How to set up Amazon S3 to Salesforce in Weld.
Guided setup in 5 steps.
- Step 01
Connect your cloud data warehouse
Add Amazon S3 as a data source in Weld with connection credentials that grant read access. Credentials are stored encrypted and never logged.
- Step 02
Define your transformation
Write a SQL query or dbt model that selects and transforms the data you want to push to Salesforce. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Salesforce expects. You can preview results before activating.
- Step 03
Connect Salesforce
Authenticate Salesforce 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 Salesforce.
- Step 04
Map fields and configure sync
Map your SQL columns to Salesforce 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.
- 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.

What to expect.
ELT vs. reverse ETL: Amazon S3 and Salesforce
ELT (Extract, Load, Transform) moves data from Salesforce into Amazon S3 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 Amazon S3 and pushes it into Salesforce 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 Amazon S3 and Salesforce.
Salesforce to Amazon S3- Sync modes
- Choose between insert, update, or upsert sync modes when pushing data to Salesforce. Upsert is recommended to avoid duplicates.
- Rate limits
- Weld respects Salesforce'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.
