TypeScript SDK | duochat SDK Documentation

TypeScript SDK

The TypeScript SDK offers a strongly-typed and flexible way to integrate WhatsApp messaging into Node.js applications. It provides better IntelliSense, compile-time safety, and works seamlessly with modern TypeScript projects.

Both SDKs support the same features and endpoints, so functionality is identical across them.
