# Connectors

Flink CDC provides several source and sink connectors to interact with external
systems. You can use these connectors out-of-box, by adding released JARs to
your Flink CDC environment, and specifying the connector in your YAML pipeline
definition.

## Develop Your Own Connector

If provided connectors cannot fulfill your requirement, you can always develop
your own connector to get your external system involved in Flink CDC pipelines.
Check out [Flink CDC APIs]({{< ref "docs/developer-guide/understand-flink-cdc-api" >}})
to learn how to develop your own connectors.
