# Create Conversation

Called when a new conversation has been created via the Fin Messenger.
Note we provide the initial message from the conversation as we know many help desks require this to be provided when creating a conversation.
The response requires both the conversation object and the message object so that these can be mapped correctly to their Fin equivalents.
