Call to action: update older Microsoft Sentinel content as code

March 2026

Call to action: update older Microsoft Sentinel content as code (Sentinel repositories) API versions before June 2026
Starting June 1, 2026, older API versions used by Microsoft Sentinel repositories will no longer be supported. This change impacts all Source Control and Source Controls actions in the Microsoft Sentinel REST API for the affected API versions.

The retired API versions will no longer be supported, and requests using them will fail. Existing repository connections created with those APIs aren't affected, and the repositories will continue to operate.

Required action
If you're using APIs to create or manage repository connections, transition to API version 2025-06-01 or 2025-07-01-preview before May 1, 2026 to avoid service disruption.

Affected API versions
The following API versions will be retired on May 1, 2026:

• Preview API versions (click to expand)
• Stable API versions (click to expand)

Recommended API versions to use:

• 2025-09-01 (stable)
• 2025-06-01 (stable)
• 2025-07-01-preview (preview)
