public class BaseResponse
{
    public string ErrorCode;
    public string Message;
    public string WithdrawalKey;
    public string BlockKey;
}

Save Data Class

public class StorageSave
{
    static string path = "https://service-storage-api.playnanoo.com/storage/v20221001/save";

    [Serializable]
    public class Req : DeviceInfo
    {
        public string storage_key;    // Key of the data to save
        public string storage_value;  // Value of the data to save
        public string isPrivate;      // Blocks external players from accessing the data when access restriction is set

        public IEnumerator Send(string storage_key, string storage_value, bool isPrivate, Action<Res> onSuccess, Action<BaseResponse> onError)
        {
            if (!string.IsNullOrEmpty(storage_key)) this.storage_key = storage_key;
            if (!string.IsNullOrEmpty(storage_value)) this.storage_value = storage_value;
            this.isPrivate = isPrivate ? "on" : "off";

            yield return HttpClient.Send<Req, Res>(
                UnityWebRequest.kHttpVerbPUT,
                path,
                requireToken: true,
                body: this,
                onSuccess: onSuccess,
                onError: onError
            );
        }
    }

    [Serializable]
    public class Res : BaseResponse
    {
        public string Status;
    }
}

Usage Example

public void SaveGameData()
{
    StorageSave.Req req = new StorageSave.Req();

    // Serialize game data to JSON
    var gameData = new
    {
        level = 10,
        score = 1000,
        items = new[] { "sword", "shield", "potion" }
    };
    string jsonData = JsonUtility.ToJson(gameData);

    StartCoroutine(req.Send(
        storage_key: "player_game_data",
        storage_value: jsonData,
        isPrivate: false,  // Save as public data
        onSuccess: res =>
        {
            Debug.Log("Data save successful");
        },
        onError: error =>
        {
            Debug.LogError($"Data save failed: [{error.ErrorCode}] {error.Message}");
        }
    ));
}

Data Format

Since storage_value is a string, it is recommended to serialize complex data structures as JSON for storage.

Auto-save

It is recommended to save game data at important points (level up, item acquisition, etc.). Check network status and implement retry logic in case of save failure.
