Better Context: Custom Preview Cards for Google Slides Links
Slide links in Slack are usually blank previews. Notis unfurls them with custom titles, descriptions, and thumbnails so people can see what they're clicking before they open it—reducing friction and increasing engagement.
Trigger
New Slide Added
Fires when a new slide is added to a Google Slides presentation.
Action
Customize URL unfurl
Customizes url previews (unfurling) in a specific slack message using a url-encoded json in `unfurls` to define custom content or remove existing previews.
Why this helps
Slide links in Slack preview poorly and people don't click because they can't see what's inside.
- Better previews increase click-through rates
- Context is instant—no need to open the link
- Customized branding makes slides look professional
Setup
Build it in a few focused steps.
- 1Connect Google Slides and Slack.
- 2Create an automation named 'Customize slide link previews'.
- 3Enter: 'When a slide link is shared in Slack, customize its preview to show the presentation title, a brief description, and a thumbnail image.'
- 4Choose 'New Slide Added' as the trigger (or set it to fire on all slide shares).
- 5Share a test slide link in Slack—you'll see a rich preview card instead of a blank link.
Questions about this workflow
What information appears in the custom preview?
Mention in your prompt what you want shown—title, description, creation date, creator—and Notis will pull that data.
Can I customize the look or colors?
Notis uses Slack's unfurl format. You can't change colors, but you can control what text and images appear.
Does this apply to all slide links or just new ones?
Specify in your prompt—new slides only or existing slides too—and Notis will apply it accordingly.
