Automated User Data Retrieval for Retell Webhooks

This n8n workflow streamlines the process of integrating Retell AI’s inbound call webhooks with personalized user data retrieval from Google Sheets. When Retell receives an inbound call, it triggers the webhook, which is processed by n8n. The workflow extracts the caller’s phone number, looks up additional user information in a designated Google Sheet, and formats this data in a JSON response. This response dynamically populates Retell’s voice agent prompts with user-specific variables, enabling more personalized and context-aware interactions. Practical scenarios for this workflow include customer support automation, lead qualification, or personalized marketing campaigns via voice calls. It provides a simple yet powerful way to enhance voice agent interactions with contextual data, making users feel more engaged and understood.
