Everything needed for WhatsApp integration

Your application talks to one clean API. WhatsAppDev handles sessions, message queues, retries, delivery state and webhook delivery.

API

Simple REST API

Send messages from PHP, Node.js, Python, mobile backends or any system capable of making an HTTP request.

⚡

Fast asynchronous delivery

Requests are queued immediately and processed continuously, making the platform suitable for transactional and OTP-like messages.

↗

Real-time webhooks

Receive notifications when messages are sent, delivered, read, failed or when customers reply.

Multiple WhatsApp accounts

Connect separate WhatsApp accounts and select the required session using secure public identifiers.

✓

Delivery tracking

Track messages through queued, processing, sent, delivered, read and failed states.

🔑

Secure API keys

API secrets are securely authenticated while internal numeric database identifiers remain hidden from integrations.
