How can I test Fast Bundle on an unpublished theme?

You can test the Fast Bundle app on an unpublished theme. The easiest way to do that is by contacting us! You can request it via the help widget in the right bottom corner (chatbot) of your Fast Bundle admin panel or send an email directly to We will handle it for you ASAP. But if you need to do it yourself, please follow these steps:

1- Go to the “edit code” page of the theme you want to add Fast Bundle into. To achieve this on the Theme tab click on the Action button for the target theme and then click on the “Edit code” option.

2- Open the theme.liquid file. Find “</body>” in this file. Add the following code just before the “</body>“. Then save the file.
{% render ‘fast_bundle_service’ %}

3- From the sidebar menu that displays theme files, find the "Snippets" directory and click on Add a new snippet just below it. Enter the “fast_bundle_service.liquid” as its name. Then copy and paste the below lines in the created file. Be sure that replace all {shop_domain} with your shop’s domain.
{% unless page.handle == “collection-bundle” %}
<script id=“rbrfastbundleservicescript170428793023” type=“text/javascript” async src=“{shop_name}“></script>
{% else %}
<script type=“text/javascript” async src=“{shop_name}“></script>
<link rel=“stylesheet” href=“”>
{% endunless %}

Very important notice:

Revert the above steps after your test ends (remove the {% render ‘fast_bundle_service’ %} from your theme.liquid file and delete the fast_bundle_service.liquid file.). If you don’t revert the above steps, the Fast Bundle app won’t uninstall from your shop completely and your offers will continue displaying on your shop unless you delete the app.
