Updated March 29, 2022: We previously announced the SIEM REST API would be deprecated on 4/1/2022. We’ve listened to customer feedback and are choosing to keep this API active for the time being. We look forward to sharing exciting details about the Microsoft 365 Defender APIs in MS Graph in Q3 2022. Thank you.
In April, we will be retiring the SIEM REST API in the Microsoft Defender for Endpoint. Rather than using this API, we recommend calling the Microsoft 365 Defender Incident API, which is where we will continue to invest our development resources, or the Microsoft Defender for Endpoint Alert API in order to ingest alerts.
If your organization doesn’t use the SIEM REST API, you may safely disregard this message.
Key points
- Timing: The API retirement has been postponed for now, more details expected in Q3, 2022.
- Action: Customers are encouraged to migrate their existing integrations that call the SIEM REST API to one of the above alternatives starting now.
How this will affect your organization
Effective immediately, no new onboarding to the Microsoft Defender for Endpoint SIEM REST API will be possible.
Users and admins will no longer be able to edit the Endpoint/APIs/SIEM web page in the security portal, but they will be able to view existing integration details.
