Connectors

A connector is how Weld reads from a tool or database, and for many tools also writes back to it with reverse ETL. You connect an account once, then use the connection in as many syncs as you need. See Data sources (ELT) for how syncs work.

Weld has over 300 connectors. Each one has a setup guide here, which also opens beside the form when you add the data source in Weld:

• Applications: SaaS tools such as HubSpot, Shopify, Google Ads and NetSuite.
• Databases: PostgreSQL, MySQL, SQL Server and MongoDB, with Change Data Capture.
• Data warehouses: BigQuery, Snowflake and MotherDuck as sources.
• Files: spreadsheets and files from Google Sheets, Excel, S3, SFTP and more.
• Functions and Custom connector: sync from any API with code you write.
