The Attachment Tags API

The JavaScript API provides methods to retrieve information about the attachment tags defined by the app.

This enables a view developer to access information from the companion file (for example, the description of an attachment tag), rather than having to duplicate that information within the custom view.

The App.getAttachmentTags() method returns a promise (see The Promise API ), which resolves to an array of AttachmentTag objects. These objects have methods to get the name, description, and other details of an attachment tag.
var app = insight.getView().getApp();
app.getAttachmentTags().then(function (tags) {
    console.log('The app defines the following tags:');
    for (var i = 0; i < tags.length; i++) {
        console.log(tags[i].getName());
    }
});
