Daily Ad Spend Monitor: Google Sheets to Slack Alerts

This n8n workflow fetches raw ad spend data from a Google Sheet, aggregates daily totals, and triggers a Slack notification if the spend surpasses a configurable $100 threshold. It supports both scheduled daily runs via cron-like triggers or manual execution for testing, ensuring flexibility for production and development environments.

Key benefits include real-time budget oversight without manual spreadsheets, reducing errors and saving hours of monitoring time for marketing teams. The workflow integrates seamlessly with Google Sheets API via OAuth2 and Slack bots, requiring minimal setup once credentials are configured. It handles data summarization intelligently, focusing only on relevant daily metrics to avoid alert fatigue.

Ideal use cases: Marketing agencies managing client ad campaigns, e-commerce teams tracking PPC budgets, or any business needing proactive spend alerts. Copy the provided sample sheet to get started quickly, customize the threshold, and deploy for near real-time insights that prevent overspending and optimize ROI.
