n8n Meta Ad Library Monitor: Scavio + OpenAI to Sheets & Slack

Watch competitor Meta ads change—automatically

This n8n workflow monitors a competitor’s active Meta Ad Library ads using Scavio, analyzes each newly discovered ad with OpenAI into a structured insight, then logs the results to Google Sheets and sends a formatted alert to Slack—on a daily schedule (or on-demand).

What this workflow does

• Runs daily (or manually) and loads your configuration for the competitor, Google Sheets, and Slack.
• Fetches active Meta Ad Library ads via the Scavio Meta Ad Library API, including pagination through additional result pages up to your configured maximum.
• Detects new ads by splitting the response into individual ads and skipping items already seen in previous executions (with an option to process a limited sample for testing).
• For each new ad, sends the ad’s copy, headline, CTA, landing URL, format, and metadata to OpenAI to generate strict JSON analysis.
• Validates and merges the AI output back into a single intelligence record per ad, then:
  • Appends each record as a new row in Google Sheets
  • Posts a Slack alert containing the same formatted insight

Use cases

• Marketing/SaaS teams tracking competitor messaging changes without manual scraping.
• Automation engineers building an ongoing “ad intelligence” pipeline across Meta, Sheets, and Slack.
• Operators who want structured creative breakdowns (hook, offer, angle, CTA strategy) for faster testing decisions.

Technical details

• Scavio community node (n8n-nodes-scavio) on a self-hosted n8n instance with community nodes enabled.
• Node/logic building blocks include: if, set, code, limit, merge, and slack.
• OpenAI produces strict JSON analysis (hook, offer, messaging angle, audience, CTA strategy, creative observations, and why it matters).
• Google Sheets OAuth2 integration to append intelligence rows; Slack OAuth2 to post alerts.

Perfect if you’re looking for an n8n automation workflow that turns Meta Ad Library changes into actionable, structured competitor insights—fast.
