Retry result delivery with a Slack reaction
Give a known delivery problem a simple follow-up signal so it does not sit forgotten in a busy channel.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Resend Result Set Webhook
Tool to resend the webhook for a previously generated result set. Use when a result set's webhook delivery needs a retry.
Why this helps
Webhook delivery issues often require someone to remember a separate retry step after the original discussion moves on.
- Turn an agreed reaction into a visible retry request.
- Reduce forgotten follow-up after delivery issues.
- Keep retry intent attached to the relevant Slack message.
Setup
Build it in a few focused steps.
- 1Connect Slack and Countdown api to Notis once in the portal.
- 2Create an automation prompt telling Notis to resend a webhook only when the agreed reaction is added to a message identifying a failed Countdown result delivery.
- 3Select the Slack message reaction added trigger, choose a run-report channel, and test with one known result-set delivery case.
Questions about this workflow
Can a reaction alone identify the result set?
The Slack message should contain enough context for Notis to identify the previously generated result set.
Does this generate new results?
No. It retries webhook delivery for an existing result set.
