Check existing subscriptions before adding one
A quick duplicate check can make webhook setup more deliberate and easier to maintain.
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
Get Resource Subscriptions
Tool to show all active subscriptions of the user for the input resource. use when you need to review existing webhooks before adding a new one.
Why this helps
Adding another subscription without checking the current state creates avoidable configuration uncertainty.
- See existing subscriptions before setup
- Reduce redundant webhook configuration
- Make setup decisions with current information
Setup
Build it in a few focused steps.
- 1Connect Slack and Gumroad to Notis once through the portal.
- 2Create a new automation called Gumroad duplicate subscription check.
- 3Use one plain-language prompt asking Notis to list existing subscriptions for the resource named in a Slack setup request.
- 4Select Slack Channel Message Received as the trigger and choose the run-report channel.
- 5Test with a resource that already has a known subscription.
Questions about this workflow
Does this add the subscription after checking?
No. It performs the lookup only; a separate subscribe action is needed if one is still required.
When should I use it?
Use it before adding a subscription or when reviewing a setup request.
