How it works

How to set up Snowflake to Facebook Ads in Weld.
Guided setup in 5 steps.

Full setup guide
  1. Step 01

    Connect your database

    Add Snowflake 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 Facebook Ads. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Facebook Ads expects. You can preview results before activating.

  3. Step 03

    Connect Facebook Ads

    Authenticate Facebook Ads 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 Facebook Ads.

  4. Step 04

    Map fields and configure sync

    Map your SQL columns to Facebook Ads 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: Snowflake and Facebook Ads

ELT (Extract, Load, Transform) moves data from Facebook Ads into Snowflake 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 Snowflake and pushes it into Facebook Ads 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 Snowflake and Facebook Ads.

Sync modes
Choose between insert, update, or upsert sync modes when pushing data to Facebook Ads. Upsert is recommended to avoid duplicates.
Rate limits
Weld respects Facebook Ads'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.
