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.
