Remove Slack posts that browser checks prove outdated
Stop outdated instructions from circulating by checking the source and removing the specific contradicted post.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Delete a message from a chat
Deletes a message, identified by its channel id and timestamp, from a slack channel, private group, or direct message conversation; the authenticated user or bot must be the original poster.
Why this helps
Incorrect instructions can remain easy to find in Slack even after the authoritative source has changed.
- Remove a specific post when a trusted source proves it outdated.
- Reduce the risk that teammates follow superseded instructions.
- Tie the deletion decision to a defined browser check.
Setup
Build it in a few focused steps.
- 1Connect Anchor browser and Slack once in Notis.
- 2Create an automation in plain language or open Automations, then choose New Automation.
- 3Specify the trusted source, exact contradiction rule, and Slack message to delete only when the correction is verified.
- 4Choose the Notis webhook trigger and select a channel for run reports.
- 5Test the source comparison and message identity with one example before enabling deletion.
Questions about this workflow
Can a deleted message be restored?
The action deletes the Slack message. Treat it as a permanent removal and use a strict verification rule.
What information identifies the message?
Slack requires the channel ID and message timestamp, and the authenticated user or bot must be the original poster.
What if the source is unclear?
Have Notis report the discrepancy for review and leave the message untouched unless the contradiction is explicit.
