-This article helps developers that have built custom solutions using the [Azure Enterprise Reporting APIs](../manage/enterprise-api.md) to migrate to Microsoft Cost Management APIs. Service principal support is available in the newer Cost Management APIs and they are still actively being developed. Consider migrating to them instead of using the older Azure Enterprise Reporting APIs. The older APIs are being deprecated. This article helps you understand the differences between the Azure Enterprise Reporting APIs and the Cost Management APIs, what to expect when you migrate to the Cost Management APIs, and the new capabilities that are available with the Cost Management APIs.
+This article informs developers that have built custom solutions using the [Azure Enterprise Reporting APIs](../manage/enterprise-api.md) about important changes.
