Effective December 31, CME Reference Data API version 1 will be decommissioned. CME Group recommends customers should migrate to CME Reference Data API version 2 as soon as possible. CME Reference Data API version 2 will require customer authorization using a CME Group Login and a registered OAuth 2.0 API ID to access the service. Customers that require access to BrokerTec content must also complete API ID entitlement registration.
