What this skill does
Retell AI Observability Overview Implementation patterns for Retell AI observability — voice agent and telephony platform. Prerequisites Completed retellai-install-auth setup Instructions Step 1: SDK Pattern Output Retell AI integration for observability 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 Alert on a regression while protecting call content Emit structured metrics for call completion, transfer outcome, latency, and provider errors using agent version and environment as bounded labels. When an alert fires, link the affected call identifiers to a restricted investigation record instead of attaching transcripts to the dashboard. Compare a synthetic call against the last known-good version, then make one reversible routing or configuration change and watch the same metrics through the defined recovery window.
