# Get Temperature (Skin) Data
TIP
This guide assumes that your app has already been authorized and the snippet of code that I will show you can access to a valid FitbitCredentials instance, here called fitbitCredentials, the Fitbit OAuth 2.0 client ID, here called clientID, and the Fitbit client secret, here called clientSecret.
Temperature (Skin) data (opens new window) contain details about a user's Temperature (Skin) data. In Fitbitter, a datapoint is expressed by the FitbitTemperatureSkinData model.
In particular, an instance of FitbitTemperatureSkinData has the following fields:
  /// The user encoded id.
  String? userID;
  /// The date of monitoring of the data.
  DateTime? dateOfMonitoring;
  /// The value of the data.
  double? value;
  // The type of skin temeperature log created.
  String? logType;
An example is:
FitbitTemperatureSkinData(userID: 7ML2XV, dateOfMonitoring: 2022-05-08 00:00:00.000, value: 0.3, logType: 'dedicated_temp_sensor',)
Information about the user's Temperature (Skin) data can be obtained in three steps:
# Step 1: Instanciate a manager
First, you need to instanciate a FitbitTemperatureSkinDataManager
    FitbitTemperatureSkinDataManager fitbitTemperatureSkinDataManager = FitbitTemperatureSkinDataManager(
        clientID: '<OAuth 2.0 Client ID>',
        clientSecret: '<Client Secret>',
    );
# Step 2: Create the request url
Then, you have to create a url object, FitbitTemperatureSkinAPIURL to fetch the Temperature (Skin) data as:
    FitbitTemperatureSkinAPIURL fitbitTemperatureSkinAPIURL = FitbitTemperatureSkinAPIURL.day(
                                    date: DateTime.now(),
                                    fitbitCredentials: fitbitCredentials,
                                  );
where date is the day you want to fetch FitbitTemperatureSkinData from and fitbitCredentials is the FitbitCredentials instance obtained during the authentication step.
TIP
For the complete list of possible FitbitTemperatureSkinAPIURL, defined for different time ranges, please refer to the API Doc (opens new window).
# Step 3: Get the data
Finally you can obtain the Temperature (Skin) data using
    List<FitbitTemperatureSkinData> fitbitTemperatureSkinData = await fitbitTemperatureSkinDataManager.fetch(fitbitTemperatureSkinAPIURL);
