Wazen
Wazen is a WhatsApp API for developers that sends and receives WhatsApp messages through a simple REST API. It is built for teams that need reliable messaging at scale, and its site describes it as a complete platform for developers working on WhatsApp.
Its messaging API supports text, images, videos, audio, and documents. Wazen also includes a Smart Warming Module that adjusts message pacing based on session maturity for deliverability, real-time webhooks for delivery updates, read receipts, and session events, intelligent rate limiting with platform-wide adaptive pacing, and an MCP server that lets AI agents interact with WhatsApp through the Model Context Protocol. The service says messages can be sent in one API call and that there is no complex setup.
Official SDKs are provided for TypeScript, Python, .NET, and PHP. The TypeScript SDK is described as a Node.js SDK with full TypeScript support, tree shaking, and zero config; the Python SDK offers sync and async clients and is fully typed; the .NET SDK targets .NET 8.0+ and uses System.Text.Json; and the PHP SDK includes Guzzle HTTP client, a Laravel service provider, and facade support. The FAQ says Wazen connects to WhatsApp through dedicated numbers and that any WhatsApp-enabled phone number can be connected through a QR code pairing process, with dedicated numbers recommended for best results.
Wazen offers a 3-day free trial for new users, with no credit card charged during the trial period. Its pricing page lists annual plans called Starter at £49 per year for 1 WhatsApp session, Pro at £149 per year for 3 sessions, and Business at £349 per year for 10 sessions; each includes the full REST API, Group & Channel API, and MCP server access.
