Prerequisites
- Ensure that you have a Vantage tenant identifier before configuring identities. To get a tenant identifier, click Configuration in ABBYY Vantage. The identifier is on the General tab.
- Create a Redirect URI to receive the authentication responses. The URI is:
https://<your-vantage-url>/auth2/Saml2/Acs - Create an application registration (see the instructions below). Registering your application establishes a trust relationship between your application and the External Identity Provider.
Creating the application
To create the application, follow these steps:Open the Azure Portal
Go to Azure Portal and sign in. In the pane on the left, select Azure Active Directory.
Open App registrations
In the pane on the right, select App registrations and click New registration.

Fill in the registration form
Specify the following:
- Name — a name for the application.
- Supported account types — select Accounts in this organizational directory only.
- Redirect URI — for each Vantage URL that should authenticate using this account, enter
https://<your-vantage-url>/auth2/Saml2/Acs.

Set up Azure Active Directory
To set up Azure Active Directory, follow these steps:Set the Application ID URI
In the Expose an API tab, set the Application ID URI. Due to Microsoft Entra identifier URI restrictions, use the format
api://<appId>, where appId is the Application ID from the app registration (for example, api://cccc3333-dddd-4444-eeee-5555ffff6666). Copy this value — you’ll need it when configuring the External Identity Provider in Vantage.Next steps
Once Azure AD is configured, connect it to your Vantage tenant. You’ll need the URL to the Federation metadata document you copied in the Set up section (step 2). For the Vantage-side setup, see Setting up an External Identity Provider for a tenant.Related topics
