I have a webpage where I want to use dialogflow chatbot. This is a custom chat window, so I don't want to use one click integration. I am able to access the chat agent V1 API using javascript/ajax (by passing client access token in the request header).
But I don't know how to do it in V2 API. The dialogflow documentation is not clear to me(I have setup Authentication by referring this link. I don't know how to proceed further). I'm not familiar with Google cloud either. So a working sample or a step by step how to access the API guideline will be very much appreciated.
