# 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());
        }
    });
