On 14 September 2026, we’ll retire Data Collector API for ingesting custom logs to Azure Monitor logs. Before that date, you’ll need to transition to the Data Collection Rules based log ingestion API that provides all the functionality of the Data Collector API, as well as new ones, including:
Secure token-based authentication
Full control over the shape of the destination table
Ability to filter and transform data during ingestion
To avoid ingestion errors and data loss, transition to the DCR-based Log Ingestion API before 14 September 2026. Data Collector API endpoints will become unavailable after the cut over date.
