Error while updating location of the azure api management service

I'm trying to update the region of the created azure management api service instance using the rest api.

URL - https://management.azure.com/subscriptions/b0474e6c-9d1c-4b84-87f5-27ef6aad5e5e/resourceGroups/res1/providers/Microsoft.ApiManagement/service/cloud1?api-version=2017-03-01

Body

{ "parameters": { "serviceName": "cloud1", "resourceGroupName": "res1", "api-version": "2017-03-01", "subscriptionId": "b0474e6c-9d1c-4b84-87f5-27ef6aad5e5e", "parameters": { "location": "North Central US" } }, "responses": { "200": { "id": "/subscriptions/b0474e6c-9d1c-4b84-87f5-27ef6aad5e5e/resourceGroups/res1/providers/Microsoft.ApiManagement/service/cloud1", "name": "", "type": "Microsoft.ApiManagement/service", "tags": {}, "location": "Central US", "etag": "AAAAAACYO/A=", "properties": { "publisherEmail": "", "publisherName": "", "notificationSenderEmail": "[email protected]", "provisioningState": "Succeeded", "targetProvisioningState": "", "createdAtUtc": "2017-02-14T04:33:06.0312071Z", "gatewayUrl": "https://cloud1.azure-api.net", "portalUrl": "https://cloud1.portal.azure-api.net", "managementApiUrl": "https://cloud1.management.azure-api.net", "scmUrl": "https://cloud1.scm.azure-api.net", "hostnameConfigurations": [], "staticIps": [ "40.66.160.152" ], "additionalLocations": null, "virtualNetworkConfiguration": null, "customProperties": null, "virtualNetworkType": "None" }, "sku": { "name": "Developer", "capacity": 1 } } } } 

Headers

Authorization Bearer Content-Type application/json

I'm getting below error.

{ "error": { "code": "InvalidRequestContent", "message": "The request content was invalid and could not be deserialized: 'Could not find member 'parameters' on object of type 'ResourceDefinition'. Path 'parameters', line 2, position 15.'." } } 

Am I doing anything wrong??
