Is automating App Registration on Azure possible through ARM Template on the User's tenant?

Question

I am trying to deploy a solution as a managed application through ARM Template. For the deployment to work, I need the Client Id and Client Secret of a registered Application along with the Tenant Id.

In my previous scope, I was assuming that the user would have an existing App Registered but now I want to Automate the App registration process for the user and be able to register an application having O365 API Permissions in user's tenant.

Below is the approach I were following earlier.

So unlike above approach, I am now trying to create either a Web Application or a Function Application which would authenticate the User and register the Application for them.

Answer 1

No, it's impossible.

ARM Template is used to create Azure resources under Azure subscription. But App Registration is the resource of Azure AD module. They are two different areas.

A similar discussion here for your reference.

You can use Azure AD Powershell to create the Azure AD app and create the client secret by using New-AzureADApplication and New-AzureADApplicationPasswordCredential .

Answer 2

I'm facing a similar problem and seems that ARM deployment scripts may be the answer:

this post gives an example on how to create app registrations with ARM deployment scripts:
