Args:
AADToken (object): AAD Token used for authentication
CustomAuthHeader (object): A Custom Value for Authorization Header
concurrency (int): max number of concurrent calls
concurrentTimeout (float): max number seconds to wait on futures if concurrency >= 1
customInterval (object): Custom Interval is used to set non-standard time interval, for example, if the series is 5 minutes, request can be set as granularity=minutely, customInterval=5.
errorCol (str): column to hold http errors
granularity (object): Can only be one of yearly, monthly, weekly, daily, hourly or minutely. Granularity is used for verify whether input series is valid.
handler (object): Which strategy to use when handling requests
imputeFixedValue (object): Optional argument, fixed value to use when imputeMode is set to "fixed"
imputeMode (object): Optional argument, impute mode of a time series. Possible values: auto, previous, linear, fixed, zero, notFill
maxAnomalyRatio (object): Optional argument, advanced model parameter, max anomaly ratio in a time series.
outputCol (str): The name of the output column
period (object): Optional argument, periodic value of a time series. If the value is null or does not present, the API will determine the period automatically.
sensitivity (object): Optional argument, advanced model parameter, between 0-99, the lower the value is, the larger the margin value will be which means less anomalies will be accepted
series (object): Time series data points. Points should be sorted by timestamp in ascending order to match the anomaly detection result. If the data is not sorted correctly or there is duplicated timestamp, the API will not work. In such case, an error message will be returned.
subscriptionKey (object): the API key to use
timeout (float): number of seconds to wait before closing the connection
