What Retell AI does

Retell AI runs realistic voice conversations. It can answer inbound calls or make outbound ones, follow a script, qualify the caller, and take actions like booking, all without a human.

Connecting it to GoHighLevel

The agent connects to GoHighLevel through API and webhooks. When it qualifies a lead or books a time, it updates the contact and fires the workflow, exactly as if a person did it.

Booking appointments

Give the agent access to your calendar availability and it can offer real open slots and book them, then trigger confirmations and reminders through GHL.

Where it shines

After-hours calls, overflow when you are busy, and instant response to new leads, the moments when calls usually go to voicemail and leads go cold.
