    description <<-MD

      The Aftership agent allows you to track your shipment data from aftership.

      To be able to use the Aftership API, you need to generate an `API Key`.
      You can generate an api key by visiting `apps > app and click add` on aftership website. 

      The agent is limited to 600 reqs/min per account. You do need a paying plan to use their tracking feature.

      Required Options:

      * `Content-Type` application/json
      * `aftership_api_key` - YOUR_API_KEY.
