How To Transition from Retired Azure EA Billing APIs

Transitioning to Enhanced Cloud Cost Management with Azure's New APIs.

With the retirement of Azure Enterprise Reporting APIs as of this month, Microsoft has forced users to the Cost Management APIs, marking a significant advancement in how Azure users can manage and analyze their cloud expenditures. These newer APIs not only streamline processes but also bring forth enhanced capabilities and improved security features, making them an essential upgrade for businesses relying on Azure EA billing and cost reporting.

Understanding the Changes

The new Cost Details API replaces all previous Usage Details APIs, offering asynchronous report generation. This will require a programmatic polling mechanism towards the Cost Management API to know when the CSV data is ready for download from Azure blob storage.

Another change is the API endpoint transition from to, signifying the integration of Cost Management APIs into the broader Azure Resource Manager framework. This transition allows for the usage of additional functionalities such as Budgets, Alerts, and Exports, providing a comprehensive toolkit for managing Azure costs more efficiently.

The shift from Azure Enterprise Reporting to Cost Management APIs isn't just a technical update—it's a strategic enhancement. The old APIs operated on basic authentication methods using generic API authentication, which is now replaced by the more secure Microsoft Entra authentication that utilises user tokens or service principals. This shift not only enhances security but also simplifies the management of permissions and scopes.

Practical Tips for a Smooth Transition

To ensure a seamless migration, organizations should begin by mapping their current usage of Azure Enterprise Reporting APIs to the corresponding Cost Management APIs. Testing these new API integrations in a controlled environment before full deployment is advisable to address any issues that may arise during the transition.

Leveraging Exivity for Azure Cost Reporting

For Exivity users, integrating these changes into your existing setups can be streamlined using our recently updated Azure EA Extraction and Transformation templates. These templates allow you to effectively report on Azure EA consumption data, aligning with the new API structures. Learn more about setting this up with our detailed tutorial.
