powershell - How to add application to Azure AD programmatically?

Question

I want to automate the creation of my application in Azure AD and get back the client id generated by Azure AD.

Are there PowerShell commandlets to do this? Is there some other means, like an API of doing this besides the management console?

Can you point me to an example?

Thanks!

There are a number of ways you can create an application in AAD Programatically. I will briefly cover two different ways you can go about doing this: PowerShell CMDLETs and the Graph API. In general, I would strongly reccommend using the Graph API for this.

PowerShell:

There are a few different modules running around that have the ability to create AAD Applications/Service Principals. If you need to create a new application object in your tenant, you can use Azure PowerShell to make the following call:

https://msdn.microsoft.com/en-us/library/mt603747.aspx

PS C:> New-AzureRmADApplication -DisplayName "NewApplication" -HomePage "http://www.Contoso.com" -IdentifierUris "http://NewApplication"

If you need to create a service principal for your application in your tenant you can use Azure AD PowerShell:

https://msdn.microsoft.com/en-us/library/azure/jj151815.aspx

https://msdn.microsoft.com/en-us/library/azure/dn194119.aspx

New-MsolServicePrincipal -ServicePrincipalNames @("MyApp/Contoso.com") -DisplayName "My Application"

Graph API: (recommended)

You can also create applications by making a POST to our Graph API: https://msdn.microsoft.com/Library/Azure/Ad/Graph/api/entity-and-complex-type-reference#ApplicationEntity

We have samples that show how you can register and create an applicatoin to target the Graph API, and use the Graph Client Library to assist you in making the correct calls to the API:

I hope this helps!
