# How to verify your signature

### Steps

1. Arrange multiple signature data items in alphabetical order. Each data item forms a string in the format "key=value."
2. Connect each data item string with the "&" symbol.
3. Append the secret\_key to the end of the concatenated string.
4. Obtain the signature data by applying MD5 by above string

**Example Data for Signature**

{% code overflow="wrap" %}

```json
{
        "game_id": 1,
        "match_token": "47AD1ED23DB1407720049D586C727C3B",
        "user_ticket": "1843BBAEBC83DDB0E45E378BA37014A9",
        "taste": 0,
        "action": "report_score",
        "score": 5,
        "auth_date": 1704816000
}
```

{% endcode %}

**secret\_key Example** 

```
aE18Vlne8LxlHFCm
```

**Signature Example**

{% code overflow="wrap" %}

```scss
md5("action=report_score&auth_date=1704816000&game_id=1&match_token=47AD1ED23DB1407720049D586C727C3B&score=5&taste=0&user_ticket=1843BBAEBC83DDB0E45E378BA37014A9&secret_key=aE18Vlne8LxlHFCm")
