All transactional requests to the Federal data services hub shall be performed via web services. These services shall be invoked by State IT systems via application programming interfaces (API) or Web APIs that are accessed via secure Hypertext Transfer Protocol (HTTP) and shall be executed on the system hosting the requested services. The CMS web services shall accept request from trusted sources, perform the function based on the request, and return a response to the State system. CMS shall publish these web services in the CMS Service Catalog, which shall contain all services available to the states and the definitions of the standards that must be met to request the service and standard data format for the data provided when making the request and the data that shall be returned.
CMS is still determining the best mechanism for how batch and bulk data transactions will be designed and implemented. At this stage, CMS believes that there shall be a need to establish both web services and possibly alternate interfaces to meet batch and bulk data transaction requirements.
