The ScreenCloud for Slack Feed pulls messages from a Slack channel and turns them into posts on your screens, so updates shared in Slack reach your audience without any extra editing or design work.
About this Feed
Instant Publishing for the Content That Matters
Post a message in your Slack channel, from desktop or mobile, and it's automatically picked up and turned into a post on your screens — no separate step to create or format anything.
No Design Skills Needed
Your screens handle the formatting automatically, adapting to whatever's in the message, whether that's text, an image, a video, or a link, so every post looks polished without any design work.
Simple to Connect and Manage
Once the connection is set up, anyone with access to the channel can get content onto your screens without any extra technical input. Use AI Instructions to fine-tune exactly what comes through.
Setting Up the ScreenCloud for Slack feed
Adding the Feed to a Collection
In your Collection:
Click the Feeds tab, then Add New Feed.
Select Slack from the list of sources.
Click Add connection to sign in with a Slack account, and approve the permission request when prompted. Once you're signed in, the connection is saved, so you can reuse it to set up additional Slack feeds from different channels without signing in again.
Select a Workspace, then select a Channel.
Optional: add an AI instruction to shape how incoming messages are handled.
Once everything's filled in, click Save new feed.
Each feed connects to a single channel. If you want to pull in messages from more than one channel, set up a separate feed for each one — see Single Source Limit in Connecting Feeds to Your Screens.
Adding to a Screen
For the Collection that has your ScreenCloud for Slack feed, assign it to a paired screen:
Open your Collection and select the Screens tab.
Click Connect a screen, and select the paired screen you want to display it on.
It will play in the Main zone of the screen, provided the screen already has a Layout assigned.
To learn how often the Slack content will appear on screen, see Automated Playback and Content Rotation in Creating Collections for Your Screens. For the general steps that apply to any Feed source, see Setting Up and Connecting a Feed.
Slack Account Requirements to Connect to ScreenCloud
Connecting a Slack channel to ScreenCloud installs the ScreenCloud for Slack feed in your Slack workspace and asks you to authorise it to read messages, files, and basic channel information from the public channel you choose. This is what lets the Feed pick up new posts and any attached media as they're sent.
Who can connect: Any workspace member can authorise the app for a channel they're a member of. If your workspace restricts app installs, a Workspace Owner or Admin will need to approve the request, or install the app on your behalf, before the connection can be completed.
Multiple workspaces: You can connect Slack channels from more than one workspace. Each connection is tied to your own Slack sign-in, so a colleague won't automatically see a connection you've made, and you won't see theirs — see Reusing or Sharing a Connection.
If your organisation restricts outbound network access, your IT team may also need to whitelist certain domains before the ScreenCloud for Slack feed can connect. See the Slack entry in Domains & Servers to Whitelist for ScreenCloud for the specific domains required.
What Content Does the Feed Pull from Your Slack Channel?
The ScreenCloud for Slack feed displays your channel's conversations, including messages with media and links. Some content and formatting from Slack doesn't carry across, as set out below.
Channels and roles
You can only select and display content from a channel you're a member of. Public channels are visible in the channel picker as long as you belong to them.
Message types
New messages posted directly to the channel are supported. Threaded replies, and emoji reactions on a message, are not pulled through as separate posts.
Text formatting
Slack's basic formatting, bold, italic, and strikethrough, carries across, along with emojis, which display using their Unicode equivalent, so custom Slack emojis won't render. Other Slack-specific formatting, such as block quotes, code blocks, bulleted or numbered lists, and @mentions or #channel links, is not retained; the underlying text still comes through, without the styling.
Long messages are shortened to fit the post format used on screen, so keep the key detail near the start of the message if it's longer than a sentence or two.
Media and attachments
Images and videos uploaded directly to the channel, or dragged and dropped into the message, display alongside the message text. A video shared as a link rather than uploaded directly displays as a QR code instead of playing on screen.
Links shared in a message appear on screen as a QR code linking to that page, rather than as clickable text.
If a message includes a file type that can't be displayed directly on screen, such as a PDF or a Word document, the file itself won't render, only the message text and any supported image or video in the same message will show.
If a message has more than one video or link, only the first is used; the rest are ignored.
Managing What Shows on Screen
Once the Feed is connected, you have several ways to control which Slack messages end up on screen, and to review or adjust them afterwards.
Filtering Incoming Posts with AI Instructions
Use AI Instructions to control what comes through from the channel before it reaches your screens. Write your own instruction or choose from the built-in templates to rewrite, filter, or translate messages as they arrive. For a Slack channel, this could mean:
"Only show messages related to company announcements or events."
"Filter out casual chat and bot notifications, keep only official updates."
"Summarise long updates into a single screen-friendly line."
"Translate incoming messages from English to French."
You can test an instruction against your existing Slack posts before saving it, to see exactly which messages it would show or hide.
Managing Posts After They've Arrived
From the Collection's Posts view, you can manage individual posts the Feed has already created:
Hide a post to temporarily remove it from rotation without deleting it.
Show a hidden post again to bring it back into rotation.
Delete a post to remove it permanently.
Since the Feed only reads messages from Slack, none of these actions change or remove the original message in your Slack channel — the connection is read-only.
Finding and Previewing Feed Posts
Every post the Feed creates appears in the Collection's Posts view alongside your manual posts, where you can filter the view by Feed of origin to see only the messages pulled in from Slack. Each post also has its own Preview option, so you can check exactly how it'll look on screen before it plays.
See Connecting Feeds to Your Screens and Creating Posts for Your Screens for the full set of options available on posts created from a Feed.
Changing How Your Feed Appears on Screen
Posts created by the ScreenCloud for Slack feed pick up the Theme applied to the screen they play on, including its light or dark mode. See Creating a Theme for Your Screens for how to customize the look of your posts.
FAQ
Can I add more than one Slack channel to a screen?
Yes. Each Feed connects to a single channel, so create a separate Feed for each channel you want to pull from, then add all of those Feeds to the same Collection to combine them on one screen.
What happens if I lose access to the channel?
If you're removed from the channel or workspace, or the app's permission is revoked, the Feed will stop pulling in new messages. You'll need to reconnect and re-authorise access to resume it.
