What this skill does
Retell AI Architecture Variants Overview Implementation patterns for Retell AI architecture variants — voice agent and telephony platform. Prerequisites Completed retellai-install-auth setup Instructions Step 1: SDK Pattern Output Retell AI integration for architecture variants 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 Choose a queue-backed architecture for bursty inbound calls For a campaign that creates short spikes, keep the public number attached to a stable routing layer and place CRM enrichment behind an asynchronous queue. Start with a preview agent that records only synthetic test calls, set a clear timeout for the enrichment request, and configure a human-transfer fallback. Measure latency and transfer rate during the canary before selecting the variant for production traffic.
