Apply a Cloudflare DNS update with a Slack reaction
Use a reaction to mark a DNS edit as approved and ready. Notis can update the existing record from a clear request and report the run.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Update DNS record
Tool to update an existing dns record within a specific zone. use after confirming both zone and record identifiers; only provided fields are modified.
Why this helps
Approved edits can be hard to track when a conversation does not clearly show that someone has taken ownership.
- Make approval and readiness visible in the message.
- Reduce manual follow-up after a DNS decision.
- Focus changes on a clear, identified record.
Setup
Build it in a few focused steps.
- 1Connect Slack and Cloudflare to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis to update a DNS record after the agreed reaction marks a change as approved.
- 3Write one instruction requiring the reaction, explicit approval, and enough context to identify the existing record and requested change.
- 4Select the Slack reaction-added trigger, optionally filtered by the agreed emoji or channel, and choose a reporting channel.
- 5Test with one approved update to a record you can verify.
Questions about this workflow
Does the reaction alone specify what to change?
No. The message should clearly state and identify the approved DNS change.
What if the record cannot be identified?
Tell Notis to flag the request for clarification rather than update a guessed record.
