# GET /20200301/gateways/{gatewayId}/capability/{capabilityNamespace}

`GET /20200301/gateways/{gatewayId}/capability/{capabilityNamespace}`

Retrieves information about a gateway capability configuration. Each gateway capability defines data sources for a gateway. A capability configuration can contain multiple data source configurations. If you define OPC-UA sources for a gateway in the IoT SiteWise console, all of your OPC-UA sources are stored in one capability configuration. To list all capability configurations for a gateway, use <a href="https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_DescribeGateway.html">DescribeGateway</a>.
