Create a Cloudflare WAF list from an approved Slack request
When a request is approved and includes the needed list details, Notis can create the empty WAF list in Cloudflare and report the run.
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
Create WAF List
Tool to create a new empty waf list for the account. use after confirming the account id. example: create list(account id="<id>", kind="ip", name="blocklist")
Why this helps
Approved setup requests can stall while someone copies requirements from Slack into the Cloudflare dashboard.
- Move clear, approved setup requests forward.
- Reduce manual re-entry of list details.
- Make incomplete requests visible for follow-up.
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 create an empty WAF list from approved Slack requests.
- 3In one plain-language instruction, require explicit approval and the account, list kind, and name; tell Notis to flag missing details.
- 4Select the Slack channel message trigger and choose a channel for run reports.
- 5Test with one approved request using a safe, distinct list name.
Questions about this workflow
Will it add entries to the new list?
No. This action creates an empty WAF list.
What if the request is not approved?
The instruction should direct Notis to wait for explicit approval and report incomplete requests rather than create a list.
