboard): • Customer onboarding flow (Business verification, phone number registration, access token management). • UI for sending messages: • One-to-one & bulk messaging. • Template selection & personalization. • Template management interface: • Create, edit, submit, and track approval status. • Real-time reports & analytics: • Message delivery reports. • Usage tracking & credits consumption. 3. System Enhancements: • Multi-tenant architecture to allow multiple businesses to onboard independently. • Credit/billing module (charge per message, monthly subscription, GST support). • Notifications & alerts (template approval, low balance, failed messages). • Scalable webhook system for high message volumes. Deliverables: • Fully functional SaaS platform integrated with Meta’s WhatsApp Business Cloud API. • Admin panel for managing businesses, templates, and usage. • Customer dashboard with onboarding, messaging, and reporting capabilities. • Webhook-based real-time updates. • Technical documentation (integration flow, deployment, and usage guide). Tech Stack: • Backend: Laravel (PHP) • Frontend: Blade / Vue.js / React (depending on existing system setup). • Database: MySQL / MariaDB. • APIs: Meta WhatsApp Business Cloud API. Timeline: 6–8 weeks (depending on current system structure & features). ⸻ This will make your SaaS work like 360Dialog or WATI, but directly on Meta Cloud API with full ownership.
