How to get an RSS/Atom feed of all listings in your marketplace
The RSS/Atom feed in your marketplace contains the 50 most recent listings. All listings (all types, all attributes...) go to that feed: there is no filter. You can use that feed with third-party services to build some automation.
How to access the RSS/Atom feed for listings?
You can find your RSS/Atom feed at https://your.marketplacedomain.com/listings.atom.
The RSS/Atom feed is only available in the public marketplace. If your marketplace is private, this feed won't contain any information.
What does the RSS/Atom feed contain?
The feed contains the most recent listings in your marketplace.
Each entry lists the listing:
URL
publication date and time
last update date and time
title
unique ID
description text
first picture
category
price, currency, and pricing unit
order type
author name
address and geolocation
number of comments
It is automatically updated whenever a new listing is published.
What can you do with this feed?
You can follow that RSS/Atom feed in your preferred RSS/Atom ready (like Feedly).
You can also use it as a source for automation tasks with third-party services like IFTTT.
You can then build some advanced automated tasks like auto-post on Facebook/Twitter, receive an email/notification when a user posts a new listing, etc.
