  title: Alerts API
  description: '**Note:** API operations for the creation or retrieval of API, Page Load, or Web-Transaction alert rules are not available for ThousandEyes for Government instance.


    You can manage the following alert functionalities on the ThousandEyes platform using the Alerts API:


    * **Alerts**: Retrieve alert details. Alerts are assigned to tests through alert rules.


    * **Alert Rules**: Conditions that you configure in order to highlight or be notified of events of interest in your ThousandEyes tests. When an alert rule’s conditions are met, the associated alert is triggered and the alert becomes active. It remains active until the alert is cleared. Alert rules are reusable across multiple tests..


    * **Alert Suppression Windows**: Suppress alerts for tests during periods such as planned maintenance. Windows can be one-time events or recurring events to handle periodic occurrences such as monthly downtime for maintenance.


    For more information about the alerts, see [Alerts](https://docs.thousandeyes.com/product-documentation/alerts).

      description: 'Returns a list of alerts. Only active (triggered) alerts are returned by default.

        When no time filter is specified, only triggered alerts from the last 90 days are returned. To retrieve triggered alerts from a specific date range, specify `state=trigger` with `startDate` and `endDate`. Only use `window` for a lookback interval ending at the current request time.

        To retrieve cleared alerts, specify `clear` in the optional `state` parameter. Note that the `state` parameter only accepts a single value, so to get both active and cleared alerts within a time range, two separate requests are needed.

        Time filters (`window`, `startDate`, `endDate`) are applied differently depending on state: - For `state=trigger`: filters by when the alert started. - For `state=clear`: filters by when the alert cleared. - When state is not specified: returns cleared alerts within the time range plus any currently active alerts that started before the end of the range.'
