Defining Azure Stream Analytics iot-hub input source through Powershell - json

Question

I'm trying to write a powershell script that creates a new streamAnalytics job in my azure portal account, with input source as iot-hub and output source as blob storage account.
To do so, I'm using AzureRM command new-streamAnalyticsJob, and json files.
my problem is: I have not seen any documentation or example for json file where the inputs source is iot-hub. only event-hub.
what are the parameters I need to give in the json file? can anyone display an example for json file with input source to streamAnalytics job as Iot-hub?

Answer 1

I got the answer eventually: the required field I had to add to the inputs Oliver posted earlier here is:
"endpoint":"messages/events"
I added it under Datasource Properties section, and it works fine!
Thanks Oliver

Answer 2

To come back on the error message you are seeing, to add to Olivier's sample you need a Property named endpoint which corresponds to the endpoint in IoT Hub. If you are looking for Telemetry messages this will be:
"endpoint": "messages/events"
This can be found in the schema for Azure ARM: https://github.com/Azure/azure-rest-api-specs/blob/current/specification/streamanalytics/resource-manager/Microsoft.StreamAnalytics/2016-03-01/examples/Input_Create_Stream_IoTHub_Avro.json
So to complete Olivier's example, when using API version '':
"Inputs": [
{
"Name": "Hub",
"Properties": {
"DataSource": {
"Properties": {
"consumerGroupName": "[variables('asaConsumerGroup')]",
"iotHubNamespace": "[parameters('iotHubName')]",
"sharedAccessPolicyKey": "[listkeys(variables('iotHubKeyResource'), variables('iotHubVersion')).primaryKey]",
"sharedAccessPolicyName": "[variables('iotHubKeyName')]",
"endpoint": "messages/events"
},
"Type": "Microsoft.Devices/IotHubs"
},
"Serialization": {
"Properties": {
"Encoding": "UTF8"
},
"Type": "Json"
},
"Type": "Stream"
}
}
],

That'd look like the following for the inputs part of the ASA resource:
"Inputs": [
{
"Name": "IoTHubStream",
"Properties": {
"DataSource": {
"Properties": {
"consumerGroupName": "[variables('CGName')]",
"iotHubNamespace": "[variables('iotHubName')]",
"sharedAccessPolicyKey": "[listkeys(variables('iotHubKeyResource'), variables('iotHubVersion')).primaryKey]",
"sharedAccessPolicyName": "[variables('iotHubKeyName')]"
},
"Type": "Microsoft.Devices/IotHubs"
},
"Serialization": {
"Properties": {
"Encoding": "UTF8"
},
"Type": "Json"
},
"Type": "Stream"
}
}
]
