ThunderPhone Call Logging to Google Sheets (n8n Workflow)

Automatically log ThunderPhone calls to Google Sheets with AI summaries—powered by an n8n workflow

This n8n workflow listens for completed ThunderPhone calls, retrieves the full call details, and appends a clean, structured row to your Google Sheets—including duration, status, an AI summary, the transcript, and a direct ThunderPhone dashboard link.

What this workflow does

• Triggers on call completion: When ThunderPhone sends a signed call-completed webhook for a phone or web call, the workflow starts.
• Fetches the completed call record: It retrieves call data such as duration, status, end reason, summary, and transcripts.
• Filters out test/simulation calls: So only real calls are logged to your sheet.
• Formats data for your sheet: Builds a row with key metadata, a combined transcript field, and a ThunderPhone dashboard link.
• Appends to Google Sheets: Adds the formatted row to the Calls tab.

Use cases

• Sales & support operations: Keep a searchable call history with transcripts and summaries for follow-ups.
• QA and coaching: Track outcomes (status/end reason) and review call content from a single dashboard.
• SaaS reporting: Export call metadata to Google Sheets for lightweight analytics and monitoring.
• Automation engineers: Standardize call logging across environments with an n8n-based workflow.

Technical details

• ThunderPhone integration: Uses the n8n-nodes-thunderphone / ThunderPhone trigger to receive signed webhooks and fetch call details.
• Google Sheets integration: Appends rows to the Calls sheet via OAuth.
• Workflow building blocks: Includes nodes such as set, filter, and a sticky note for setup guidance.

Setup requirements

Create a Google Sheets tab named Calls with headers: Call ID, Started at, Direction, From, To, Agent, Duration (s), Status, End reason, Summary, Transcript, Call link. Then deploy the workflow so your n8n instance is reachable over public HTTPS and ThunderPhone can register the webhook.
