Microsoft Graph Domains

Microsoft Graph Domains is the set of Microsoft Graph APIs and resources for discovering and managing your organizations domain names in Microsoft Entra ID (Azure AD). It lets you list all domains in a tenant and read key properties (for example, whether a domain is verified, default, initial, root, or which services it supports), add new custom domains, retrieve the DNS records needed for ownership verification, and complete the verification process. You can also manage authentication settings (managed or federated), work with federation configurations for SSO, and delete domains when theyre no longer referenced. These capabilities enable automation for tenant provisioning, domain onboarding and migration, and consistent domain governance across Microsoft 365 services.
