    Using the Azure API Management REST API as workaround to RBAC functionality


    If you are using Azure API Management today, you might have noticed the service is only available in the previous Azure management portal. While support in the newly GA’s portal is coming, this does mean that one of the features that the new portal exposes, namely Role Based Access Control (RBAC) is not yet available.
    While working on a recent API Management implementation at a customer, they were looking to activate RBAC so that their admin users for the API Management service would not require any admin rights on the Azure portal itself. API Management contains a concept of Publisher Portal, which is where the admins do their work of customizing the exposed APIs.
    First reaction was to explain to the customer that they would have to wait for this feature to become available. But after a discussion with my colleagues in the product team, they explained a workaround that would enable me to help the customer right away. It just requires leveraging the REST API and a little coding to get the job done.
    Azure API Management has a REST API to do administrative tasks. This API exposes things like the Tenant, Users and Groups, Products, Reports and more. It is there to help you automate parts of your API Management tenant configuration and working. One of the entities that are exposed through the REST API is a User. Within this entity, there is one very interesting method to help us with our problem, namely generateSsoUrl.

    Let’s review that. According to the documentation:

    This operation retrieves a redirection URL containing an authentication token for signing a given user into the developer portal.

    The above actually also applies to the Publisher portal, which can use the same access token, however the user for which you need the token needs to be an admin user. This is done by leveraging the User ID 1. The API Management setup this concept of user 1 being the admin, because they wanted something simple to bridge between now and the moment RABC will be baked in. So, exactly what we need!

    Setting up our RBAC workaround

    Here’s the tasks we will execute to get this working:
    1. Configure Azure API management account to enable the REST API and setup the access token.
    2. Setup a development environment with Visual Studio 2015 and Azure SDK 2.8.
    3. You need Admin access to your Azure subscription, and make sure you have service administrator level to the Azure AD domain you want to use.
    4. Create a web app (ASP.NET) that validates whether the current user is member of a pre-defined Azure AD group. If yes: generate a Login link with an access token to the Azure API Management account.
    5. Deploy the application to Azure, to an App Service Web App.
    6. Leverage or create a custom Azure AD group to hold the members with Admin rights to the Azure API management account.
    7. Setup Authorization/Authentication feature in the Azure Web App to validate the user.

    Configure Azure API Management account

    In this portion, we assume you already have an account created. Go to the publisher portal of your account, browse to Security and activate Enable API Management REST API checkbox. Wait for a confirmation the action is successful.

    Now configure and make a note of the access token. Scroll to the bottom of the page and configure an expiry date for your token. For testing, choose at least a date later than today. This token can later be changed, just make sure it is then copied to the App settings if that happens.

     Write down the SharedAccessSignature as we’ll need it later. You won’t be able to see it once you leave this page.

    Azure AD: Retrieving the right Group ID

    This step can also be done at the end, but if you want to have more settings automated through the ARM resource deployment, then get the ID for your group before creating the first deployment.
    Navigate to your Azure AD using the Azure Management Portal, click Groups. Go to the Configure tab and copy the Object ID. You will need this ID in the deployment step. If you skipped this step in Visual Studio, you can still edit its value through the Web App’s Application Settings pane.


    For this setup to function, you need to make sure your test users are actually members of the Group above.

    Creating the ASP.NET Web app

    We’ll use ASP.NET app with just one page that shows a login box for entitled users, and a default message for those that are not. You can review the sample code in this GitHub repo.

    Nothing of a sophisticated web app, just something to get the point across in this post.

    A few elements relevant to review:


    public class HomeController : Controller

    We leverage the Authorize attribute to make sure the page does not process without the user being authenticated.

    Next, a utility class is used to interact with the API Management REST API, and use the generateSsoUrl action.


    requestUrl = string.Format("{0}/users/{1}/generateSsoUrl?api-version={2}", baseUrl, "1", API_VERSION);

    using (HttpClient httpClient = newHttpClient())


                   var request = new HttpRequestMessage(HttpMethod.Post, requestUrl);

                    request.Headers.Authorization = new AuthenticationHeaderValue("SharedAccessSignature", sharedAccessSignature);

            HttpResponseMessage response = await httpClient.SendAsync(request);


                   string responseBody = await response.Content.ReadAsStringAsync();

    return responseBody;


    We leverage the Authorize attribute to make sure the page does not process without the user being authenticated.

