Hardal + Bruin

Source

Ingest Hardal 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 Hardal behavioral data with revenue, support, and CRM data. Answer questions Hardal 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
Hardal data lands in your warehouse where analysts already work. No more exporting, no more waiting.
Real user journeys
Combine Hardal 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 Hardal pipeline is a YAML file. Review in PRs, deploy with CI/CD, roll back with git revert.
SQL + Python transforms
Transform raw Hardal 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 Hardal data has landed.

Before you start

Hardal API key

Step 1

Add your Hardal connection

Connect using API key. Add this to your Bruin environment file, credentials are stored securely and referenced by name in your pipeline YAML.

Parameters

api_keyHardal API key for authentication

connections:
  hardal:
    type: hardal
    uri: "hardal://?api_key=<api_key>"

Step 2

Create your pipeline

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

Available tables

eventssessionsvisitorsconversions

name: raw.hardal_events
type: ingestr

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

Step 3

Add quality checks

Add column-level and custom SQL checks to your Hardal 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.hardal_events

Step 4

Run it

One command. Bruin connects to Hardal, 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 Hardal to your dashboards
