This n8n workflow automates replying to Google Play Store reviews using AI.

It analyzes each review’s sentiment and tone and posts a human-like response — saving time for indie devs, founders, and PMs managing multiple apps.


💡 Use Cases

  • Respond to reviews at scale without sounding robotic
  • Prioritize negative sentiment feedback
  • Maintain consistent tone and support messaging
  • Free up time for teams to focus on product instead of ops

🧠 How it works

  • Uses the Play Store API to fetch new app reviews
  • Filters out reviews that have already been replied to
  • Analyzes sentiment using OpenAI GPT-4o
  • Passes sentiment and review context to an AI Agent node that crafts a reply
  • Replies are posted to Play Store via Google API
  • (Optional) Logs the reply to Slack for visibility

🛠️ Setup Instructions (Sticky notes included in the workflow)

1. HTTPS Node

  • Replace the package name with your app’s package ID
  • Add Google Service Account credentials
    → Create from Google Cloud Console with access to Play Console
    → Add to n8n Credential Manager

2. OpenAI Node

  • Add your OpenAI API key
    → GPT-4o or GPT-4o mini supported
    → Customize model or instructions if needed

3. AI Agent Node

  • Modify prompt to reflect your app name, tone, and feature set
    → E.g. polite, witty, casual, support-friendly, etc.
    → You can add reply conditions or logic for different types of reviews

4. Slack Node (Optional)

  • Configure Slack Webhook or OAuth credentials if you want reply logs
    → Otherwise, delete the node to simplify the workflow

⚡ Requirements

  • Google Play Developer Console access
  • Google Cloud Project with service account
  • OpenAI account (GPT-4o or mini)
  • (Optional) Slack workspace & app for logging
