Make event registration links easier to share

A registration URL shared in Slack can become a short Dub link while the event details are still in view.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Upsert a Link

Tool to create or update a short link in Dub. Use when you need to create a new short link or update an existing one. If the link already exists (matching domain and key), it will be updated; otherwise, a new link will be created.

Why this helps

Event details are easy to lose in busy channels, and long registration URLs take extra effort to reuse.

  • Create a concise link from the registration destination.
  • Make event promotion details easier to reuse across messages.
  • Avoid revisiting Slack just to copy a long URL.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Dub to Notis once through the portal.
  • 2Ask Notis to create an automation that makes a Dub short link for event registration URLs posted in the event planning channel.
  • 3Select the Slack channel message trigger and the channel for run reports.
  • 4Test with one real registration URL.

Questions about this workflow

Can I use this for webinars and in-person events?

Yes. Describe the event types and the channel where their registration URLs are shared.

Will it act on venue or calendar URLs too?

Specify in the prompt that only registration or signup destinations should create links.
