Azure Monitor - Send custom log action

The Send custom log action sends custom logs to Azure Monitor.

DEPRECATED - MIGRATION REQUIRED

This action uses the HTTP Data Collector API (opens new window), which will be deprecated on December 8, 2025, and will stop working in September 2026.

We recommend that you migrate to the Inject custom logs action. It uses the newer Logs Ingestion API (opens new window) with client credentials authentication.
