What this skill does
Retell AI Reliability Patterns Overview Implementation patterns for Retell AI reliability patterns — voice agent and telephony platform. Prerequisites Completed retellai-install-auth setup Instructions Step 1: SDK Pattern Output Retell AI integration for reliability patterns 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 Design a safe fallback for a dependent CRM outage Give the voice flow a short, explicit timeout for CRM lookup and a fallback response that either schedules a follow-up or transfers to a human queue. Test the fallback by making the preview CRM endpoint return a controlled error, then confirm no call is retried or double-booked. Track the fallback rate separately from general call failures and remove the temporary routing change only after the dependency and a synthetic recovery call both succeed.
