    url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}'
    handle-as='json'
    method='get'
    headers='{"Authorization": "Basic base64credentials"}'
    debounce-duration='300'
    last-response='{{json}}'></iron-ajax>


<iron-ajax
    auto
    url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}'
    handle-as='json'
    method='get'
    headers='{"user": "username:apikey"}'
    debounce-duration='300'
    last-response='{{json}}'></iron-ajax>
