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

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

The /v1.0/security/alerts/* endpoints were retired on October 15, 2026. Microsoft Graph deprecated this legacy alerts API, and requests made to these endpoints fail since that date.

## 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: `/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
- Page: https://www.okapi.bot/providers/microsoft-graph/breaking-changes/v1-0-security-alerts-stops-working/

## Microsoft Graph's words

> The legacy alerts API is deprecated and will be retired on October 15, 2026.
