Creating multi-tenant native mobile application and associated REST API

Hi All,

I have a native Android application which is already registered with a Azure AD B2C tenant, the REST API is registered to the same tenant as well.

But now, the requirements have changed and I also have to allow users in Azure Active Directory tenant to use same application and access same set of APIs that are registered under B2C tenant. My question is, Is there a way to avoid registering the application and the API in the Active Directory tenant all over again, or is there some way to expose these APIs to Active Directory users as well.

Thanks,

    I do not think it is possible to avoid the registration part. You can use custom policies in Azure AD B2C to allow users from multiple Azure AD tenants to sign in using Azure AD B2C but you need to register the application within the organizational Azure AD tenant. You can refer to the Microsoft documentation to achieve the same.
