Retell AI Migration Deep Dive

Overview

Implementation patterns for Retell AI migration deep dive — voice agent and telephony platform.

Prerequisites

• Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list(); console.log(Agents: ${agents.length});

## Output

- Retell AI integration for migration deep dive

## 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.
