GA4 + Bruin

Source

Ingest GA4 data into your warehouse with incremental loading, quality checks, and full lineage. Defined in YAML, version-controlled in Git.

For business teams

What you get

Analysis beyond built-in reports
Join GA4 behavioral data with revenue, support, and CRM data. Answer questions GA4 alone can't.
Trusted behavioral data
Quality checks catch tracking gaps, duplicate events, and missing timestamps before they corrupt your models.
Self-serve for analysts
GA4 data lands in your warehouse where analysts already work. No more exporting, no more waiting.
Real user journeys
Combine GA4 events with purchase and support data to see the full customer journey, not just the product funnel.

For data & engineering teams

How it works

Event schema validation
Check for null event IDs, missing timestamps, and duplicate events on every sync. Catch tracking issues at ingestion.
YAML-defined, Git-versioned
Your GA4 pipeline is a YAML file. Review in PRs, deploy with CI/CD, roll back with git revert.
SQL + Python transforms
Transform raw GA4 events into funnels, cohorts, and user journeys with SQL or Python — in the same pipeline.
Dependency-aware scheduling
Bruin resolves pipeline dependencies automatically. Transforms only run after GA4 data has landed.

Before you start

Google Analytics 4 property

Service account with Viewer role

GA4 Data API enabled in GCP

Step 1

Add your GA4 connection

Connect using Google Analytics 4 service account. Add this to your Bruin environment file — credentials are stored securely and referenced by name in your pipeline YAML.

Parameters

credentials_pathPath to Google service account JSON key
property_idGA4 property identifier

connections:
  ga4:
    type: ga4
    uri: "ga4://credentials_path@property_id"

Step 2

Create your pipeline

Define a YAML asset that tells Bruin what to pull from GA4 and where to land it. This file lives in your Git repo — reviewable, version-controlled, and deployable with CI/CD.

Available tables

eventssessionsusersconversionspagestraffic_sources

name: raw.ga4_events
type: ingestr

parameters:
  source_connection: ga4
  source_table: 'events'
  destination: bigquery

Step 3

Add quality checks

Add column-level and custom SQL checks to your GA4 data. If a check fails, the pipeline stops — bad data never reaches downstream models or dashboards.

Catch duplicate events and missing timestamps

Validate event freshness — stale data gets flagged

Ensure event IDs are unique across syncs

columns:
  - name: event_id
    checks:
      - name: not_null
      - name: unique
  - name: event_timestamp
    checks:
      - name: not_null

custom_checks:
  - name: data is fresh
    query: |
      SELECT MAX(event_timestamp) >
        TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 24 HOUR)
      FROM raw.ga4_events

Step 4

Run it

One command. Bruin connects to GA4, pulls data incrementally, runs your quality checks, and lands clean data in your warehouse. If a check fails, the pipeline stops — bad data never reaches downstream.

Backfill historical data with --start-date

Schedule with cron or trigger from CI/CD

Full lineage from GA4 to your dashboards
