Consumers Energy Green Button Connect My Data API

The Consumers Energy Green Button Connect My Data API exposes customer-authorized electric and natural-gas usage data to registered third parties using the NAESB ESPI / Green Button standard. Authorization uses OAuth 2.0 with single sign-on or test-account scopes; data is delivered as Green Button XML or JSON via UtilityAPI's standardized endpoints (Meters, Bills, Intervals, Billing Summaries). Third parties register with Consumers Energy, are issued a client_id, and start in sandbox mode before being approved for live data.