    Next, a utility class is used to interact with the API Management REST API, and use the generateSsoUrl action.

    publicActionResult Index()


         var claimsPrincipal = Thread.CurrentPrincipal asClaimsPrincipal;

                ViewBag.HasAccess = false;

               if (claimsPrincipal != null)


                   Claim groupApimAdmin = claimsPrincipal.Claims.FirstOrDefault(

                    c => c.Type == "groups" &&  c.Value.Equals(groupToValidate, StringComparison.CurrentCultureIgnoreCase));

                   if (null != groupApimAdmin)


                        ViewBag.HasAccess = true;



               return View();


    Deploying the app to Azure

    We’ve also created a Cloud Deployment project in Visual Studio to help us with the deployment of the application to Azure. The Cloud Deployment project uses Azure Resource Management JSON template to create the web app, an App Service Plan and set the Application Settings we require for our app to function.

    Note: Before deploying though, make sure you have a Storage account created through the portal, as the Cloud Deployment Project requires this to temporarily copy the deployment contents.
    This needs to be a Storage account using the Resource Manager deployment type – see more here

    In the Visual Studio project, the Cloud Deployment project already has a reference to the web application, this will build and generate a webdeploy package.

    The JSON parameters can be entered through the Visual Studio interface, then click Save and Deploy to initialize the deployment to Azure.

    - webSiteName – the name of the website that will host the webapp  - needs to be unique on Azure (so not just for your subscription)
    - hostingPlanName – new app service plan name, unique only for your Azure account.
    - apimTenantName – the name of the APIM account
    - apimAdGroupId – GUID corresponding to the group to which the internal Admin users must belong to in order to get access to the Azure API Management publisher portal. See above for details on retrieving the right Group ID.
    - apimSas – this is a secure string that needs to contain the ShareAccessSignature you created above. Only copy the part after ShareAccessSignature and remove the space. It should start with uid=…
    - ApimDeployPackageFolder: The name of the app in Visual Studio
    - ApimDeployPackageFileName: (use this name)

    Review the Output window to validate the progress and successful completion of the ARM deployment.

    Securing the Web App

    The Azure web application uses Authorization/Authentication feature in Azure App Service to secure the application itself. Once the user is allowed in through Azure AD authentication, it then validates the user is part of the predefined Group (claim). If valid, the Azure API Management REST API is used to generate a valid Admin User token. With this valid token the redirection to the Publisher portal is then initiated.

    To set this up, go to your newly deployed Web App in the new Azure Portal. When browsing to the web app, you should see something like this.

    This is because we have used the [Authorize] attribute in the Controller, so that the web app is not accessible at all without the proper Authorization setup in Azure.

    In the Azure portal, browse to the newly created web app, then click Authentication/Authorization.

    Choose On to activate the feature. Next choose “Login with Azure Active Directory” in the Action to take when request is not authenticated. Then continue by configuring Azure AD, click Not Configured to open the details pane.

    Choose Express settings, provide a unique name to the app. This will create and configure the unique App in Azure AD.

    Note if you prefer to setup another Azure AD domain or app settings, you can manually configure the right app in Azure AD and choose the Advanced pane to just enter the app’s ID and secret.

    For this test we just choose the simple Express version. Click OK, then back in the main Authorization pane, click the Save button. You can now close the Authentication/Authorization pane.

    Configure Azure AD app settings

    With the above configuration, a new Azure AD application has been added. We still need to configure a few things. Browse to the (old) Azure Management portal and open up your Azure AD domain details.
    Choose Applications tab, then select Applications my company owns, and click the search button (v). The newly created app should be in the list. Click on it to open it. Go to the app’s Configure tab and click Delegated Permissions, activate Read directory data, and then click SAVE.

    Next, after successfully saving, the bottom bar should now display a button “Manage Manifest”. In that action, choose Download manifest. Save it locally and open it up in a code editor. For more information about the Azure AD manifest, see here
    Edit your manifest and change “groupMembershipClaims” value to “SecurityGroup” instead of the value null.


    Save the manifest.

    Back in the Azure portal, in your Azure AD application were editing previously, click the Manage Manifest button again, this time choose Upload Manifest.
    See the following article for a detailed overview of authorization with AD group claims:

    Validating the solution

    Before testing if the solution works, make sure the App Settings have been updated with the different values:


    With all the settings configured, browse to the Web App again. Instead of receiving the error message, you should see a redirection to Azure AD authentication. If you are using the same browsing window as your Azure user, you will be redirected automatically as you are already authenticated. Now click the LOGIN button and you should have access to the Publisher portal for API Management.

    To test correctly, I advise creating a new test user in Azure AD, assigning the user to the above group, and activating the user. Testing the application with the newly created user should work end to end.

    Possible issues

    - Token is not valid – to see the actual error message you can activate Stream logs
    - Token has expired: generate a new one and update the Web App’s app setting.
    - Group claims does not return the required Group – you might see a detail in getting the newly assigned group of an AD user, this might seem like an error but I assume there is a cache that needs to expire so that new group memberships get returned with in the claims.

