# GatewayPlatform


The gateway's platform configuration. You can only specify one platform type in a gateway.

(Legacy only) For Greengrass V1 gateways, specify the `greengrass` parameter with a valid Greengrass group ARN.

For Greengrass V2 gateways, specify the `greengrassV2` parameter with a valid core device thing name. If creating a V3 gateway (`gatewayVersion=3`), you must also specify the `coreDeviceOperatingSystem`.

For Siemens Industrial Edge gateways, specify the `siemensIE` parameter with a valid IoT Core thing name.
