# ListConnectionTypes
<a name="API_ListConnectionTypes"></a>

The `ListConnectionTypes` API provides a discovery mechanism to learn available connection types in AWS Glue. The response contains a list of connection types with high-level details of what is supported for each connection type, including both built-in connection types and custom connection types registered via `RegisterConnectionType`. The connection types listed are the set of supported options for the `ConnectionType` value in the `CreateConnection` API.
