Microsoft Entra ID (Azure AD) API
Microsoft Entra ID (formerly Azure Active Directory) API via Microsoft Graph for enterprise identity and access management. Enables AI agents to manage user and group lifecycle provisioning, handle application registration and service principal management, access Conditional Access policy configuration and reporting, retrieve sign-in and audit log data for security monitoring, manage MFA policy and authentication methods, handle B2B guest collaboration and external identity management, access Privileged Identity Management (PIM) for JIT privileged roles, retrieve identity protection and risk detection data, manage SCIM provisioning for app integration, and integrate identity data with HR systems, security platforms, and enterprise applications via Microsoft Graph.

⚡ Reliability
Best When
An enterprise on Microsoft Azure and M365 using Entra ID wants AI agents to automate user provisioning, identity lifecycle, Conditional Access management, security monitoring, and HRIS integration via Microsoft Graph.
Avoid When
SECURITY RISK: Entra ID API controls authentication and access for entire Microsoft ecosystem — misconfiguration can affect all M365 and Azure resources simultaneously. Conditional Access policy automation must be tested in report-only mode before enforcement. Global Admin role automation requires human approval workflows.
Use Cases
- • Automating user lifecycle management from HR-driven provisioning agents
- • Monitoring sign-in and identity risk from security operations agents
- • Managing Conditional Access policies from security policy agents
- • Integrating Entra ID with HR systems from identity governance agents
Not For
- • Non-Microsoft cloud identity without Azure/M365 ecosystem integration
- • Consumer identity management without enterprise AAD tenant
- • Simple API authentication without enterprise IAM governance
Interface
Authentication
Microsoft Entra ID uses OAuth 2.0 / OpenID Connect for all API access. Microsoft Identity Platform with MSAL (Microsoft Authentication Library). Microsoft Graph API as unified endpoint. Developer documentation at learn.microsoft.com. Change notifications (webhooks) for directory events. SDKs for Python, JavaScript, Java, .NET, Go, PHP. Azure AD B2C and B2B separate APIs. MSAL SDKs for token management.
Pricing
Redmond, Washington. Microsoft Corporation. Entra ID rebranded from Azure Active Directory (2023). 1.3B+ users. De facto enterprise identity standard for M365 organizations. Microsoft Graph as unified API layer. MSAL for authentication. Strong GitHub, Power Platform, and Teams integration. Competes with Okta and Ping Identity for enterprise IAM.
Agent Metadata
Known Gotchas
- ⚠ SECURITY RISK: Entra ID automation affects entire Microsoft ecosystem — Global Admin operations must have human-in-the-loop; use least-privilege service principals
- ⚠ Conditional Access automation — test CA policy changes in report-only mode before enforcement; policy errors can block all users
- ⚠ Throttling with Retry-After — Microsoft Graph throttles aggressively; always implement Retry-After header backoff
- ⚠ Service principal vs delegated permissions — choose correct permission type; service principal for automation, delegated for user context
- ⚠ MSAL token caching — always use MSAL library for token management; handle token refresh and cache properly
- ⚠ PIM JIT roles — Privileged Identity Management activation for elevated roles requires careful audit and time-bound access
