# Connectors

> Connect to file sources including S3 buckets and direct URLs

Connectors describe the source of your files. Each job uses exactly one connector. The connector produces one or more inputs and provides a stable identifier for each input (for example, an S3 object key or a URL). That identifier is echoed back in responses so you can map results to the original files.
