How to set up Amazon Redshift Cluster to Customer.io in Weld
Connect your cloud data warehouse
Add Amazon Redshift Cluster as a data source in Weld by providing your connection credentials. Weld connects securely using encrypted tunnels and never stores raw credentials — only the OAuth token or connection string needed for read access.
Define your transformation
Write a SQL query or dbt model that selects and transforms the data you want to push to Customer.io. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Customer.io expects. You can preview results before activating.
Connect Customer.io
Authenticate Customer.io 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 Customer.io.
Map fields and configure sync
Map your SQL columns to Customer.io fields using Weld's visual mapper. Choose your sync mode — insert (create new records), update (modify existing), or upsert (create or update) — and set a schedule from every 5 minutes to daily.
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.
Technical considerations
Sync modes
Choose between insert, update, or upsert sync modes when pushing data to Customer.io. Upsert is recommended to avoid duplicates.
Rate limits
Weld respects Customer.io'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.
