QR Code Login
Connect an existing WhatsApp number in seconds with a secure QR pairing flow.
WAStack's QR-based login eliminates the complex onboarding process required by the official WhatsApp Business API. Instead of waiting for approval, migrating numbers, or dealing with BSP restrictions, you can connect your existing WhatsApp number in under 60 seconds.
The process is simple: create a session in your WAStack dashboard, scan the displayed QR code with your WhatsApp app, and your number is instantly paired. Once connected, you get full access to REST APIs for sending and receiving messages, webhook subscriptions for real-time events, and automation tools for building workflows.
The QR pairing uses WhatsApp's native multi-device protocol, meaning the connection is secure, encrypted, and stable. Your primary phone doesn't need to stay online for the session to remain active.
