    default_schedule "every_10m"

    description <<~MD
      The Aftership agent allows you to track your shipment from aftership and emit them into events.

      To be able to use the Aftership API, you need to generate an `API Key`. You need a paying plan to use their tracking feature.

      You can use this agent to retrieve tracking data.

      Provide the `path` for the API endpoint that you'd like to hit. For example, for all active packages, enter `trackings`
      (see https://www.aftership.com/docs/api/4/trackings), for a specific package, use `trackings/SLUG/TRACKING_NUMBER`
      and replace `SLUG` with a courier code and `TRACKING_NUMBER` with the tracking number. You can request last checkpoint of a package
      by providing `last_checkpoint/SLUG/TRACKING_NUMBER` instead.

      You can get a list of courier information here `https://www.aftership.com/courier`

      Required Options:

      * `api_key` - YOUR_API_KEY.
      * `path request and its full path`
