About This Template
Turn every sales meeting into a coaching opportunity. This workflow automatically analyzes tldv meeting recordings using OpenAI (GPT-4) to provide instant, actionable feedback to your sales team.

It acts as a virtual sales coach, evaluating key performance metrics like listening skills, question quality, and customer engagement without requiring a manager to listen to every call.

How It Works
Trigger: The workflow starts automatically when a meeting transcript is ready in tldv (via Webhook).
Data Retrieval: It fetches the full meeting details and transcript from the tldv API.
AI Analysis: GPT-4 analyzes the conversation to score the sales rep's performance (e.g., Speaking vs. Listening balance, Clarity, Next Steps).
Delivery:
Slack: Sends a summary notification and a detailed markdown report to the team channel.
Google Sheets: Archives the scores and meeting data for long-term tracking.

Who It’s For
Sales Managers:** To monitor team performance and identify coaching needs at scale.
Account Executives:** To get immediate feedback on their calls and self-correct.
Sales Enablement:** To track KPI trends over time.

Requirements
n8n** (Cloud or Self-hosted)
tldv (Business Plan)** for API/Webhook access
OpenAI API Key** (GPT-4 access recommended)
Slack** Workspace
Google Sheets**

Setup Steps
Credentials: Configure "Header Auth" for tldv (x-api-key) and OpenAI (Authorization). Connect OAuth for Slack and Google Sheets.
Webhook: Copy the Production URL from the first node (Webhook) and add it to your tldv Settings > Integrations > Webhooks (select Event: TranscriptReady).
Google Sheets: Create a sheet (e.g., named Sales Feedback) with columns for Meeting Name, Score, Summary, etc.
Note: Be sure to update the Google Sheets node in the workflow to match your specific Sheet Name and Column headers.
