External Project Slack Channel Recovery
Repair a failed project handoff without creating a second room for the same work.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create a channel-based conversation
Creates a new public or private slack channel with a unique name; the channel can be org-wide, or team-specific if `team id` is given (required if `org wide` is false or not provided).
Why this helps
A project-management tool can report success while its Slack room is missing, leaving the team unsure whether to retry or search for an existing channel.
- Separate provisioning recovery from new project intake
- Require an exact project ID and expected-channel map
- Stop and report conflicts when current channel existence is unknown
Setup
Build it in a few focused steps.
- 1Connect Agent mail and Slack if supporting mail context is needed.
- 2Send Notis a webhook containing the exact project ID, expected-channel map, prior receipt, and trusted current-channel check.
- 3Describe that it may create only a proven missing channel and must report conflicts.
- 4Choose the Slack run-report channel and test with one failed handoff packet.
Questions about this workflow
What if the external tool does not provide a current channel check?
The workflow stops and flags unknown state; it does not create a duplicate channel.
Is this for opening a brand-new project room?
No. The new-project intake workflow handles approved new projects; this workflow repairs an existing project's missing provisioning.
