Adding an IDM document from ION via API

Legacy Contributor

I'm wanting to call IDM from an ION dataflow to add a base64 encoded document.  From looking at the API's available it appears that /Items does what I'm looking for.  What I can't work out from the documentation is how to specify the Document Type for the document that I'm creating.  The inputs are:

Setting the attributes and content seems obvious enough but not the Document Type or is that what entityName is?

I ran into the same question on one of my API calls. Entity name is the document type in the API call.
