Remove an E2B webhook from a Slack cleanup request
Close the loop on a retired integration by turning its cleanup note into a webhook removal.
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
Delete Webhook
Tool to unregister a webhook and stop receiving lifecycle events. Use when you need to remove a webhook that is no longer needed or to clean up webhook registrations.
Why this helps
Old notification routes can linger because webhook cleanup is easy to forget after a project ends.
- Makes webhook cleanup part of the project wrap-up conversation.
- Stops lifecycle notifications from an E2B webhook the team no longer needs.
Setup
Build it in a few focused steps.
- 1Connect Slack and E2B to Notis once through the portal.
- 2Create the automation through the portal or ask Notis to set it up in plain language.
- 3Instruct Notis to unregister the specified E2B webhook when a Slack channel message confirms that it is retired.
- 4Choose the Slack channel message trigger and a channel for run reports.
- 5Test with a real webhook retirement request for a webhook that can be removed.
