Account aggregation is one of the most popular use-cases in banking when more than one systems available. It requires an orchestration logic that integrates with multiple internal and external APIs and provides data via a single point of query. This RAML specification should serve as an API design best practice to abstract that complexity with a light-weight RESTful interface that could be reused by developers in other integrations projects e.g. building a mobile app that requires account data.
This API implementation is one of many components included in Catalyst Accelerator for Banking. It provides organizations with connectivity assets that accelerate project delivery in financial services, including pre-built API designs and implementations that support core banking business processes.
