How to get certificate for Azure Automation Client - asp.net-mvc

Question

I need to create automaion client for Azure webhook.
Following code is written by me to get AutomationManagementClient Value.
var cert = new X509Certificate2(Convert.FromBase64String(ConfigurationManager.AppSettings["CertBase64String"]));
var creds[![enter image description here][1]][1] = new CertificateCloudCredentials(ConfigurationManager.AppSettings["SubscriptionId"], cert);
AutomationManagementClient automationManagementClient = new AutomationManagementClient(creds);
I need that certificate string i.e. CertBase64String value as I don't know from where I will get that value.
Help me...
This error I am getting after updating as per your answer.

If you want to create the automation client, I suggest you try to use the ARM way to operate the automation. The following is the demo code works correctly on my side.
Prepare: Registry an AD application and assign role to applcation, more details please refer to Azure official tutorials. After that we can get tenantId, appId, secretKey from the Azure Portal.
We could use the following code to get the token
var tenantId = "tenantId";
var context = new AuthenticationContext($"https://login.windows.net/{tenantId}");
var clientId = "application Id";
var clientSecret = "client secret";
var resourceGroup = "resource group";
var automationAccount = "automationAccount";
var subscriptionId = "susbscriptionId";
var token = context.AcquireTokenAsync(
"https://management.azure.com/",
new ClientCredential(clientId, clientSecret)).Result.AccessToken;
if you use the Microsoft.Azure.Management.Automation Version <= 2.0.4 please try the following code.
var automationClient = new AutomationManagementClient(new TokenCloudCredentials(subscriptionId,token));
var webhook = automationClient.Webhooks.CreateOrUpdate(resourceGroup, automationAccount,new WebhookCreateOrUpdateParameters
{
Properties = new WebhookCreateOrUpdateProperties
{
ExpiryTime = DateTimeOffset.Now.AddDays(1),
IsEnabled = false,
Parameters = parameters,
Runbook = new RunbookAssociationProperty
{
Name = "xxxx"
},
Name = "xxxx",
Uri = "https://xxxx.xx"
}
});
if use the Microsoft.Azure.Management.Automation Version 3.0.0-preview, please try to the following case.
var automationClient = new AutomationClient(new TokenCredentials(token)) {SubscriptionId = subscriptionId};
var webhook = automationClient.Webhook.CreateOrUpdate(resourceGroup, automationAccount, "webhookName",
new WebhookCreateOrUpdateParameters
{
ExpiryTime = DateTime.Now.AddDays(1),
IsEnabled = false,
Parameters = parameters,
Name = "xxxxx",
Runbook = new RunbookAssociationProperty
{
Name = "xxxxx"
},
Uri = "https://xxx.xxx"
});
Update:
You could set the Parameters = null or if you have parameter, you could define the parameters as dictionary. Please also add the Name = "xxxx" in the code.
var parameters = new Dictionary<string, string> {{"test", "test"}};
var webhook = automationClient.Webhooks.CreateOrUpdate(resourceGroup, automationAccount,new WebhookCreateOrUpdateParameters
{
Properties = new WebhookCreateOrUpdateProperties
{
ExpiryTime = DateTimeOffset.Now.AddDays(1),
IsEnabled = false,
Parameters = parameters,
Runbook = new RunbookAssociationProperty
{
Name = "xxxx"
},
Name = "xxxx",
Uri = "https://xxxx.xx"
}
});
I test it on my side, it works correctly

"CertBase64String" will get by passing thumb-print of that certificate to following fucntion.
internal static X509Certificate2 GetCertificateFromthumbPrint(String certThumbPrint) {
X509Store certStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);
certStore.Open(OpenFlags.ReadOnly);
//Find the certificate that matches the thumbprint.
X509Certificate2Collection certCollection = certStore.Certificates.Find(X509FindType.FindByThumbprint, certThumbPrint, false);
certStore.Close();
//Get the first cert with the thumbprint
X509Certificate2 cert = (certCollection.Count > 0) ? certCollection[0] : null;
return cert;
}
