HTTP Requests From a Custom Script in One Identity Manager 8.x

Is it possible to do http(s) requests from a custom script in Designer? I have a target that has a very odd API. As such I have created a custom target using scripts for synchronization. In insert script, for example, I need to call the API using a HTTP Post call and pass some XML. However I cannot find any documentation or valid way to do that in VBScript that the compiler seems to allow. Any suggestions on working methods?
