There are two different interfaces for handling provisioning of buckets, subscribers and products. One is implemented as APL functions and the other as a REST web service.
Provisioning always targets a specific, internally predefined, area. Changes in one area is not reflected in the other. There are two different areas (TEST and PROD) the provisioning can target. A typical use case would be to provision data to the TEST area and, when considered ready, copy the content of TEST to PROD where a workflow can access them.
Using two different areas - one for provisioning and one for runtime - makes it possible to test the configurations before moving them into production.
