Confirmation needed on BI Publisher REST API for Catalog Management & SOAP API Support Lifecycle

We are implementing a CI/CD pipeline to manage our BI Publisher assets. A core requirement for this automation is a script that can upload BI Publisher catalog objects, particularly data model files (.xdm), from our version-controlled repository to BI publisher.

Our development and research led us to the BI Publisher SOAP Web Services. We have found that the ’CatalogService’ with its ’downloadObject’ and ’uploadObject’ methods, works perfectly for this task.

However, wer are evaluating whether this task can be accomplished using the more modern REST API. Our review of the REST API documentation indicates that its functionality is focused exclusively on „Manage Report”. We can see how to create a report and link it to an existing data model by providing its path, but we cannot find any endpoint or method that allows for the direct upload or download of the .xdm file itself.
