Client Review Collection & Sentiment Analysis with HighLevel, GPT-4o, Gmail & Slack

📘 Description: This automation streamlines client review collection and sentiment summarization for Techdome using HighLevel CRM, Azure OpenAI GPT-4o, Gmail, Slack, and Google Sheets. It starts by pulling recently won deals from HighLevel, then generates and sends AI-written HTML review request emails with built-in Google Review and feedback form links. After waiting 24 hours, it fetches the client’s reply thread, summarizes the sentiment using GPT-4o, and posts a clean update to Slack for team visibility. Any failures—API errors, empty responses, or data validation issues—are logged automatically to Google Sheets for full transparency and QA. The result: a fully hands-free Client Appreciation + Feedback Intelligence Loop, improving brand perception and internal responsiveness.
