Migrate from EA Reserved Instance Charges API

EA customers who were previously using the Enterprise Reporting consumption.azure.com API to obtain reserved instance charges need to migrate to a parity Azure Resource Manager API. Instructions to do this are outlined below along with any contract differences between the old API and the new API.

Assign permissions to an SPN 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 ACM APIs.

Call the Reserved Instance Charges API

Use the following request URIs to call the new Reserved Instance Charges API.
