BMRS APIs and Data Push Service

The BMRS APIs and Data Push Service are designed to allow users to access BMRS data automatically. Depending on requirements, users can decide whether to use the API or Data Push services or a combination of the two.

The APIs use a pull mechanism, so are better suited for users needing ad-hoc access to historical information, or those who are interested in specific flows.

The Data Push Service is a new capability that allows the near real-time publishing of information from the BMRS system. This is useful for those who need the latest information from BMRS pushed to their system in near real time. Further details can be found in the BMRS API and Data Push User Guide (see "Related Content").
