How to Include Chat History When Using Google Gemini's API

Question

I'm trying to feed chat history to the Google Gemini API using a cURL request. I want to provide both the user's previous input and the model's previous response in the request. Here's the cURL command I'm using:

curl --location 'https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-flash:generateContent?key=' \
--header 'Content-Type: application/json' \
--data '{
    "contents": [
        {
            "role": "model",
            "parts": [
                {
                    "text": "...model data"
                }
            ]
        },
        {
            "role": "user",
            "parts": [
                {
                    "text": "...user input"
                }
            ]
        }
    ],
    "history": [
        {
            "role": "user",
            "parts": [
                {
                    "text": "Hello, I have 2 dogs in my house."
                }
            ]
        },
        {
            "role": "model",
            "parts": [
                {
                    "text": "Great to meet you. What would you like to know?"
                }
            ]
        }
    ]
}'

I'm not sure if I'm formatting the contents and history sections correctly.

I expected the model to understand the previous exchanges and continue the conversation accordingly.

History is part of the same cotent you just have to put it in order

"contents": [
        {
            "role": "model",
            "parts": [
                {
                    "text": "...model data"
                }
            ]
        },
        {
            "role": "user",
            "parts": [
                {
                    "text": "...user input"
                }
            ]
        }
    ],

The final one is the current one that the model will answer based upon the history or all the other entries in contents.
