Automating Marketing Reports with n8n and Looker Studio

Description and use

Automating weekly marketing reports with n8n and Looker Studio, eliminating manual CSV export and chart recreation.

Problem

Marketing teams manually export CSVs from Meta Ads Manager, Google Ads, and GA4, fix dates, rebuild charts, spending an hour weekly and risking errors.

Outcome

Automates weekly marketing reporting, saving ~1 hour per week and increasing data reliability.

Workflow

• Pull Meta Ads data with HTTP Request node
• Pull GA4 data with Google Analytics node
• (Optional) Pull Google Ads data via API or fallback email reports
• Normalize data in a Code node
• Write normalized rows to Google Sheets
• Build Looker Studio dashboard linked to the Sheet
• Schedule workflow with cron trigger
• Add error handling and stale‑data checks

Evidence

"Meta returns actions as an array of {action_type, value} objects, not flat columns."

"The failure mode to expect here is the property-access step. If n8n returns a 403, it's almost always the service account missing the Viewer role in GA4, not your n8n config."

"The Google Ads API requires a developer token, and Google approves those only for accounts in good standing."
