Migrate from EA Reserved Instance Recommendations API

  • Article
  • 06/06/2024

EA customers who were previously using the Enterprise Reporting consumption.azure.com API to obtain reserved instance recommendations need to migrate to a parity Azure Resource Manager API. The following instructions help you migrate and describe any contract differences between the old API and the new API.

Note

All Azure Enterprise Reporting APIs are retired. You should Migrate to Microsoft Cost Management APIs as soon as possible.

Assign permissions to a service principle to call the API

Before calling the API, you need to configure a Service Principal with the correct permission. You use the service principal to call the API. For more information, see Assign permissions to Cost Management APIs.

Call the reserved instance recommendations API

Use the following request URIs to call the new Reservation Recommendations API.

Supported requests

Call the API with the following scopes:

  • Enrollment: providers/Microsoft.Billing/billingAccounts/{billingAccountId}
  • Subscription: subscriptions/{subscriptionId}
  • Resource Groups: subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}

Get Recommendations

Both the shared and the single scope recommendations are available through this API. You can also filter on the scope as an optional API parameter.

Response body changes

In the new API, recommendations for Shared and Single scopes are combined into one API.
