What this skill does
Retell AI Upgrade Migration Overview Implementation patterns for Retell AI upgrade migration — voice agent and telephony platform. Prerequisites Completed retellai-install-auth setup Instructions Step 1: SDK Pattern Output Retell AI integration for upgrade migration Error Handling Error Cause Solution ------- ------- ---------- 401 Unauthorized Invalid API key Check RETELLAPIKEY 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.
