# Google Analytics 4 (GA4)

Google Analytics 4 (GA4) is Google's analytics platform for tracking user behavior across websites and apps. It uses an event-based data model to capture how visitors interact with your content — from page views and sessions to conversions and e-commerce transactions. By connecting GA4 to Coupler.io, you can automatically export your analytics data to spreadsheets, BI tools, or databases without any manual work.

## Why connect Google Analytics to Coupler.io?

* **Automate reporting** — Schedule regular data refreshes so your dashboards and spreadsheets always reflect the latest website or app performance.
* **Combine with other sources** — Merge GA4 data with Google Ads, Facebook Ads, CRM, or e-commerce data for a complete view of your marketing funnel.
* **Overcome GA4 interface limits** — The GA4 UI limits you to a handful of dimensions and metrics at a time. Coupler.io lets you build custom reports with up to 9 dimensions and 10 metrics per data flow.
* **Flexible destinations** — Export to AI tools like Claude or ChatGPT, Google Sheets, Excel, BigQuery, Looker Studio, or other supported destinations.

## Prerequisites

* A Google account with access to at least one **GA4 property** in [Google Analytics](https://analytics.google.com/)
* **Viewer** (or higher) permissions on the GA4 property you want to pull data from
* A Coupler.io account

## Quick start

{% hint style="success" %}
Start with the default metrics — Views, Total users, New users, Event count, and Key events — with the Date dimension for the last 60 days (default). Proceed to the Data sets to get a quick snapshot of your website performance and verify everything is connected correctly, or simply ask the Coupler AI agent to summarize the data.
