Redialer · Read-only on Retell

Your Retell agent calls
people back. Easily.

When a caller asks for a callback, your agent doesn't know how to schedule it. We do — about 5 minutes per agent to wire up. We never modify your Retell account.

How redialer works · start to finish in four events

Marcus calls at 8:42 PM.
He gets called back at 10 AM tomorrow.

R Retell agent · 8:42 PM

Caller asks to be called back at 10 AM tomorrow.

Marcus calls into your Retell agent after-hours. Your agent listens, captures the requested time, and ends the call gracefully. Post-Call Extraction runs immediately.

caller=+1 306•••2014 requested=10:00 AM PT duration=1m 12s
R Retell agent · 8:42 PM · Post-call extraction

Your agent flips one Boolean. That's it.

You add a single Post-Call Extraction variable to your Retell agent: redialer.io_callback. Your agent sets it to true when a caller asks for a callback. Nothing else changes about your setup.

redialer.io_callback=true agent=A_8f3c…d12a
Redialer · 8:42 PM · Webhook

Redialer schedules the dial-back — timezone aware.

Retell fires its Post-Call webhook to a URL we generate for that specific agent. We compute the correct dial-back time (timezone, DST, business hours, quiet hours) and queue the outbound call.

webhook=200 OK scheduled=10:00 AM PT tz=America/Vancouver
Redialer · 10:00 AM tomorrow · Outbound dial

Marcus's phone rings. Your agent picks up where it left off.

At 10:00 AM, Redialer fires the outbound call through your same Retell agent. Marcus answers — your agent is already on the line, with the original conversation context.

The deal

Read-only. We never modify your Retell account.

Redialer uses your Retell API key to read your agents — names, IDs, and configuration metadata — so we can show you which agents are wired up and which still need a Boolean field. We don't write anything back. The Boolean and the webhook URL — those you add yourself. That's the deal.

  • Your API key is encrypted at rest and only used to list and read agent metadata.
  • No writes to prompts, tools, voices, custom functions, or any agent setting.
  • You can rotate or disconnect your key at any time from Settings — we drop all derived state.
  • Webhook deliveries are signature-verified. Per-agent webhook URLs, never shared.
