I am trying to connect to a XML-RPC API-->
I cannot find any guide on how to connect to such an API system...
Can anyone point me in the right direction
Hey @Adewole_Ekanola! This isn't something I have extensive experience with, but I can provide you with some pointers and resources. 
The first and seemingly most obvious option is to use the built-in gRPC resource connector, but it's primarily built to support the protobuf data type and I'm not sure if it can be configured to use XML. It may be possible with reflection, but that would have to be enabled server-side.
The other option is to import a JS (or Python if you're using a workflow) library that would allow you to instantiate an XML-RPC client and talk to your API that way. You can read more about importing custom libraries here. There are a variety of libraries on npm that you can peruse, most of which have decent documentation.
I'll continue to explore different options here but hopefully that's enough to get you started!
