How to pass a history key to a call to /chat?

[Und3rf10w]

Using the most simple example with a conversational chain, how does one populate the history (or chat_history) input ?

For example, when calling /chat, the request might look something like:

curl -N -X POST -H "Accept: text/event-stream" -H "Content-Type: application/json" -d '{"input": "Hello", "chat_history": ""}'

How do you properly specify values for chat_history?

Okay, I think you can just use:

messages = langchain.schema.messages.from_dict(json.loads(request.chat_history))
for message in messages:
    langchain_object.memory.chat_memory.add_message(message)
