# Manage Users, Security Alerts And Team Plans In Microsoft 365 With Microsoft Graph **Published:** 2026-11-11 **Author:** Kin Lane **Canonical:** https://apievangelist.com/2026/11/11/manage-users-security-alerts-and-team-plans-in-microsoft-365-with-microsoft-graph/ If your business runs on Microsoft 365, a lot of your day goes into the same handful of chores. Adding a new hire and setting up how they sign in. Checking whether a security alert needs attention. Keeping the team's plans and tasks up to date. Making sure every laptop has the right apps. You can click through admin screens for all of it, or you can let software do it for you. Microsoft Graph is how that happens: it is an API, a way for one piece of software (or an AI assistant) to ask another to do something, and it reaches into most of what your Microsoft 365 tenant holds. Here is the [Microsoft Graph profile on APIs.io](https://apis.io/providers/microsoft-graph/). ## What Microsoft Graph does Microsoft describes Microsoft Graph as the gateway to data and intelligence in Microsoft 365, a single programming model for reaching data in Microsoft 365, Windows 10 and Enterprise Mobility + Security. In plain terms, it is one front door for your users, groups, mail, files, devices, security signals and plans, instead of a separate door for each product. It is a hosted service, so you call Microsoft's endpoint rather than running anything yourself. You can find more at [microsoft.com](https://www.microsoft.com). On APIs.io we index 71 Microsoft Graph APIs and map them to 20 business capabilities. That is a lot of surface, so I am going to stay with the jobs most small and mid-sized businesses actually have. ## What you can get done ### [Identity & Access Management](https://apis.io/capabilities/identity-access-management/) This is who can get in, and how. When someone joins, changes roles or leaves, you need their sign-in methods and access to follow. Microsoft Graph exposes 2,996 operations in this capability, which tells you how much of Microsoft 365 identity is reachable from software. A few of the basics: - `GET /users/{user-id}/authentication` looks up how a person is set up to sign in. - `PATCH /users/{user-id}/authentication` changes that setup. - `GET /users/{user-id}/authentication/emailMethods` lists the email addresses a person can use to verify who they are. - `POST /users/{user-id}/authentication/emailMethods` adds a new email verification method for a person. Wire these into your onboarding checklist and the account setup stops depending on someone remembering every step. ### [Threat Detection & Response Management](https://apis.io/capabilities/threat-detection-response-management/) Security tools raise alerts, and someone has to look at them, group them and close them out. With 263 operations here, Microsoft Graph lets you pull those alerts and incidents into whatever your team already watches, whether that is a ticketing system, a chat channel or a weekly report. - `GET /security/alerts_v2` lists current security alerts. - `GET /security/alerts_v2/{alert-id}` pulls the detail on a single alert. - `PATCH /security/alerts_v2/{alert-id}` updates an alert, for example to mark it as being handled. - `GET /security/incidents` lists incidents, which are groups of related alerts. ### [Project Management](https://apis.io/capabilities/project-management/) Microsoft Planner is where many teams keep their plans and tasks. With 216 operations in this capability, you can create plans and keep them in sync with the rest of your business, say, opening a plan automatically when a new client signs. - `GET /me/planner/plans` lists the plans you are part of. - `POST /me/planner/plans` creates a new plan. - `GET /me/planner/plans/{plannerPlan-id}` gets the detail of one plan. - `GET /groups/{group-id}/planner` reads the planner for a whole team group. ### [IT Application Management](https://apis.io/capabilities/it-application-management/) Making sure everyone's devices have the right apps is tedious work. These 471 operations cover the apps your organization manages and who they are assigned to. - `GET /deviceAppManagement/mobileApps` lists the apps you manage. - `POST /deviceAppManagement/mobileApps` adds an app to that list. - `PATCH /deviceAppManagement/mobileApps/{mobileApp-id}` updates an app's settings. - `GET /deviceAppManagement/mobileApps/{mobileApp-id}/assignments` shows who an app is assigned to. ### [IT Operations Management](https://apis.io/capabilities/it-operations-management/) The same idea, applied to device settings. With 161 operations here, you can keep configuration consistent across company machines. - `GET /deviceManagement/deviceConfigurations` lists your device configuration profiles. - `POST /deviceManagement/deviceConfigurations` creates a new profile. - `PATCH /deviceManagement/deviceConfigurations/{deviceConfiguration-id}` changes an existing one. ## Getting started Microsoft Graph is a hosted service you call over the web. I could not find a clear access model recorded in our profile, so start with Microsoft's own documentation, beginning with the [admin resources](https://learn.microsoft.com/en-us/graph/api/resources/admin?view=graph-rest-1.0), the [agreement resource](https://learn.microsoft.com/en-us/graph/api/resources/agreement?view=graph-rest-1.0) and [agreement acceptance](https://learn.microsoft.com/en-us/graph/api/resources/agreementacceptance?view=graph-rest-1.0). For cost, see the [Microsoft Graph pricing section on APIs.io](https://apis.io/providers/microsoft-graph/#pricing). On APIs.io you can browse the full [Microsoft Graph profile](https://apis.io/providers/microsoft-graph/), and individual APIs such as [Admin.service Announcement](https://apis.io/apis/microsoft-graph/microsoft-graph-admin-serviceannouncement-api/) for Microsoft 365 service health and message center posts, [Admin.edge](https://apis.io/apis/microsoft-graph/microsoft-graph-admin-edge-api/), and [Agreement Files](https://apis.io/apis/microsoft-graph/microsoft-graph-agreement-files-api/) for the terms people accept before getting access. Pick the one chore that eats the most of your week, whether that is onboarding, alerts or plans, and hand the list of operations above to whoever builds your automations, or to your AI assistant.
