Webhook Automate

This workflow is ideal for:

• Voice Agent Developers: Those building voice agents with Retell who need to dynamically fetch user information based on phone numbers.
• Customer Support Teams: Teams looking to enhance their call handling by providing personalized responses based on caller data.
• Business Analysts: Individuals who wish to analyze call data and user interactions efficiently.
• Small Business Owners: Owners who want to automate customer interactions without extensive technical knowledge.

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

• Dynamically populate user information during calls, enhancing the customer experience.
• Reduce manual data entry, saving time and minimizing errors.
• Integrate seamlessly with Google Sheets, allowing for easy updates and management of user data.

1. 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.
