Hey, hoping someone can point me in the right direction. I want to get all the latest items from an RSS feed and post these in a specific Rocket.Chat channel. I only want items I’ve not posted before (could be more than 1 new RSS post at a time).
RSS URL - Free Games Finders RSS Feed
I’ve tried testing this with an RSS feed that posts every 30 seconds (see below for URL) to test it and it keeps on posting the same things over and over again (with multiple RSS feeds in one block of text instead of separate posts or sometimes posts an empty message).
This is what I’ve got so far:
