Can you try the below?

    {
    "addressInformation": {
        "shipping_address": {
            "firstname": "Your name",
            "lastname": "your last name",
            "city": "India",
            "country_id": "IN",
            "region": "Region",
            "postcode": "123456",
            "telephone": "1234567",
            "region_id": 0,
            "street": ["Line1", "Line2"],
            "customer_id": 1,
            "customer_address_id": 1
        },
        "billing_address": {
            "firstname": "Your name",
            "lastname": "your last name",
            "city": "India",
            "country_id": "IN",
            "region": "Region",
            "postcode": "123456",
            "telephone": "1234567",
            "region_id": 0,
            "street": ["Line1", "Line2"],
            "customer_id": 1,
            "customer_address_id": 1
        },
        "shipping_method_code": "freeshipping",
        "shipping_carrier_code": "freeshipping"
    }
}

Make sure the

"shippingMethodCode": "freeshipping",
"shippingCarrierCode": "freeshipping",

are the code(s) available when you retrieve using the shipping methods API: http://magento2_path/index.php/rest/V1/carts/mine/shipping-methods

Hope this helps.
