Customize a Supplied Slack Slide-Link Preview

A supplied Slack message and preview payload are enough to improve how a shared slide link reads.

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

A useful preview cannot be created from a new-slide event without the shared Slack message and approved content.

  • Improves scanability of a known link
  • Keeps preview data supplied and reviewable
  • Does not claim to export a thumbnail from Slides

Setup

Build it in a few focused steps.

  • 1Connect Google Slides and Slack to Notis once.
  • 2Create an automation in the portal named 'Customize a Supplied Slack Slide-Link Preview'.
  • 3Write one plain-language instruction: 'When a new slide is added, customize the unfurl for an existing slack message using supplied preview content. Use only the supplied context: existing Slack message channel and timestamp, URL, approved title, description or thumbnail data, and unfurl authorization.'
  • 4Select New Slide Added and choose a channel for run reports; provide the stated context.
  • 5Test with one real, bounded example and review the returned Slack result.

Questions about this workflow

What is needed to change a preview?

Supply the existing Slack message channel and timestamp, URL, and approved preview fields.

Does this create a Slides thumbnail?

No. Provide usable thumbnail data if needed; the action customizes an existing Slack unfurl.
