Data Integration Service (DIS) - Documentation for external integrating systems
Description
Data Integration Service (called D-I-S on a daily basis) is a case flow coordination service. It handles information about the flow of cases between Origin Systems and Consumer Systems.
Origin Systems
A Origin System is the "owner" of a case. It is where the case is created, but it also holds the responsibility to update, close, or delete (if required). Every change made to the case after creation besides closing and deletion is an update.
Each Origin System has the responsibility to create a data model for the CaseDetails and therefore different Origin Systems can have different data models for CaseDetails. It is the responsibility of the Origin System to expose the endpoint for fetching CaseDetails by Consumer Systems. The endpoint should be secured by an access token from KeyCloak.
Consumer Systems
Consumer systems are the subscribers of cases and corresponding data delivered through DIS by the Origin Systems. To authorize a consuming system and make calls to DIS an access bearer token is needed. This token is generated using KeyCloak, with the use of clientId and clientSecret. To add a system to KeyCloak a realm manager (the Cross team) has to set up the client. Once the client has been created the clientId and clientSecret should be provided to the external integrating system. The integrating system should implement the call KeyCloak to obtain the bearer token and place this in the header when sending requests to DIS and the Origin System (for CaseDetails).
The structure of data delivered is dictated by each Origin System depending on the need an available data. Only EGDW.CaseMetadata is static and set by DIS, the content of CaseDetails and how it is mapped is a contract between the Origin System and the Consumer System. This means the Id, Created, and Updated are set by the Origin System.
