# Azure Monitor: Data Collector API retirement

Retirement date for the Data Collector API used to ingest custom logs into Azure Monitor logs: 14 Sep 2026. Microsoft names the Data Collection Rules based Log Ingestion API as the replacement.

- Effective date: 14 Sep 2026
- Cloud: [Azure](https://eolwatch.dev/cloud/azure.md)
- Service: [Azure Monitor](https://eolwatch.dev/services/azure/monitor.md)

## What breaks

Clients that send custom logs to Azure Monitor logs through the Data Collector API are affected. Data Collector API endpoints become unavailable after the retirement date. The source warns of ingestion errors and data loss for clients that have not transitioned.

## What to do

Transition to the DCR-based Log Ingestion API before the retirement date, using the Microsoft guide: [transition to the DCR-based Log Ingestion API](https://aka.ms/datacollectorapimigrate).

## Replacement

DCR-based Log Ingestion API
