How it works

How to set up Google BigQuery to Klaviyo in Weld.
Guided setup in 5 steps.

Full setup guide
  1. Step 01

    Connect your cloud data warehouse

    Add Google BigQuery as a data source in Weld with connection credentials that grant read access. Credentials are stored encrypted and never logged.

  2. Step 02

    Define your transformation

    Write a SQL query or dbt model that selects and transforms the data you want to push to Klaviyo. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Klaviyo expects. You can preview results before activating.

  3. Step 03

    Connect Klaviyo

    Authenticate Klaviyo as a reverse ETL destination. Weld supports OAuth or API key authentication depending on the connector. Once connected, Weld automatically discovers the available objects and fields in Klaviyo.

  4. Step 04

    Map fields and configure sync

    Map your SQL columns to Klaviyo fields using Weld's visual mapper. Choose a sync mode: insert to create new records, update to modify existing ones, or upsert to do both. Then set a schedule from every 5 minutes to daily.

  5. Step 05

    Activate and monitor

    Enable the sync and monitor it from the Weld dashboard. Track record counts, sync duration, and error rates in real time. Configure Slack or email alerts so you're notified immediately if a sync fails or encounters data quality issues.

ELT

ELT vs. reverse ETL: Google BigQuery and Klaviyo

ELT (Extract, Load, Transform) moves data from Klaviyo into Google BigQuery for analytics. It's about centralizing data in your warehouse so analysts can query and join it with other sources.

Reverse ETL does the opposite. It takes data that's already in Google BigQuery and pushes it into Klaviyo so operational teams can act on it. This is the approach used on this page.

Many teams use both: ELT to centralize data in the warehouse, and reverse ETL to activate that data back in business tools. Weld supports both directions between Google BigQuery and Klaviyo.

Klaviyo to Google BigQuery
Sync modes
Choose between insert, update, or upsert sync modes when pushing data to Klaviyo. Upsert is recommended to avoid duplicates.
Rate limits
Weld respects Klaviyo's API rate limits and automatically throttles requests to avoid hitting quotas.
Data freshness
Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security
All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
