[Plugin] Http/s REST, blueprintable JSON and Parse REST API manager at once (VaRest)

I have made a ChatBot for the MetaHuman.

How and where I can implement Rest API, so that I can send a message and get a reply to it, on to the ChatBot.

I have also tried using this Plugin. But I couldn’t find the exact solution.

It will be an immense help if it is resolved. Thank You.

(I have been using Google Assistant as a source, it is working fine. But now i wanted to add Rest API)
