So i have managed to do a couple of things with item attributes using the API, but I am still dealing with the uphill battle of using the REST/OData APIs in general.
I have been able to get the list of attributes, and I have managed to create an endpoint using an AL query that shows the items with the attributes.
My problem now is to figure out how I can create a new attribute of a given type and associate it with a particular item via a REST/OData POST.
Does anyone have any ideas or pointers?
