Check Docker Hub repository webhooks from Slack
Ask for a repository's webhook setup in Slack and let Notis retrieve the current list for a quick configuration check.
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
List Docker Hub repository webhooks
Tool to list webhooks for a Docker Hub repository. Use when you need to retrieve all existing webhooks after confirming repository details.
Why this helps
Webhook troubleshooting often means searching settings while keeping the original release conversation in mind.
- Keeps webhook checks close to the reported issue.
- Reduces the number of steps in a release investigation.
- Makes current notification configuration easier to review.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docker Hub to Notis once in the portal.
- 2Create an instruction to list webhooks for a Docker Hub repository when a channel request names the repository.
- 3Select Channel Message Received and choose a channel for run reports.
- 4Test with a real request for a repository whose webhook settings you can view.
Questions about this workflow
Does this create or change webhooks?
No. It lists the repository's current webhooks for inspection.
Can it look up a webhook without a repository?
The request should identify the Docker Hub namespace and repository so Notis knows which webhooks to list.
