This comprehensive guide demonstrates how to build and test a voice agent using the Retell AI SDK in TypeScript. It walks through configuring the underlying LLM with a custom persona, creating the voice agent instance, and finally initiating both outbound phone calls and web calls through the API. This is essential for integrating AI-powered voice communication into customer service platforms, call centers, or telephony automation systems.

This skill provides a comprehensive guide for setting up and managing webhook endpoints for Retell AI. It allows developers to capture and process crucial call lifecycle events—such as call start, end, and analysis—as well as handle function calls triggered during live conversations. Use this when building sophisticated voice agents or call automation systems that require real-time backend interaction with Retell AI.

Guides API integration teams through retry logic helpers, outlining patterns, best practices, production-ready code, and validation for webhooks, SDKs, OAuth, and third-party APIs.

Expert skill for building high-performance, memory-safe systems, web services, and complex libraries using modern Rust (1.75+). Specializes in advanced async programming with Tokio, zero-cost abstractions, and mastering ownership and lifetime rules. Ideal for implementing scalable backend APIs, low-level networking, and performance-critical components where memory safety is paramount.
