# GET /v1.0/security/alerts stops working

Calls to GET /v1.0/security/alerts on Microsoft Graph stopped working on October 15, 2026.

On October 15, 2026, Microsoft Graph retired the legacy alerts API. Calls to GET /v1.0/security/alerts fail since that date. The endpoint is no longer supported and requests to it do not return data.

## What to use instead

Migrate to the alerts and incidents API (/security/alerts_v2).

- API: Microsoft Graph (graph.microsoft.com)
- Kind: Endpoint removal
- Announced: April 15, 2024
- Takes effect: October 15, 2026
- Calls after that day: fail
- Calls it hits: `GET /v1.0/security/alerts`
- Source: [Announcement](https://learn.microsoft.com/en-us/graph/api/alert-list?view=graph-rest-1.0)
- Verified: November 6, 2026, against Microsoft Graph's own pages
