Create an Immersive Reader resource and configure Microsoft Entra authentication
This article explains how to create an Immersive Reader resource by using the provided script. This script also configures Microsoft Entra authentication. Each time an Immersive Reader resource is created, whether with this script or in the portal, it must be configured with Microsoft Entra permissions.
The script creates and configures all the necessary Immersive Reader and Microsoft Entra resources for you. However, you can also configure Microsoft Entra authentication for an existing Immersive Reader resource, if you already created one in the Azure portal. The script first looks for existing Immersive Reader and Microsoft Entra resources in your subscription, and creates them only if they don't already exist.
For some customers, it might be necessary to create multiple Immersive Reader resources, for development versus production, or perhaps for different regions where your service is deployed. For those cases, you can come back and use the script multiple times to create different Immersive Reader resources and get them configured with Microsoft Entra permissions.
Permissions
The listed Owner of your Azure subscription has all the required permissions to create an Immersive Reader resource and configure Microsoft Entra authentication.
If you aren't an owner, the following scope-specific permissions are required:
Contributor. You need to have at least a Contributor role associated with the Azure subscription:
Application Developer. You need to have at least an Application Developer role associated in Microsoft Entra ID:
For more information, see Microsoft Entra built-in roles.
Set up PowerShell resources
Start by opening the Azure Cloud Shell. Ensure that Cloud Shell is set to PowerShell in the upper-left hand dropdown or by typing
pwsh.Copy and paste the following code snippet into the shell.

Create-ImmersiveReaderResource, supplying the '<PARAMETER_VALUES>' placeholders with your own values as appropriate.Create-ImmersiveReaderResource -SubscriptionName '<SUBSCRIPTION_NAME>' -ResourceName '<RESOURCE_NAME>' -ResourceSubdomain '<RESOURCE_SUBDOMAIN>' -ResourceSKU '<RESOURCE_SKU>' -ResourceLocation '<RESOURCE_LOCATION>' -ResourceGroupName '<RESOURCE_GROUP_NAME>' -ResourceGroupLocation '<RESOURCE_GROUP_LOCATION>' -AADAppDisplayName '<MICROSOFT_ENTRA_DISPLAY_NAME>' -AADAppIdentifierUri '<MICROSOFT_ENTRA_IDENTIFIER_URI>' -AADAppClientSecretExpiration '<MICROSOFT_ENTRA_CLIENT_SECRET_EXPIRATION>'The full command looks something like the following. Here we put each parameter on its own line for clarity, so you can see the whole command. Do not copy or use this command as-is. Copy and use the command with your own values. This example has dummy values for the
<PARAMETER_VALUES>. Yours might be different, as you come up with your own names for these values.Create-ImmersiveReaderResource -SubscriptionName 'MyOrganizationSubscriptionName' -ResourceName 'MyOrganizationImmersiveReader' -ResourceSubdomain 'MyOrganizationImmersiveReader' -ResourceSKU 'S0' -ResourceLocation 'westus2' -ResourceGroupName 'MyResourceGroupName' -ResourceGroupLocation 'westus2' -AADAppDisplayName 'MyOrganizationImmersiveReaderAADApp' -AADAppIdentifierUri 'api://MyOrganizationImmersiveReaderAADApp' -AADAppClientSecretExpiration '2021-12-31'Parameter Comments SubscriptionName Name of the Azure subscription to use for your Immersive Reader resource. You must have a subscription in order to create a resource. ResourceName Must be alphanumeric, and can contain -, as long as the-isn't the first or last character. Length can't exceed 63 characters.ResourceSubdomain A custom subdomain is needed for your Immersive Reader resource. The subdomain is used by the SDK when calling the Immersive Reader service to launch the Reader. The subdomain must be globally unique. The subdomain must be alphanumeric, and can contain -, as long as the-isn't the first or last character. Length can't exceed 63 characters. This parameter is optional if the resource already exists.ResourceSKU Options: S0(Standard tier) orS1(Education/Nonprofit organizations). To learn more about each available SKU, visit our Azure AI services pricing page. This parameter is optional if the resource already exists.ResourceLocation Options: australiaeast,brazilsouth,canadacentral,centralindia,centralus,eastasia,eastus,eastus2,francecentral,germanywestcentral,japaneast,japanwest,jioindiawest,koreacentral,northcentralus,northeurope,norwayeast,southafricanorth,southcentralus,southeastasia,swedencentral,switzerlandnorth,switzerlandwest,uaenorth,uksouth,westcentralus,westeurope,westus,westus2,westus3. This parameter is optional if the resource already exists.ResourceGroupName Resources are created in resource groups within subscriptions. Supply the name of an existing resource group. If the resource group doesn't already exist, a new one with this name is created. ResourceGroupLocation If your resource group doesn't exist, you need to supply a location in which to create the group. To find a list of locations, run az account list-locations. Use the name property (without spaces) of the returned result. This parameter is optional if your resource group already exists.AADAppDisplayName The Microsoft Entra application display name. If an existing Microsoft Entra application isn't found, a new one with this name is created. This parameter is optional if the Microsoft Entra application already exists. AADAppIdentifierUri The URI for the Microsoft Entra application. If an existing Microsoft Entra application isn't found, a new one with this URI is created. For example, api://MyOrganizationImmersiveReaderAADApp. Here we're using the default Microsoft Entra URI scheme prefix ofapi://for compatibility with the Microsoft Entra policy of using verified domains.AADAppClientSecretExpiration The date or datetime after which your Microsoft Entra Application Client Secret (password) expires (for example, '2020-12-31T11:59:59+00:00' or '2020-12-31'). This function creates a client secret for you. To manage your Microsoft Entra application client secrets after you create this resource, visit the Azure portal and go to Home -> Microsoft Entra ID -> App Registrations -> (your app)
[AADAppDisplayName]-> Certificates and Secrets section -> Client Secrets section.
Copy the JSON output into a text file for later use. The output should look like the following.
{ "TenantId": "...", "ClientId": "...", "ClientSecret": "...", "Subdomain": "..." }
