This API is for getting all existing labels for one or all ECM document types for a given locale.
The locale used is the one received in the HTTP request (The preferred Locale that the client will accept content in, based on the Accept-Language header. If the client request doesn't provide an Accept-Language header, this method returns the default locale for the server).
Note: The document type IDs are found on search results entries representing ECM files.
The order of the parameters in the requests do not matter. The parameter names are case-sensitive; they must be entered in the format documented. Any unknown or unsupported parameters submitted as part of a request will be ignored.
The response is in json format. It contains a json object mapping ID->label
