Hi,
The documentation on the developer portal says that aliases cannot be used with the REST API and only the internal IDs must be used.
https://developer.m-files.com/APIs/REST-API/Concepts/#obtaining-metadata-structure-element-ids
While this is technically true, it is, however, possible to resolve those IDs from aliases using the endpoint REST/structure/metadatastructure/itemidbyalias.
https://developer.m-files.com/APIs/REST-API/Reference/resources/structure/itemidbyalias/
This way the code does not rely solely on hard-coded IDs. I think it would be good to mention this in the documentation.
