SAP C4 SDK: How to consume an ODATA service in C4 PDI ?

I would like to consume an ODATA service call from CPI in C4 using SDK/PDI. I searched a lot of blogs here in SDN but couldn't find a way to do this development. Also i found a reference which says that it's not possible to consume the ODATA from external systems in SDK, but that reference was in 2016. I am not sure if the situation remains the same ?
