Automate app registration in B2C

Question

Hi,

I wanted to know if there is any documentation or code sample to describe how to automate app registration in Azure AD B2C. I want to register app through script or any other way, which I can attach with devops pipeline and automate whole process?

Thanks,
Vikas Tiwari

You can use MS Graph Create Application operation and other supported. Follows sample request:

   {  
     "displayName": "NewAppFromMSGraph",  
     "requiredResourceAccess": [  
       {  
         "resourceAppId": "00000003-0000-0000-c000-000000000000",  
         "resourceAccess": [  
           {  
             "id": "37f7f235-527c-4136-accd-4a02d197296e",  
             "type": "Scope"  
           },  
           {  
             "id": "7427e0e9-2fba-42fe-b0c0-848c9e6a8182",  
             "type": "Scope"  
           }  
         ]  
       }  
     ],  
     "signInAudience": "AzureADandPersonalMicrosoftAccount",  
     "web": {  
       "implicitGrantSettings": {  
         "enableIdTokenIssuance": true,  
         "enableAccessTokenIssuance": true  
       },  
       "redirectUris": [  
         "https://jwt.ms"  
       ]  
     }  
   }

Thanks for sharing the details.
So if I create simple console app and run following code it should create (register) app into my b2c tenant.

IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
            .Create(clientId)
            .Build();

Func<DeviceCodeResult, Task> deviceCodeReadyCallback = async dcr => await Console.Out.WriteLineAsync(dcr.Message);
DeviceCodeProvider authProvider = new DeviceCodeProvider(publicClientApplication, scopes, deviceCodeReadyCallback);

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var application = new Application
{
    DisplayName = "Display name"
};
    await graphClient.Applications
    .Request()
    .AddAsync(application);

What is Client id here (I guess its application id) but I dont have any application in my tenant directory yet and I trying to register, how can I pass client id?

Am I missing any thing here?

Hi,

I have found a way to create app in azure B2C tenant using cli, following are the commands helped me to create app in B2C tenant:

az login -t myb2ctenant.onmicrosoft.com --allow-no-subscriptions (this cmd helped me to login to B2C without subscription)

az ad app create --display-name testb2capp (this creates app in B2C)

az ad app list --display-name testb2capp (Gives details of newly created app)

az ad app update --id APP_ID_FROM_ABOVE_CMD --reply-urls https://jwt.ms (update any values in app)
