Problem Solved

This workflow addresses the challenge of automating the retrieval of user data during inbound calls. It enables voice agents to:

- Integrate seamlessly with Google Sheets, allowing for easy updates and management of user data.

Workflow Steps

  • Webhook Trigger: The workflow starts when a POST request is received at the specified webhook URL, which is set up to handle inbound calls from Retell.
    2. IP Whitelisting: The webhook filters requests based on a whitelisted IP address to ensure security.
    3. Data Extraction: The workflow extracts relevant information from the incoming webhook, particularly the caller's phone number.
    4. Google Sheets Query: It queries a Google Sheet to find the user associated with the provided phone number, retrieving necessary details such as first name, last name, and email.
    5. Response Formatting: The workflow formats the retrieved data into a JSON response that matches Retell's expected structure.
    6. Respond to Webhook: Finally, it sends the formatted response back to Retell, allowing the voice agent to use the dynamic variables in the call.
