Flowise API integration into Unreal Engine

I am currently developing a chatbot for unreal engine, i know how to do the speech to text and character animations, but the only problem i have is trying to make an api call to Flowise which is an open sourced LLM. I have used Http request and VARest as plugins but struggle to get a response to an open URL website that was created with flowise. So i just need a little bit of blueprint coding / documentation to make the correct API call to so that the player can chat with the FLOWISE api. If you are able to do this, then i would like you to be able to make separate api call to different chatbots with different API calls to Flowise in the unreal engine. I am using unreal engine 5. Please let me know if you are interest and what your price would be. I will send further details to interested candidates.
thank you
