APITube Brand Mentions Monitor: Sheets + Slack Alerts (n8n)

APITube Brand Mentions Monitor with Google Sheets + Slack alerts (n8n)

Stay ahead of your brand’s reputation: this n8n workflow checks the APITube News API every 15 minutes for new brand mentions, logs each article (with sentiment) into Google Sheets, and sends a Slack alert whenever an article’s sentiment score falls at or below your negative threshold.

What this workflow does

Built for consistent, low-effort monitoring, the workflow runs on a schedule and performs the following:

• Runs every 15 minutes to search for recent APITube News articles matching your configured brand name, language, lookback window, minimum source rank, and sorting preferences.
• Processes one item per article by splitting the API response so each mention becomes an individual workflow item.
• Prevents duplicates by removing articles already seen in previous executions using the article URL.
• Extracts and flattens key metadata, including title, URL, publication time, source details, entities, categories, and sentiment score/polarity.
• Appends results to Google Sheets as new rows in a worksheet with columns aligned to the workflow fields.
• Triggers Slack alerts when an article’s sentiment score is at or below your configured negative threshold, posting a formatted message to your selected Slack channel.

Use cases

• Monitor brand mentions for customer support signals and escalation opportunities.
• Track negative sentiment in near real time for marketing and PR teams.
