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

Migrate one agent while preserving a rollback path

Export the current agent configuration and record its version, routing rule, and supported handoff behavior before making schema or prompt changes. Import the candidate into a preview environment, replay synthetic scenarios, and compare the redacted outcomes with the old version. Move a small canary route only after those checks pass; leave the previous configuration intact until the canary completion and escalation rates remain within the agreed bounds.
