n8n App Review Monitor: 1–2★ Alerts to Slack (App & Google Play)

Get alerted to bad app reviews every morning—automatically

This n8n workflow monitors both your App Store and Google Play reviews and sends 1–2★ complaint alerts straight to Slack. It checks new reviews daily at 08:00, filters for the lowest ratings with words in them, and posts each new unhappy review with store, rating, version, and country.

What this workflow does

• Runs daily at 08:00 using a Schedule trigger.
• App Store check: calls the App Store Reviews Scraper via core HTTP Request node (POST to run-sync) using appIds and countries.
• Google Play check: calls the Google Play Reviews Scraper via another HTTP Request node using your Android package name plus languages.
• Merges both stores (append) into one review list.
• Keeps new 1–2★ reviews only: a Code node normalizes App Store and Play row shapes, keeps rows with text, and drops any previously seen store|review_id pairs using a static key set (5,000 keys).
• Posts to Slack: one message per new review, including store, rating, version, and country.
• If there are no new complaints, it does nothing (NoOp).

Use cases

• Mobile PMs want early visibility into negative feedback across iOS and Android.
• Support leads use Slack alerts to triage recurring issues from low-star reviews.
• Indie developers reduce review response lag by routing 1–2★ feedback to the team channel.
