I was recently informed that my scripts for the secure application model no longer worked. This is due to Microsoft updating the PartnerCenter module with some breaking changes. To make sure you can use the Secure App Model script I’ve made a new version below.

The changes in this script are in the way the access token is generated, Normally you’d get a Windows Authentication pop-up to allow consent. This is no longer possible with the PartnerCenter 2.0 module. This also requires us to add an extra return-URI to the Azure Application. To fix these issues, use the script below.

The script

<#
    .SYNOPSIS
        This script will create the require Azure AD application.
    .EXAMPLE
        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App"

        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App" -TenantId eb210c1e-b697-4c06-b4e3-8b104c226b9a

        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App" -TenantId tenant01.onmicrosoft.com
    .PARAMETER ConfigurePreconsent
        Flag indicating whether or not the Azure AD application should be configured for preconsent.
    .PARAMETER DisplayName
        Display name for the Azure AD application that will be created.
    .PARAMETER TenantId
        [OPTIONAL] The domain or tenant identifier for the Azure AD tenant that should be utilized to create the various resources.