    Security concerns: the access token is stored in the App Settings pane, which is accessible by Azure admins. Knowing the same admins also have access to the portal to generate a new token we don’t think this is a big risk. You can evaluate storing the token in Key Vault and retrieving it from there.

    Azure API Management - Using PowerShell for backup and restore


    Automation is the new Black, as "said" by Mark Russinovich during AzureCon.

    One of the ways to automate in Azure is by using PowerShell tools for Azure, next to other options. I've been working with Azure API Management for some customers lately, and one interesting short post caught my attention: Full set of Windows PowerShell cmdlets for Azure API Management API. This means that now a number of functions to manage API Management have been made available as PowerShell cmdlets, making it easy to use in automation tasks.
    Backup and restore is one of the features I’ve been using. While its primary use is for having a backup of your current API Management account, for example making sure this is done very regularly as a way to recover in the event of failure. Another use for the backup/restore feature is when going from development to a staging environment.
    Official documentation for doing backup/restore shows us how to do this using the Azure Resource Manager based API Management REST API. But it also requires creating an Azure AD application, setting the right permissions and getting a token for authenticating requests to Azure Resource Manager. Stuart Leeks has an interesting blog post with an alternative non-supported way to use PowerShell, and now with the official cmdlets this is exactly what we can do.

    So why not give that a try?

    Creating a backup requires the following information: your API Management account, the resource group name and a storage account to which to save the backup to as well as the container in which it will go.

    Prepare for the backup

    1. Make sure you have configured PowerShell and connected to your subscription.

    2. Connect to the storage account and make sure to create the container to which you will store your backup to. Note the name. You can do this through the Azure Management Portal, or using a Storage explorer tool. Also take note of the type of Storage that you are using. There are currently two types, one used in the current Management Portal, and the new mode using Azure Resource Manager.

    3. Identify the name of the Resource Group in which your API Management account is created: use to navigate to the subscription. The resource group name has automatically been created, and is in the form of 'Api-Default-{service-region}'.
    Run backup

    Create a Storage Context.

     if ($ARMStorage)
      Switch-AzureMode AzureResourceManager
         $StorageAccountKey = (Get-AzureStorageAccountKey -ResourceGroupName $StorageAccountResourceGroupName -Name $StorageAccountName).Key1
      Switch-AzureMode AzureServiceManagement
         $StorageAccountKey = (Get-AzureStorageKey -StorageAccountName $StorageAccountName).Primary

    $StorageAccountContext = New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey

    Run backup

    Switch-AzureMode AzureResourceManager

    Backup-AzureApiManagement -Name "myAPIMaccount" -ResourceGroupName "Api-Default-West-Europe" -StorageContext $StorageAccountContext `
                           -TargetContainerName "mycontainer" `
                           -TargetBlobName "myapimbackupddmmyy"

    Typically you’d create variables for the above values, but for testing we can hard-code them.
    For automating the backup you can use something like Azure Automation, currently you’ll need some manual work to support Azure Resource Manager though.

    Run restore

    To run a restore, simply run the following command.

    Restore-AzureApiManagement -Name "myAPIMaccount" -ResourceGroupName "Api-Default-West-Europe" `
                            -StorageContext $StorageAccountContext `
                            -SourceContainerName "mycontainer" `
                            -SourceBlobName "myapimbackupddmmyy" -Verbose

    Do read through the notes on the official documentation to understand some of the constraints, including the fact that a restore is only guaranteed maximum 7 days after backup.

    Windows Azure Infrastructure as a Service General Availability



    Microsoft just announced the general availability of our Windows Azure Infrastructure as a Service (IaaS) support! With this release Azure Virtual Machines and Virtual Network move out of Preview and are now ready to use for your production apps.

    With Azure Virtual Machines you can deploy and run durable VMs in the cloud, provisioned from prebuilt templates or alternatively upload your own custom-built VMs.  All this in a matter of seconds!  Azure Virtual Network allows you to securely bridge between your on-premises infrastructure and your infrastructure in the cloud. This gives you the flexibility to run your workloads where you want, but manage them all in the same way.

    Whether you want to securely extend your on-premises network to Windows Azure or you want to create a virtual private network with persistent private IPs..

    Let’s look in more detail into what we have announced today:

    • For memory intensive scenarios, we are now introducing two high-memory compute instances: 4 core x 28GB RAM and 8 core x 56GB RAM. With these VM sizes you can run even larger workloads on Windows Azure, for example SharePoint Server or SQL Server workloads.
    • We have added several new VM image templates to the Image Gallery, such as SQL Server 2012, BizTalk Server 2013 and SharePoint Server 2013 images. These images also come with hourly billing, so you don’t have to pay for an upfront license.
    • We have updated the SLA for Virtual Machines and Virtual Network.  For VMs that have 2 or more instances deployed in the same availability set, we have a 99.95% SLA for external connectivity.  For Virtual Network, we guarantee a 99.9% Virtual Network Gateway availability.
    • As of this announcement, Virtual Machines and Virtual Network are now supported by Microsoft Support staff, so you can confidently run your production apps on Azure.


