Monitor low-rated WooCommerce reviews with Google Sheets, Slack and OpenAI

(Retail) Social Review Monitoring

This workflow automatically monitors WooCommerce product reviews, detects low-rated and approved reviews, checks whether the review already exists in Google Sheets, updates or inserts records accordingly, and sends a clear Slack alert generated using OpenAI for new low-rated reviews.

This workflow runs on a schedule, fetches WooCommerce product reviews, filters only approved reviews with low ratings (≤ 2 stars), checks if the review already exists in Google Sheets, and then:

• Updates the existing record if the review is already stored
• Generates a Slack alert using OpenAI and adds a new row if the review is new

You receive:

• Automated monitoring of customer reviews
• Centralized Google Sheets tracking for low-rated reviews
• Instant Slack alerts for new negative feedback

Ideal for support, product and operations teams who want fast visibility into unhappy customer feedback without manual checks.
