Conversations
In this section we will talk about how to send/receive messages from a Chatbot, the first step is the creation of the conversation, once you have the conversation Id you will be able to send a message to the Chatbot through a POST and to receive the message through A GET, while having the capacity to send context information through the body of the POST request as well.
Important: EDDI has a great feature for conversations with chatbots, it's the possibility to go back in time by using the two API endpoints : /undo and /redo !

The conversationId will be provided through the location HTTP Header of the response,  you will use that later to submit messages to the Chabot to maintain a conversation.

Undo and redo :
The undo and redo methods basically allow you to return a step back in a conversation, this is done by sending a POST along with bot and conversation ids to /bots/{environment}/{botId}/redo/{conversationId} endpoint, the GET call of the same endpoint with the same parameters will allow you to see if the last submitted undo/redo was successful by receiving a true or false in the response body.
