Sample for integrating External Identities self-service sign-up with experian identity verification using API connectors

Experian External Identities self-service sign-up API connector integration

Azure Active Directory (Azure AD) External Identities enable you to provide self-service sign-up for external users so that collaboration is seamless and end-user friendly. API connectors enable you to leverage web APIs to integrate those self-service sign-up flows with external cloud systems.

Verifying a user's identity can be critical to securing an application from fraudulent and malicious actors and confidently allowing self-service sign-up. To accomplish this, you can use Experian's identity services including continuous and dynamic authentication, fraud risk analytics and identity verification capabilities through the Experian CrossCore platform.

This integration asks the external user multiple details using a self-service sign-up and uses Experian to determine whether the user should be allowed to successfully sign-up or not. The following attributes are used in making a pass/fail decision:

  • Given Name
  • MiddleName
  • Surname
  • Street Address
  • City
  • State/Province
  • Postal Code
  • Country/Region
  • PhoneNumber


File/folder Description
/CrossCoreExtIdApi Sample source code for custom web API.

You must have an Azure Active Directory tenant.

Solution Components

The Experian integration is comprised of the following components:

  • Experian -- A service that can be used to verify a user's identity using information provided by the user.
  • Azure AD External Identities self-service sign-up - The way to allow external customers to sign-up as external users to your organization.
  • Custom web API -- The provided API implements the integration between the Azure AD self-service sign-up user flow and the Experian service to perform identity verification on sign-up.
  • API connector - Part of a self-service sign-up, allows you to connect the sign-up flow with the custom web API.

Create an Experian account

When you are ready to get an Experian account, sign up using this web form.

Deploy the API

Deploy the provided API code to an Azure service. The code can be published from Visual Studio, following these instructions.

Note the URL of the deployed service. This will be needed to configure the API connector with the required settings.

Configure the API

Application settings can be configured in the App service in Azure. This allows for settings to be securely configured without checking them into a repository. The API needs the following settings provided:

Application Setting Name Source
CrossCore:TenantId Experian account configuration
CrossCore:OrgCode Experian account configuration
CrossCore:ApiEndpoint Experian account configuration
CrossCore:ClientReference Experian account configuration
CrossCore:ModelCode Experian account configuration
CrossCore:HdrRequestType Experian account configuration
CrossCore:OrgCode Experian account configuration
CrossCore:SignatureKey Experian account configuration
CrossCore:TenantId Experian account configuration
CrossCore:CertificateThumbprint Experian certificate
BasicAuth:ApiUsername Set a username for accessing the API.
BasicAuth:ApiPassword Set a password for accessing the API.

Integrate the API with External Identities self-service sign-up

Azure AD needs to be configured for use with external identities.

Configure a self-service sign-up user flow

Create a self-service sign-up user flow for registering external users to your tenant.

Before you create the user flow, create the custom attributes that Experian uses to to verify an identity:

  • MiddleName
  • PhoneNumber

When creating the user flow, the following must be selected under *User Attributes in order to collect the relevant information from the user:

  • PhoneNumber
  • MiddleName
  • Given Name
  • Postal Code
  • Street Address
  • State/Province
  • Surname
  • City
  • Country/Region

Create an API Connector

After the Azure AD tenant has been configured for use with External Identities self-service sign-up, create an API connector

  • Display Name: Choose a name such as 'Verify identity with Experian'.
  • Endpoint URL: Use the URL created when publishing the API service.
  • Username: Username defined in the API configuration above (BasicAuth:ApiUsername)
  • Password: Password defined in the API configuration above (BasicAuth:ApiPassword)

Enable the API connector in the user flow

Enable the API connector for the user flow. Navigate to User flows (Preview), click the user flow you created, and click on API connectors. From here, click on the drop-down menu for Before creating the user and select the API connector (e.g. 'Verify identity with Experian').

End user experience

Your self-service sign-up user flow should now be calling the API when a user signs up. The API uses the Experian service to verify an account. If the user cannot be verified, the user will be shown an error message and asked to review their personal information.
