Connect Retell Voice Agents to n8n Custom Functions

Capture Retell Voice Agent webhooks in n8n to trigger custom logic like API calls, CRM updates, or dynamic responses during calls.

This workflow enables seamless integration between Retell Voice Agents and n8n by capturing POST webhooks triggered whenever a Custom Function node is reached in the agent's conversation flow. It processes incoming data from Retell, such as call context and parameters, allowing you to execute any custom logic—calling external APIs, booking meetings, updating CRMs, generating AI responses, or performing database operations—before sending a structured response back to the agent in real-time.