    On top of all these great features, we’re also announcing significant pricing reductions to our Windows Azure PaaS and IaaS VM pricing. You can expect to see from 20% (Virtual Machines) to 33% (Cloud Services) price reductions! These new prices are effective as of June 1.  And as of today, we’re also adding 50 hours of free memory-intensive-instance hours to our member offers and 90-day trials.

    For a more detailed description of the announcement, you can check out Scott Guthrie’s blog post.

    If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Did you know that you already have a lot of free Azure resources as part of your MSDN, MPN or BizSpark membership? 

    If you want to learn more about our Windows Azure IaaS capabilities, don’t forget to listen in on our dedicated IaaS webcast on April 30. If you want to experience this great technology hands-on, join us for our Azure IT Camp on May 6.

    Windows App Day – slides and video from the event


    A small month ago on November 23rd we welcomed over 200 attendees to our first Windows App Day in Antwerp, focusing on developer and User Experience/web content for building apps. What types of apps you ask? A lot of it was centered around Windows 8 Store apps but also Windows Azure and mobile services as well as Windows Phone 8 Platform.

    We kicked off by an opening session with Luc Van de Velde, director of our Developer Platform team; followed by the presentation of several cases. I would like to thank our partners for being on stage with us:

    1. Alain from Nascom with the Bumba Windows 8 app. App was built in HTML5 using CreateJS, you can read about the migration from iOS game experience here.
    2. Persgroep with the apps for De Morgen, Het Laatste Nieuws and others;
    3. Brecht Kets from Howest University on the student games created using MonoGame
    4. Johan Peeters on his experiences with Windows Phone development and the Belgian Apps app. Note: Johan is currently working on the “Belgian Apps” for Windows 8 too. If you are interested in beta testing contact him through Twitter.
    5. Twipe Mobile on their digital newspaper platform partly based on Windows Azure, and presenting the case for the Windows 8 app for “De Standaard’.

    A big thanks to my colleagues too for joining me on delivering a team keynote. We all had lots of fun presenting it.

    The content, videos and speakers

    Looking at the session evaluations and by talking to many of the attendees, we know folks especially appreciated some of the less typical sessions, that is: the UX guidance for Windows Store apps. For example, Bart Claeys’ session on migrating an iOS app to Windows Store was hugely popular.

    The good news: you’ll find the sessions slides below, and available at the MSDN Belux SlideShare.


    Even more: most video recordings of the sessions are now also online on Channel9. Do note that some of the coding sessions’ recording quality is not what we would consider optimal. We still chose to publish them as it might be interesting for folks that want to review something they missed in a session.

    Cloudify your Windows 8 and iOS apps with Windows Azure Mobile Services


    Leveraging my colleague Nick’s post on Windows Azure Mobile Services here. WAMS has received an upgrade, now supporting iOS next to Windows 8, and including new authentication support, sending e-mails, SMS en more.
    If you are from Belgium or Luxembourg, and are thinking about leveraging WAMS for your Windows 8 or iOS apps please let us know. We’d like to hear about your experiences.


    With the introduction of apps and application stores, the process of building, selling and distributing software has been truly democratized.  But what if your application becomes a top hit and is being downloaded and used by millions of users?  How do you make sure that your backend services scales dynamically with this unpredictable demand?

    Windows Azure Mobile Services makes it incredibly easy to connect a scalable cloud backend to your client and mobile applications.  It allows you to easily store structured data in the cloud that can span both devices and users, integrate it with user authentication, as well as send out updates to clients via push notifications.


    Windows Azure Mobile ServicesA couple of weeks ago we announced Windows Azure Mobile Services with support for Windows 8 apps. This week we delivered initial support for connecting iOS based devices (including iPhones and iPads) to Windows Azure Mobile Services.  We’ll also be adding support to enable these same scenarios for Windows Phone, and Android devices soon.


    In addition, we have also released the following great improvements to Windows Azure Mobile Services:

    • Facebook, Twitter and Google authentication support
    • Sending emails from your Mobile Service, in partnership with SendGrid
    • Sending SMS messages from your Mobile Service, in partnership with Twilio
    • Support for connecting to Azure Storage and Azure Service Bus


    Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple iOS “Todo List” app that stores data in Windows Azure.  Then follow the below tutorials to explore how to use the iOS client libraries to store data and authenticate users.


    image If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services.
