How to Connect n8n to Google Ads: Automate Reporting and Campaign Alerts (2025)
Google Ads generates a firehose of data, but most teams still check it by logging in and squinting at dashboards. Connecting Google Ads to n8n lets you pull metrics on a schedule, turn them into readable reports, and get alerted the moment spend spikes or performance drops. Here's how to set it up and what to automate.
Connecting n8n to the Google Ads API
Google Ads uses OAuth 2.0 plus a developer token. In practice you set up Google OAuth credentials, obtain a Google Ads developer token from your manager account, and authorize n8n to query the account. Once connected, n8n can run GAQL (Google Ads Query Language) queries to pull exactly the metrics and dimensions you need.
If you manage multiple accounts under an MCC, you specify the customer ID per query, so a single connection can report across your whole portfolio. The HTTP Request node against the Google Ads API gives you full flexibility for any report shape.
Pulling the metrics that matter
The power of GAQL is that you fetch precisely what you want — impressions, clicks, cost, conversions, ROAS — sliced by campaign, ad group, or day. n8n runs the query on a schedule and hands you structured rows ready to transform, chart, or narrate.
Because it's all data in a workflow, you can join Google Ads numbers with GA4 sessions and CRM revenue to build a true picture of what your spend actually produces — not just platform-reported conversions.

Automations: reports and alerts
Two automations deliver most of the value. First, scheduled reporting: every Monday, pull the week's numbers, have an AI node write a plain-language narrative ('spend up 12%, CPA improved, campaign X is your best performer'), and deliver it to Slack or email. No one has to build the deck.
Second, monitoring: check key metrics daily and fire an alert if spend exceeds a threshold, a campaign's conversions collapse, or ROAS drops below target. That turns Google Ads from something you hope someone is watching into a system that tells you when to look.
Final thoughts
Connected to n8n, Google Ads reporting stops being a manual chore and becomes an automated feed of insight and alerts. Start with a weekly AI-narrated report, add spend and performance alerts, and you'll always know what your budget is doing without logging in.
