Seamless Retell Voice Agent Integrations with n8n
detail.loadingPreview
Empower your Retell Voice Agents by connecting them to powerful custom logic and real-time workflows via n8n. This integration allows your agents to trigger actions, access external data, and generate dynamic responses, significantly expanding their capabilities.
About This Workflow
This n8n workflow template is designed to bridge the gap between Retell's advanced voice agents and your custom backend logic. By leveraging Retell's Custom Functions, this workflow receives webhooks whenever a function is invoked. It then processes the incoming data, allowing you to implement complex automation, API integrations, or AI-driven responses. The workflow concludes by sending a tailored response back to the Retell agent, ensuring a seamless conversational experience. This template provides a solid foundation for creating more intelligent and functional voice assistants that can interact with your existing systems and data.
Key Features
- Real-time Webhook Integration: Trigger n8n automations directly from Retell Voice Agents using Custom Functions.
- Dynamic Response Generation: Customize responses sent back to the voice agent based on processed data or external logic.
- Extensible Logic: Easily integrate third-party APIs, databases, or AI models within your n8n workflow.
- Data Processing Capabilities: Capture and manipulate call context and function parameters for intelligent actions.
- Simplified Setup: Comes with explanatory sticky notes and a pre-built Retell agent example for quick deployment.
How To Use
- Import the Workflow: Add this n8n workflow to your n8n instance.
- Configure the Webhook Node: Note the
pathparameter in the Webhook node (e.g.,hotel-retell-template). This will be part of your webhook URL. - Obtain Webhook URL: Construct your full webhook URL using your n8n instance address and the webhook path (e.g.,
https://your-instance.app.n8n.cloud/webhook/hotel-retell-template). - Configure Retell Custom Function: In your Retell agent's conversation flow, add a Custom Function node. Paste your n8n webhook URL into the function configuration.
- Modify Logic (Optional): Adjust the
Set responsenode or add/replace nodes in your n8n workflow to implement your desired custom logic (e.g., API calls, data manipulation). - Deploy and Test: Deploy your Retell agent and initiate a conversation to test the integration. The voice agent will now trigger your n8n workflow.
