iron-ajax

The iron-ajax element exposes network request functionality.

<iron-ajax auto
    url="https://www.googleapis.com/youtube/v3/search"
    params='{"part":"snippet", "q":"polymer", "key": "AIzaSyAuecFZ9xJXbGDkQYWBmYrtzOGJD-iDIgI", "type": "video"}'
    handle-as="json"
    last-response="{{ajaxResponse}}"></iron-ajax>

With auto set to true, the element performs a request whenever its url, params or body properties are changed. Automatically generated requests will be debounced in the case that multiple attributes are changed sequentially.

Note: The params attribute must be double quoted JSON.

You can trigger a request explicitly by calling generateRequest on the element.
