Use a Slack reaction to save a Hookdeck event
A consistent reaction can turn a team's lightweight follow-up signal into a bookmark that is easier to revisit.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create Hookdeck Bookmark
Tool to create a new bookmark. Use when you want to bookmark a specific event for quick access.
Why this helps
People may acknowledge an event with a reaction but forget to save its reference somewhere searchable.
- Turn a familiar team signal into a saved event reference.
- Cut down on copying event IDs into separate notes.
- Make follow-up easier to pick up later.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hookdeck to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3In one instruction, tell Notis which reaction signals a bookmark request and to use the referenced Hookdeck event identifier when available.
- 4Choose the Slack message reaction added trigger and a channel for run reports.
- 5Test by reacting to a Slack message that includes a real Hookdeck event identifier, then verify its bookmark.
Questions about this workflow
Can the reaction contain the event identifier?
No. The identifier needs to be present in the Slack message or otherwise available in the event context.
Can I choose any reaction?
Describe the reaction your team will use in the plain-language instruction.
