All Modules for Twitter are given access to make requests on the Users' behalf. All requests are automatically authenticated.

Here is an example of requesting the current User from Twitter:

const { identity } = this.identity;

const response = await window.casthub.fetch({
    integration: 'twitter',
    method: 'GET',
    url: 'users/show',
    data: {
        user_id: identity,

This supports the Twitter API.
