The skill
Retell AI upgrade migration for voice agents and telephony: upgrading the retell-sdk npm package in TypeScript, pinning a candidate SDK version, running synthetic create-call, retrieval, error, and webhook checks against a development agent, and keeping the prior lockfile and agent version for rollback. Use when upgrading or migrating the Retell AI SDK or changing voice agent API integrations, and the RETELL_API_KEY setup is already in place.

Overview
Implementation patterns for Retell AI upgrade migration — voice agent and telephony platform.
Prerequisites
- Completed
retellai-install-authsetup
Instructions
Step 1: SDK Pattern
import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });
const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);
Output
- Retell AI integration for upgrade migration
Error Handling
| Error | Cause | Solution |
|---|---|---|
| 401 Unauthorized | Invalid API key | Check RETELL_API_KEY |
| 429 Rate Limited | Too many requests | Implement backoff |
| 400 Bad Request | Invalid parameters | Check API documentation |
Examples
Upgrade an SDK through a compatibility canary
Pin the candidate SDK version in a branch and run the development agent suite against synthetic create-call, retrieval, error, and webhook scenarios. Record the old and new package versions and any changed request shapes, then deploy a preview configuration before altering production dependencies. Keep the prior lockfile and agent version available until the canary has met its error and latency limits, so rollback does not require reconstructing the old runtime.
