API Whatsapp Gateway
What is fsn-wa-gateway? fsn-wa-gateway is a web-based WhatsApp Gateway application built with the Next.js (App Router) framework. This application allows users or third-party systems to send WhatsApp messages programmatically via the REST API. Main Architecture Frontend & Admin Panel: Uses Next.js for the user interface (Dashboard) and Admin pages. Database: Uses PostgreSQL with Prisma ORM to store user data, device status, message history, and daily quota. WhatsApp Engine (VPS): Integrated with an external VPS based on the Baileys library that acts as a connecting engine to the WhatsApp protocol (managing connections, QR Code scanning, pairing codes, and message delivery). Key Features Multi-Device Management: Users can register their WhatsApp devices, receive a QR Code/pairing code for login, and monitor the device's connection status in real time. REST API & API Keys: Users can create unique API keys to integrate automatic WhatsApp messaging from external applications (using the /api/v1/messages/send endpoint). Daily Quota & Rate Limiting System: Limits the number of daily messages (DailyQuota) and delivery speed according to the user's subscription plan. Subscription Management (SaaS): Provides subscription plans (Free, Basic, Pro) integrated with the Pakasir Payment Gateway via webhooks for automatic activation. Delivery Log & Monitoring: Tracks the delivery status of each message (queued, delivered, successful, or failed) along with error messages if any occur. System & Admin Notifications: Internal bell notifications for users and an automatic notification system via WhatsApp directly to the admin number when important events occur (such as new subscription transactions).
