Answer №1

One way to encode credentials is by using the btoa function:

<iron-ajax
auto
url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}'
handle-as='json'
method='get'
headers='{"Authorization": "Basic [[basicAuth(username, apiKey)]]"}'
debounce-duration='300'
last-response='{{json}}'></iron-ajax>
<script>
    Polymer({
        ...
        basicAuth(username, password) {
            return window.btoa(username + ':' + password)
        },
        ...
    });
</script>
