After you’ve added the RSS app, add your first feed:
Next to Feed URL, paste the web address of the feed you’d like to subscribe to.
Select a channel where feed updates will appear.
Click Subscribe to this feed to finish.
You’ll see updates post in Slack the next time the site is updated. 🎉
Note: The RSS app will store a bookmark with a date of the last item retrieved from a feed. The next time the app polls for new items, it will only retrieve items with a datestamp later than the date saved in the bookmark.
Step 3: Add more feeds
If you'd like to subscribe to more RSS or Atom feeds, use the steps below.
Copy the feed address from the website you want to add.
In your Slack workspace, go to the channel where you’d like feed updates to appear.
Click the slash icon next to the message field.
Type /feed into the search field at the top of the menu and click on it to add the command to the message field.
Following /feed in the message field, type subscribe and the feed address.
Send the message.
Tip: You could create a private channel, e.g. #my-rss, where you can add all your favorite feeds to make Slack your RSS reader of choice.
Manage your RSS feeds
There are a number of useful things you can do with the /feed command:
Use /feed list to see all the RSS feeds added to a channel, along with their unique ID number
Use /feed remove [ID number] to unsubscribe from a feed
Use /feed help for a reminder of how to use /feed commands
To manage any feed you’ve added to your Slack workspace, regardless of channel, head to the RSS page in the Slack Marketplace and click Configure.
