Auto-Reply to Google Play Store Reviews with GPT-4o (Sentiment Analysis)

This n8n workflow automates the process of responding to Google Play Store reviews using AI, specifically GPT-4o for sentiment analysis and reply generation. It aims to streamline customer support and ensure timely, contextually appropriate responses to app reviews.

What it does

  1. Schedules Review Checks: Periodically checks for new Google Play Store reviews.
  2. Fetches Reviews: Makes an HTTP request to retrieve recent reviews from the Google Play Store API.
  3. Analyzes Sentiment with GPT-4o: For each review, it uses an OpenAI Chat Model (GPT-4o) to determine the sentiment (positive, negative, neutral) and extract key topics.
  4. Generates AI-Powered Replies: Based on the sentiment and topics, it crafts a suitable reply using an AI Agent (powered by GPT-4o) and a Simple Memory to maintain context.
  5. Filters for Unreplied Reviews: Identifies reviews that have not yet been replied to.
  6. Posts Replies: Sends the AI-generated replies back to the Google Play Store via an HTTP request.
  7. Notifies via Slack (Optional): Can be extended to send notifications to a Slack channel about new reviews and their automated replies.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Google Play Store API Access: Credentials and API access to interact with the Google Play Store Developer API to fetch reviews and post replies. This typically involves setting up a Google Cloud Project and enabling the Google Play Developer API.
  • OpenAI API Key: An API key for OpenAI (specifically for GPT-4o) to perform sentiment analysis and generate replies.
  • Slack Account (Optional): If you wish to enable Slack notifications, you will need a Slack account and an n8n Slack credential configured.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • HTTP Request Nodes: Configure the "HTTP Request" nodes (nodes 19 and 1250) with your Google Play Store API credentials and endpoints for fetching reviews and posting replies. This will involve setting up authentication (e.g., OAuth2 or API Key) as required by Google.
    • OpenAI Chat Model (Node 1153): Set up your OpenAI API key credential.
    • AI Agent (Node 1119): Ensure it's configured to use the OpenAI Chat Model and Simple Memory.
    • Slack (Node 40 - Optional): If using, configure your Slack API credential.
  3. Adjust Schedule (Node 839): Modify the "Schedule Trigger" node to define how often you want the workflow to check for new reviews (e.g., every hour, daily).
  4. Customize AI Prompts: Review the prompts within the "OpenAI Chat Model" and "AI Agent" nodes to fine-tune the sentiment analysis and reply generation to match your brand's tone and specific needs.
  5. Activate the Workflow: Once configured, activate the workflow. It will start running automatically based on your defined schedule.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
