This plugin takes a list of Bubble Things and converts it to RSS XML. Including the appropriate XML declarations to make it an RSS feed.
For any fields called "title", "link", "description" in your Bubble thing - these will be mapped to an RSS "item" - with fields the same name. Optionally specify particular named fields to map to "title", "link", "description".

If your requirement is for another specific XML format - it's likely I can easily adapt this to your specific XML document requirements.  

Contact me if you need this plugin customised for your particular XML structure. [email protected]

The returned XML will look something like this:

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">

With RSS feeds generally you want them to be publically available endpoints. Bubble Backend Workflows are ideal for this.
