Preview Plugin

This guide details how to integrate the Preview Plugin so that you can simulate joining audiences to preview experiences.
There is so much to take into account before products can go live. Most times you want to be sure that the experience you serve to your customers is authentic and performs on delivery as expected.
To be sure that audiences receive the right content, the preview widget is developed to give you the power to preview content behaviour based on audience traits in your development environment before it is pushed live or to production. The Preview Widget allows you to quickly view personalized content from within your web page for multiple audiences. This means you can preview personalized content for your frontend elements based on various traits before it goes live.
