How to authenticate an Azure EventGrid API Connection using a script? - azure

Question

I am creating an EventGrid API Connection using an ARM Template. It gets created successfully, however, i still have to authenticate it by hand via Azure Portal.
Here is my ARM Template:
"resources": [
{
"type": "Microsoft.Web/connections",
"apiVersion": "2016-06-01",
"name": "[parameters('azureEventGridConnectionAPIName')]",
"location": "[resourceGroup().location]",
"properties": {
"api": {
"id": "[concat(subscription().id, '/providers/Microsoft.Web/locations/', resourceGroup().location, '/managedApis/', 'azureeventgrid')]"
},
"displayName": "[parameters('azureEventGridConnectionAPIName')]"
},
"dependsOn": []
}
]
Am i missing something in the template that is responsible for authenticating the Connection right away?
Is there a way to authenticate that connection using for example Azure PowerShell so i can automate that process?

Yes, we could create a service principal authentication during deploy. Following is the demo code.
"resources": [
{
"type": "Microsoft.Web/connections",
"apiVersion": "2016-06-01",
"name": "[parameters('azureEventGridConnectionAPIName')]",
"location": "[resourceGroup().location]",
"properties": {
"api": {
"id": "[concat('/subscriptions/subscriptionId', '/providers/Microsoft.Web/locations/', 'eastasia', '/managedApis/', 'azureeventgrid')]"
},
"parameterValues": {
"token:clientId": "[parameters('clientId')]",
"token:clientSecret": "[parameters('clientSecret')]",
"token:TenantId": "[parameters('TenantId')]",
"token:grantType": "[parameters('grantType')]"
},
"displayName": "[parameters('azureEventGridConnectionAPIName')]"
},
"dependsOn": []
}
]
