Send/Receive request/response to RASA using python

Hello everyone,

I’m actually trying to build a chatbot for IT Help purposes . Currently using a simple web app with Flask. and those RASA versions (NLU 0.13.8 - CORE 0.12.4), So I have trained my bot with my own data (data.json), and now I’m stuck in finale step which is to provide an HTTP API to Flask by sending the question and get a response by RASA ,Honestly I don’t know how to do that (And i dont found much things on documentations) , so I need some clear instructions to do that

Thank you

Please tell the command by which you are running rasa core.
