Hello.
Not sure about the web interface – I’ve never used it because we made our own – but the Remote Control server (which the web interface connects to) supports calling UFUNCTIONs (including Blueprint functions) by name if you have an object path. Note that the object path changes depending on the mode that you’re in (ex: Play In Editor mode).
In our case, we call it like:
PUT http://our.remote.control.address/remote/object/call
{ "objectPath":"/Game/Path/Maps/UEDPIE_0_MyMap.MyMap:PersistentLevel.MyProxyObject_C_1",
"functionName":"MyFunctionName",
"parameters": {
"SomeStructureListVariable": [
{"VariableOne": "blah1", "VariableTwo": "blahOne"},
{"VariableOne": "blah2", "VariableTwo": "blahTwo"}
]
}
}
